Re: [Emc-users] Gluing little balls
if you have done pick and place then just put something like cotton swab (but more durable) and brush hole to spread glue. Maybe Hot glue is alternative too? Then you can use something like reprap extrudor to apply glue.

The problem: The marbles are currently glued in by hand. Painting the glue into the holes, placing the ball and pressing it down gets tedious. I would like to automate this process by replacing the spindle with other equipment. I can automate the pick and placement of the balls. ( spheres may be the easiest item to pick and place) But I have not found a good way to automate the gluing process inexpensively. suggestions? Thoughts? Any help would be appreciated.

They are not that expensive. Proximity of a VFD to sensitive parts doesn't really indicate much. If the hardware is not configured properly (and what is?), the VFD interference can travel through metal frames, conduit, unrelated wires, shielding, etcetera, and come out on the far side of the machine. Sometimes, beads on the output wires can help. Most stepper and servo drives are very similar to VFD's, so they may need power input filters, or output beads too. Most break-out-board inputs (and others) have very high impedance, therefore are very susceptible to induced fields on the input wiring, so even minor interference can show up at the input pin. Think of hitting something hard like a bell. It doesn't absorb or convert the energy very well so it rings until the energy gets converted to sound. Hitting dry sand converts the all of the energy instantly, so it is hard to drive a signal into it,let alone induce noise. I've found that plain buffer inputs have very high impedance and often need some some sort of filter (lowers impedance, adds sand) that matches the type of signal being read. Opto-isolated inputs seem to have more impedance, so are not as much of a problem. Switches and relays with real contacts go from very high impedance to very low, and bounce, so most likely need filtering. Most real machines (my opinion) use 12 Volts for control signals to help push the noise into the OFF voltage region. Others have more experience with this, but I have found that connecting a short piece of wire on my oscilloscope probe picks up interference. I can wave it around my machine and find the noisy spots. It seems some amount noise is inevitable and normal, so expect to need to deal with it, rather than eliminate it. I've heard an AM radio is also good for scanning for interference. I recently set up HALscope to trigger on a suspicious signal. After forcing a trigger on the scope to clear the traces, I sat and watched HALscope until it triggered, then preesed stop to keep the traces form getting written over. This indicated that this signal was on the edge of ON and OFF. A resistor in the line (current limit) and capacitor to ground (low impedance, sand, RC filter) cleared it up. I agree that filtering is good thing to do. But in this case (runnung near 1 hour without problem) the EMI isnt the source of trouble. But high impedance on input pins can be source of trouble here.

(for stepper to but less possible as machine run long time without trouble). Here is some data about the machine: 4 MotionKing stepper drives with Mesa 7i43 for step generation. PC is dual-core Intel Pentium CPU with 1GB memory, no idea about motherboard. EMC version is 2.4.6 running on Lucid. These are the symptoms: 1) EMC won't start running a file, when a PLC (currently controls pneumatics, it will be removed eventually) sends a signal to do so. In HAL file I have: net deb-in debounce.0.0.in= hm2_[HOSTMOT2](BOARD).0.gpio.034.in_not net oneshot-in debounce.0.0.out = oneshot.0.in net oneshot-out oneshot.0.out = and2.0.in0 setp debounce.0.delay 5 setp oneshot.0.rising 1 setp oneshot.0.retriggerable 1 setp oneshot.0.width 5 net ready pyvcp.ready = and2.0.in1 net start and2.0.out = halui.mode.auto halui.program.run Incoming signal from PLC is filtered through debounce and routed into oneshot to watch for rising edge. There is pyvcp button Ready for work for operator to enable EMC following PLC commands. I have been watching these pins in Show HAL Config: hm2_[HOSTMOT2](BOARD).0.gpio.034.in_not and2.0.out halui.program.run halui.program.is-running halui.mode.auto halui.mode.is-auto What I have observed: There are cases, when EMC does not run a file, when PLC sends a signal to do so - I can see that on GPIO pin and and2.0 output pin. The thing is that pins that request changing to auto mode and running a file are true, but EMC does nothing. Resetting the GPIO pin usually solves the situation. So EMC does behave unusually. Blowing out the dust from all the cases - PC, monitor and the box with Mesa card and stepper drives. EMC behaved correctly for ~30 minutes and then this behavior started to repeat once in ~10 minutes. 2) One of the spindles takes a wrong path. The work process is that operator places the material in fixture and presses Start button - pneumatic cylinders hold it in place and spindles conduct a movement, shaping both ends of material. Cylinders release the material, operator takes the part out and puts the next part in and presses Start again. And then repeat this for hundreds of times. I have 2 joints hardcoded to X and other 2 joints hardcoded to Y in kinematics module. The error is that sometimes one of the spindles (not the same spindle all the times) moves less than needed along X thus ruining part. The differene is ~1mm. Most surprising is that after such a wrong move next part is correct. The thing is that deviance of 0.1 mm can already be seen on the part due to the shape of the tool and the shape of the cut. I have a suspicion that this might be something connected with Mesa card and magnetic field from VFD and also spindle motors, because there is CRT monitor ~0,5m from spindle motor and the picture gets creeped. It is good as soon as motor is turned off and gets creepy as soon as it is turned on. The pattern of creepiness changes as the motor moves. If there was a noise in step/dir signals, then the error should remain. But the thing is that in all the cases it recovers and next part is totally fine. The pattern for this error was something like this: No error for first 40-50 minutes. One part ruined. Fine for 5-10 minutes. One part ruined. Fine for ~20 parts. One part ruined. Fine for 6 parts. One part ruined. Fine for 4 parts. One part ruined. Fine for 10-15 parts. One part ruined. Then I lost the track. Confirmed by supervisor - the tendency is that all these errors (and they say that there are other errors that I was not able to observe during 3 hours I was there) get worse and worse as the machine is working.

The thing is that machine works correctly for 40-50 mins, then malfunctions begin to appear - it does not run a file, when button is pressed and some other. Or it ruins a part, just as if motor had lost steps, but the trick is that next part if good without rehoming or any other activity taken - just change material and run the file. And the more machine is running the more often these malfunctions appear. That tells me that some parts in machine are overheating and thus not functioning properly. I would like to blame the dust that gets in all the narrow places on the boards and disturb normal heat dissipation. This seems more driver board problem as PC overheating. If PC overheats then is more possible to hangup. I think you drive some electronic on the edge. Ie if you use printer port that is possible to work just in margin and when heat's up then doesn't work more. But another thing is that you say that after that error you can continue work that is wery strange. And as few people already say. Dry wood dust doesn't harm computer. But they accumulate on all fans and heatsinks and cause problems. Presurized case with fan with filter seems good idea. For monitor's there is no fan so no trouble of that kind should be expected.

They may have limit switches on the slotted bearing so if the machine gets seriously out of square, it trips the E-stop. In this manner, the two linear joints can move relatively together toward home, and then each homes to its own home switch and index pulse. Once homed, then the CNC program always keeps them parallel. I would like to see a picture or video, that sounds interesting. But, let me me rephrase my question… Using gantrykins with a gantry that cannot be out of square more than about 3/4, how can we home the 2-jointed Y axis? We cannot move in World Mode before homing. We cannot move in Joint Mode without racking. We cannot understand how to select one encoder to find index pulse on. Can we home to one of the two index pulses or is this impossible? -Tom If you have stepper then if one stepper lost step you have trouble. To avoid that I think the only option is to have encoder disc on each side and then compare reading pulses from them. As you can tolerate 3/4 (18mm) then encoder can be homemade as it need only one or two slot's (like butterfly for example). And let's do EMC to compare both encoders.

Re: [Emc-users] Simple homing question
Scenario for Homming... 1. Wire both home switch (assume NC) in series and send motor to home and leave motor in just tripped position. 2. Rewire home switches to have both of them readable in port. 3. If both are oppened then machine is in exact position so nothing is needed. 3a. if one switch is untripped then disable motor drive for tripped side. 3b. send other motor to home with own switch. When tripped the machine is aligned. That can be done in HAL without recompiling component's. Nothing in hardware is needed if home switch are routed to controller separatly. All 'relays' to rewire switches can be done with HAL components. And the sadd news. The steps 1 to 3 can be regular HOME command. For 3a/b (aligning gantry) probably the some G code is best.

Re: [Emc-users] EMC2, Compensating for friction
That's not problem of friction at all!. The worst you have is 'sticky' axis. That means you need a lot more power to start to move axis and when already moving the required power is a way smaller. And if that ratio is big then tuning PID is near imposible. You can have low static error or low (or none) overshots but not the both!. So in this point of view the mechanics is bad nad electronic's can't do the job. The ratio can be measured with spring scalle. Just make arm on screw and then pull that arm with scale. Slowly pull until axis move then stop pulling and you have reading just at the point before start and when stoped. (you need some support for pulling as if you pull with bare hand then the 'stop' can't be measured as hand is to 'springy') And if ratio is biger than 1:2 then you have serrious problem. 2011/1/26 Igor Chudov ichu...@gmail.com I have a rotary table (4th axis) that has considerable friction. I know this because the DC servo motor requires at least about 4 amps, to turn the table. The rotary table has a tight worm drive, not some sort of a ballscrew, and the drive is hard to turn. I did try that without the motor, by hand, and it was clearly a bit hard to move. I finally got the table work with EMC2 (thanks to Jon), and have a problem with is a high following error. The error is 0.04 degrees. Since there is a considerable reduction ratio in the work drive, the following error amounts to something like 5 degrees of a turn of the motor (I may be off with my math VERY easily, but clearly it is huge with that much reduction). Right or wrong, I attribute this to the friction in the worm drive system -- the servo motor develops following error when working against friction. I have AMC DC drives working in torque mode. My question is what servo tuning parameters could I use to compensate for high friction. It seems that I almost need FF(-1) or something like that?

C2 is the reservoir into which this pump is pumping positive charge [1]. If C1 isn't driven up and down, charge isn't going to flow out of ground to C2, and its charge decays through R2. The only change I'd make to the circuit is to connect R1 to +5v, so that the default state of IC1A output is low.

There are some tondecoder PLL's like NE567. Cheap 8 pin DIL chip and two resistor's and one cap can solve that problem perfectly. You just need to do software chargepump at servo rate (1ms for example) and got 500Hz output for PLL. That's seems ideal too for me. Can't triger on wrong pulses and react fast.

I think because the MCU is used to validate EMC2 before powering up the dangerous bits of the machine. The MCU's internal watchdog validates the MCU itself(?), which is a separate function. I need to read the MCU manual to see what features come with the using the watchdog. I suppose EMC2 could be used to validate the MCU, but things are getting complicated. Hmmm, its seems Slavko read right past microcontroller's on-board watchdog in my post. :-) Yes, the ATtiny's watchdog is on-chip, so the quandary doesn't arise. I wouldn't trust a microcontroller in any critical role, without a hardware supervisor. On an AVR, it has it's own clock, so even if the CPU clock dies, the watchdog reset will tri-state port pins. That is why a pull-[up|down] to a safe state is helpful on a port pin. It takes over in reset scenarios. The watchdog improves the reliability of the microcontroller by providing recovery from soft errors, whether caused by extreme transients or alpha particles. However, the ATtiny's watchdog is best enabled only after its program has been debugged. ;-) Erik I use that MCU's And can tell you that Watchdog on tiny controlers are good one. But have problems. The mcu itself MUST be started correctly (reseted) and after that watchdog work correctly. But when big machine starts (with a lot of solenoids) the proper reset is wery hard to realize! And belive me that if you think in a way that unproper reset may casuse injury then just stay off that.

Re: [Emc-users] Watchdog Sizing
Just my 2 cents... For watchdog thing I think the ATtiny is just overkill. That kind of operation can be done with simple 555 timer or even few diodes and transistor. Don't get me wrong. The ATtiny (15L) for example can do that job but as safety device the any micro isn't good way. And if system hang who says that it can't set wrong configuration and disable watchdog? Just do that without micro and use micro for other complicated thing.. 2010/12/4 Kirk Wallace kwall...@wallacecompany.com On Sat, 2010-12-04 at 09:55 +0800, Jim Coleman wrote: I like the idea of a dip switch or solder bridges if one doesn't plan on changing the setting alot and wants to save the cost of the dip switch. while the pot would be easy to adjust, it's less precise than a truth table of the dip/bridge positions and the resultant reset timer. Jim Thanks Jim. I agree that it would be nice to have a precise, stable input, but I am also trying to avoid any hardware complexity in order to avoid an upgrade loop (ATtiny - ATmega - Atom Cube - Nanotube Superconducting Buckyball hyper... ). It may also be that one or a few presets might be enough. If charge pump is running at 1kHz (based on servo thread), it may be acceptable to wait up to a hundred cycles or .1 seconds to trip an e-stop. If this is the case, .1 seconds might cover the range of common watchdog frequencies.

It does not add too much time to the make, and you will get the benefit of the document corrections and updates that we are trying to bring you. Someone said that now --enable-run-in-place is the default, and is no longer needed, is this true? If so, perhaps the --enable-build-documentation should also be made the default, and instead have --disable-build-documentation or something similar. Comments? And if anyone has any document corrections needed, or any suggestions for document improvement, please post them to the emc-users list. Thanks for reading.

Re: [Emc-users] ngc file runtime estimation ?
Hmm this seems just right. But I think the feedrate should be taken into acount and then used some normalized value. So if we Have G1 move 10mm long with F10 that should be equal to G1 move 100mm long with F100. And if we precalculate total length(normalized) we can in runtime predict time to end (or percentage). With this the estimated time can be precise even if speed override is used. This should work until some probe cycle is involved. Canned cycles isn't problematic and subs too.. (just need to execute it) But Probe cycle and some other ones can be problematic. Slavko. Viesturs Lācis pravi: Well, just as it was said in the previous discussion, even without functions, subroutines etc this approach sucks, because You can have one line of G1 move for 0.5 mm and second line with G1 move of 3000 mm. They will be treated equally in this approach, while there is difference of thousand of times, how long it actually takes to execute both of them. I think that distance traveled vs total distance to go is more precise approach. Actually that is what I would like to use, but that is not that high priority for me to start investigating that. /vie 2010/8/27 Ries van Twisk e...@rvt.dds.nl: -- Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.

Re: [Emc-users] Unexpected latency problem
Gene Heskett pravi: because the output process to tell you adds to the problem. So it is occurring later even if not reported. Set your BASE_PERIOD for say 50us, and the servo loop time for at least 10x that. Try this, and reduce the BASE_PERIOD 5u-secs at a time until you can just barely note that the machine feels busy and keyboard response loses its instant feel. Add the last 5u-secs back and leave it there. This has worked well for me, on an old Athlon running at 1.6Ghz. My machine work happy with 20us and mouse doesn't stick. So I have 25us as safe. The motor's sound's good but in 30uS the some noise start appearing and goes worse till 45us when motors stall. Longer BASE_PERIODs will have a noticeable effect on how the motors sound at higher speeds because it limits the size of the speed step available and you hear the motors stepping up and down like 2 or 3 key gaps on the piano keyboard. The shorter BASE_PERIODs will make this smoother, and because the motors can follow these smaller steps easier, you can get higher speeds. I have also, at least on my little machine, found that setting the accelerations to smaller values so you hear the motors winding up and unwinding, also helps to achieve the higher speeds. This, like everything else has trade offs because the smaller motions never get to a very high speed. Your broken bit because Z didn't retract was probably caused by the combination of a too high acceleration setting, combined with MAX_VEL also being too high, and when one of those latencies hit, the motor went out of sync stopped, and the next pulses after the latency hit were too fast for the motor of follow from a dead stop. I don't know why. The machine worked without problems. Just got that single 'hickup' once in aprox half of year. That's the reason why I ask for latency error message. Is that apear if latency is longer than base thread or what. I assume that acceleration is ok as work now without problem. I think the error can be some EMI interference or just one bad jitter on computer. So the question is is EMC capable to say that jitter is longer than base period? So the first thing is to find out where the latency is. Personally, the least interfering video driver (which causes 75% of these problems, and poor APIC hardware is often found) turned out to be the vesa driver. The nvidia driver was by far the worst, the nv driver was better, and the vesa driver was hand downs the best. YMMV of course. I haven't ever had an ATI card in that machine, just a series of nvidia cards, which have a limited lifetime, those with fans only last as long at the $0.65 fan they use on them. APIC related problems are best treated with a different motherboard. Somewhere in all the above rambling might be something helpful. I hope so at any rate. The latency error is only reported once, the first time it happens, mainly How to change driver?!? I had what is on live CD and works.

[Emc-users] Unexpected latency problem
Hello... Just one question. What even't triger RTAI error message Unexpected latency error message (showed only once) I know that is report of lattency problem but when is trigered? I have base thread on 25uS so is this triggered when jitter is more than 25uS or what? I have laptop for running EMC. If I startup computer and immediatly start EMC I got that error and if I start lattency test right on startup then I got lattency in range of miliseconds. But after few minutes they dissapear and then latency stay in 15uS range (glxgear running over the 30hour test) I suspect that this is caused as the laptop has no battery (was death) and when charger abort charge the latency problem is solved. Just now I had problem (once) that Z axis was'nt goes up and I broke drill bit. So I don't know what cause that. I suspect if that is jitter problem (over 25uS) i should got message about that but here are no message. I know I have underpowered Z stepper but also have slow acceleration and speed. I't never bind till now. I use phase drive so step/dir timing's isn't cause. Slavko. -- ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.

[Emc-users] Latency and laptop.
Hello... I know that laptop's are not great for EMC, but I have few of them lying around and wish to use it. HP NX9005 work's now for longer time without some troubles. It has some strange thing. The layency in 1'st few minutes (up to 5) is high(in range 1ms). I don't know why but after that they are low (around 15uS) and stay there all the day. more hour's machining isn't problematic. (I didn't disabled SMI) I expect that is caused by death baterry(removed). Now I try to wake up the IBM ThinkPad T23 Pentium III 1GHz 640MB/RAM The 1'st issue was SMI. The 200uS latency every 60 seconds. I disabled SMI and got latency in range 15uS. I leave just latency test running one hour to be safe. (I was surprised as CPU fan is turned on and off few times during that test with SMI off). After that I run glxgears and leave another hour. all just fine. But then I maximized glxgear window and horror of 2 miliseconds appear. I try to open openoffice and was just ok. I can write / open / save no bad latency. But the resizing window (no mather what window) does bad latency. I discovered if I just run latency test and maximize it's window the bad think happens? What can be cause? Video? (S3 Graphich SuperSavage/IXC1014 reported within WindowsXP) Any cure? Slavko. -- ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.

Re: [Emc-users] Jog under PAUSE / tool cnange
John Kasunich pravi: I already wrote half a book last night, and I'm not going to do it again today. Suffice it to say that Run from Line is another one of those things that is incredibly hard to do in a correctly in all cases. If a program uses nothing but G0, G1, G2, G3, then it is relatively easy. But when you start using fixture offsets, automatic tool length measurement, variables, loops, etc, it gets very tricky. I'll bet anyone a pint of their favorite beer that for any suggested implementation of run-from-line, I can come up with g-code that breaks it. If we ever get to the point when I have to buy someone a beer, then we finally have a design spec that is worthy of the name, and that can be used to actually code up the feature. Regards, John Kasunich Just that. And saddly very true. The run from line is not possible to implement. As John says if Only G0,1,2,3 was in program then we realy don't need to scan all data before. Just pick last XYZ... and reuse it. Or if you stop machine and save with G30.1 and do whatever you want and after that execute G30 the machine restore end point and just run from (that interupted line) again wil do just right. (if you use I and J instead R in G2,3 ). If your program has something more (subs, canned) the solution can reach inpossible to implement point. Just imagine that program use touch probe to measure something and store to variable. And after pause the program scans again file until start from here line come. How to store correct value in variable if machine should not move ! So stop thinking in that way. This is just time eater. Instead writting long post the beter way is to make some constructive decision. (or even solution) As I know the three real event are in interest and many not real inportant wishes. And I think we should focus on this three event's 1. Swarf removal Need to pause machine and jog tool out of part, clean swarf, resume position and resume operation. (this should be not to hard to implement Just JOG is needed) 2. Tool change Manual tool change need to jog and to make TouchOff. As interpreter stops already at M6 I think this is not so hard to do too as queue is stoped by M6) 3. Tool change when broken Need to pause machine, Jog and TouchOff. This seem's to be hardest to implement's as machine is probably stoped within line. Touch Off is queue problem. (or not?) So two of option should be easy to implement. the other 33% is harder. So let's make this two operational. This wil make 66% people happier and 33% still waiting. I'm not studied queue operaton but I wonder how is managed. Is there are all coordinates in machine coordinate? If yes then TouchOff need to clean queue. If not then program can resume in that queue when resume is pressed. And this is pointing me to idea to have two queues. One main and one for operations under break. Eg when hitting PAUSE all machine offsets/modals/positions are saved. The queue is replaced the all motion needed is done then when resume is hitted machine restore previous queue restore all saved data restore position and continue queue operation.

Re: [Emc-users] Jog under PAUSE / tool cnange
I like that description John. I'm myself are aware of problems of realtime programming as I do that daily with microcontrollers but other user's doesn't know that problems. I know that editing/modifiing realtime software is pain. You make new function and other one stops work as should. It's nasty. And my program's are up to about 40 kilobyte of machine code and EMC2 is hughe. But! Yes there is But. It can be done! And it should be done! Why? Beacouse all workaround are so messy and dangerous that we should minimise risk! Is someone milling plastic and swarf catch the tool the user want to pause and cleanup the tool as they know that this mees will burn part. And how he can do that? It can pause machine and can stop spindle(not in emc but there should be some external controll too) Now the plastic can be wraped around tool and the only way to get it out is to cut that from spindle as we can't jog in out of the work. And cutting with sharp knife in sharp tool isn't good idea. another one: The user drill printed circuit board. They broke drill bit and pause machine. How to replace it? In software as is there are no way to do that. But has some messy workaround. as stop program jog machine and resume last line and forgot that pisece of broken bit is in that hole and restart just to broke another one. But if we PAUSE machine the motion queue can be cleaned! For resumming we only need the last (paused) position and line where it happens to resume on just right spot and fill up the motion queue with new data. It can be done. And the last. The people (developers) makes great program for free. So we can only to have wish what we want and they wil decide if thing wil be done. That's true. If they don't need that stuff then this will be done latter.(if at all) Is someone of developer come to Slovenia then just drop the mail and I wil fillup the fridge with beer.

Wright watchma...@talktalk.net wrote: As my initial suggestions - I can't see why the program would have to return to exactly the same place in the script as it was when it was paused before the jog surely it could return to the start of the 'block' or line it was cutting at the pause.. This would be simpler (I think). You basically throw away the queue when pause is pressed and run from line but if you imagine needing to unclog a cutter near the end of a very long slot, you could have been in that same G-code line for 20 minutes. Assume program: N1 G01 X100 Y100 N2 G01 X300 Y-10 N3 G01 X0 Y0 If you stop/pause that progran let's say in N2 just before they end and save coordinate like G30.1 and do jog or whatever... And if you restore coordinate like G30 the machine wil go to the point where is paused (linear line) and if you rerun line N2 it wil do just smal move to the end at X300 Y-10 not the whole thing from X100 Y100 to X300 Y-10 It should work at least with G0/1/2/3 (G2/3 with radius can be problematic but not with I,J) In case of canned cycle the restore of Z axis can be problematic. I think to restore from backoff Z is much safer. (and to decide retry last canned cycle or skip to next) For my knowledge the only stop point and line is needed and queue can be cleaned. The stop point can be probably saved (we must wait to machine do real stop with deceleration) and line is already known.

Re: [Emc-users] Jog under PAUSE / tool cnange
Hello... Not bad idea to be separate item as jog under toolchange can be resolved quicker. I changed wiki and I think all command M0 M1 and M6 can behave similar. For example if someone mill plastic then can issue few M1 in program and has optional stop on M1 dissabled. If swarf come up then just enable M1 pause and have nice workaround. Maybe there is not bad idea to have another one pause button that pause program like inserting M1 after just current line?!? Easyer to implement. Beaware of one nasty thing with manualtoolchange.py! When window popup the keyboard control is on that window! If someone uses Estop in keyboard and something goes wrong during toolchange dialog then Estop button wont work! Slavko Ries van Twisk pravi: Salvko, i think it would be a good idea to seperate item 15 into two items: 15) JOG under PAUSE - Alow users to jog machine when program is paused. 16) JOG under ToolChange - Alow users to jog machine when program M6 executed. The TouchOff? should be enabled too and maybe even MDI Although they look the same, the problem domain is in both cases somewhere else. As noticed before, item 16) is possible easer to solve then item 15) because of various internals With 15 it would be just fine if you can jog out, stop the spindle clean the workpiece, clean the bit and the machine and continue. For me personally it would already be awesome if when I press pause the tool will just move up and spindle stop (not need for jogging) The problem with 15) is that you can pause in the middle if a running line, and it's hard to re-start in the middle of an operation. With 16) The machine stops at a distinct line and already can continue from there, we just need to have a way to touch off (can that be done with the modified manual hal toolchange??) If they are broken into two piece, it will be easer to solve because a programmer can just concentrate on a easer task.

Re: [Emc-users] Jog under PAUSE / tool cnange
Offsets are applied in the interpreter, and the already-offset motions are queued for the motion controller to execute. If you change the tool offset, the queue has to be discarded and re-filled with a new set of offset motions. Executing G-code can change the interpreter state, e.g. by changing variable values (or coordinate offsets, G90/91 motion modes ...). This increases the complexity of re-running code quite a lot, since we would need a way of returning the interpreter to the state it was in when the executing motion was queued. That's not an easy problem. - Steve There is one (nasty) thing when run from line is applied. The queue is cleaned and program resume from selected line but not with correct modal parameters!

It's not just hal_manualtoolchage either, the OS can pop up a window or change focus for any reason, at any time.

If user pause machine and stop spindle collant's or whatever or jog machine the 1'st thing when machine resume operation is to move xyz to last coordinate in linear move.

Re: [Emc-users] OT quick question on sizing flyback diodes.
Greg Bentzinger pravi: I'm putting a small H-bridge together using TIP121/126 to replace a SN754410NE. The schematic I'm following didn't list any values for the flyback diodes. In fact some examples left them out. I know that when this circuit is in use it switches from full forward to full reverse with no ramping. This tends to overheat the SN754410NE with small motors and blow it with motors slightly larger. The H-Bridge is driven by a LM339 and about the only adjustment I have is the amount of deadband between directions. My question is how to determine values for the flyback diodes. In the past I used the motor stall current spec to be on the safe side. In other circuits I often see very small diodes like 1A on a 7A drive. Also voltage rating, does the back EMF rise much greater than the supply voltage? If so how much higher % should one use? Since someone will ask - this is the ram servo control for a small tabletop sinker EDM - the abrupt movements really aid in flushing as well as breaking momentary shorts sometimes caused by debris in the work contact area.

However, each time I start up EMC2 and hit Home for the Z-axis, it ends up at a different reading. i.e. EMC2 doesn't seem to be consistent in how it starts and the Homing procedure doesn't reset the home position. For example - I have set the ini file to home to 0.00 and then to back off to -2.00 (it is +2.0 in the ini file..). I just closed down EMC2 and restarted it and hit Home for the Z-axis. The machine did its thing and settled where it should physically - just off the switch - but the AXIS readout said -4.000. I repeated the shutting down and restarting and this time it settled in the same physical position reading -3.500. Another time it read 5.220 - in each case, all I have done is start EMC2, jog the Z-axis away from ) a bit and hit the Home button in AXIS so I haven't affected any of the other functions at all. Is there no way that the display can be automatically made to reset itself to the ini file setting ( in this case -2.000) when an axis is homed or do I have to manually 'touch off' each time.

Re: [Emc-users] Musings on Spindle Encoders.
2010/4/24 Andy Pugh a...@andypugh.fsnet.co.uk The usual sort of encoder is not desperately convenient for mounting on a machine tool spindle, as such applications generally require a sizeable through-hole. Car engines nowadays use a pickup on the crank to tell the engine controller the current crank angle. These used to be a proximity sensor on the starter ring-gear. To get an index pulse one or two gear teeth were machined short, a scheme normally referred to as 32-minus-1 or 64-minus-1 or whatever the engine actually had. Thus the index and the pulses were detected by the same sensor. Nowadays this is rarely the case, the typical crank sensor ring is a magnetically encoded disc mounted behind the crank pulley. Typically with a pressed-steel hub with a 3 or bigger through-hole. In fact I have pressed one onto the outside of a 4 2-Jaw-chuck on a test rig. The advent of stop-start-stop systems on vehicles (which I hated the idea of but actually quite like in practice) has meant that engines are now required to start from hot in 0.3s or less. The single-sensor systems can't tell when the crank has rotated backwards as the engine stopped, so it has to wait to see an index before it can inject fuel and start. This can take a significant proportion of the allowed time. So, the latest development is a dual-pickup using quadrature to detect back-rotation. This suddenly makes them look quite attractive for CNC machine use. These devices are inexpensive commodity items intended for rough service. I think the sensor is $5 and the ring $20. The only reason that we can't use them on tool spindles is that the missing tooth index scheme is not suported by EMC2. I wonder if it is worth adding it? Missing tooth scheme can be very good idea to EMC. In that case the sensor are cheap, the gear can be made with drill press (thing can do the work with only 3 tooth and 1 missing) and at least the only one pin on printer port is needed. The best way I think is to make just one more RT component that have one input pin from outside world (missing pulse input) and two output pins (phaseA and Index) so in HAL that can be coupled on just any other component.

[Emc-users] Unhome on ESTOP
Hello... I looking for solution how to unhome machine if Estop button is pressed. If I pressed ESTOP the power to the motor's are killed. So when I relase estop and engage power the position on display is wrong. I find best solution is to flag axis as unhomed to force rehoming. Just can't find right pin where to connect estop button to clear homed flag. Any help? Slavko. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

[Emc-users] User to demanding. (Or just lost?)
Hello... Now I'm totaly lost. What version to use? Is there safe version? The story.. I hit (expensive) bug in 2.5.0~pre check [Emc-users] Tool Crash when STOP So I go back to 2.3.5 and recompile with latest stepgen.c Now another thing doesn't work see [Emc-users] Unhome on ESTOP Someone pointed me to 2.4~pre (where to get that?!?) and what will doesn't work here? I search the wiki to see what version is 'latest'. It's seems to be 2.3.5. But all documentation is for never version 2.4 I know that this is open project but is there someone to clearly say what version is best?!? As I read maillist I fell like to demanding person to use emc?!? ... but I just like to have safe working system. .. and want to help to be better. I had few versinos of EMC on computer. but none is functional.

Re: [Emc-users] User to demanding. (Or just lost?)
Andy Pugh pravi: (Note that I am not a developer, nor do I speak for the developers) As I understand it, 2.4 is now frozen, there will be no new features added, just bugfixes prior to release. Probably you have right here. Look on the bright side, if you used one of the closed-source controllers you wouldn't have most of these features, and you would have no way to do anything about it either. You have right here too. From what Michał Geszkiewicz has said it looks like your best bet is to grab the latest 2.5~pre master from Git and use that. I am not clear if e-stop latch is working as you want but you already had a solution to that in HAL which worked. I just downloading from scratch that. If move after stop problem is solved then no problem. Estop latch can be fixed to. It's not my needed feature. I just want to work as in documentation is stated. I am not sure that the existing function is technically wrong either.The watchdog is there to kill the machine if the computer crashes. You could take the view that if the computer is running then it is the job of the controller to look after motion and any time EMC2 is live the watchdog should be too. It's not same as documentation say's So we ned to change one to be consistient. About watchdog. I have ESTOP button hardwired to cut out power line for complete machine. (drivers/spindles) But in series of that I have one relay too. So if I want to engage machine without EMC can't do that. I must start emc to have operational power for drivers. The term watchdog from estop_latch can make mess. As I use just for chargepump not watchdog. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

Can you describe what you have changed in estop-latch and what the side
effects are?
I use estop-latch with all my products. The watchdog in that case is in
the external hardware, so I don't need to have a software one.
Jon
In the documentation for estop latch from
http://linuxcnc.org/docs/2.4/html/man/man9/estop_latch.9.html
is stated:
While ok-out is true, watchdog toggles, and can be used for chargepumps or
similar needs.
And I want just that!
But in reality the watchdog togles if ok_in is true and fault_in is false.
They not observe if latch is reseted.
So I change source estop_latch.comp to match the documentation. Ie the
watchdog output togle only if ok_out is true.
the change is on only one line!
Instead
watchdog = !watchdog;
i write
if ( ok_out ) {watchdog = !watchdog;}
And thing work's as is stated in documentation.
and gere is git output. And I don't know where how to post it.
I don't want to make some direect upload (probably I can't too) but some of
developers check if I make something wrong before updating.

Dave pravi: is great, everybody should be thankfull for others work, and obviously work together and not against each other. I agree.. Bernhard, I really appreciate your efforts at the filtering.. and the interaction with the other developers, Epler, Alex, Cradek, SWPadnos.and others ..etc. I am constantly impressed by the speed at which communication and collaboration take place regarding EMC2. I need to do some filtering work and I didn't notice that a change had slipped out of the master.. I'm sure we can get it slipped back in if that happened. ;-)I need to go back and look at that patch again. I can appreciate Slavko's frustration if he has an outstanding issue, but compared to dealing with a commercial control company or other closed source CNC software, the help available from the EMC2 community is fantastic!! I simply can't express my gratitude sufficiently to the many people on the IRC and this list who have helped me out. THANKS! just doesn't seem to be sufficient. Dave (Dave911 on the IRC) Hello... I don't want to blame EMC2 community. If I do that then it's not intentionaly. As my english is no so good there is big chance to some post from me can be missreaded. I'm still new in emc2. I'm new to linux too. To be worse I can call myself as newbye for CNC too. I have small CNC for drilling PCB circuit board over 20 years. It's made entirely from aluminum but is to light to make some other thing. so few years ago I start 1m x 0.5m wood router and 30cm x 30cm router.(Before that I made some MDF routers just for fun and learn lot) As smaller is done I make some parts and hit some problems too. I'm not machinist. For now I made just few jigs and few PCB on machine running EMC. the 1'st problem I have is my unconventional motor driver. I need to add custom phase drive. As I only change the last phase sequences (to be able to run machine) the patch 'arrive' just two day's latter. I very like that. The other's two problem's (webcam tab and homming report) sems to be not accepted in comunity. I like webcam as I find it easyest way to center drill holles for PCB. I have that on old machine I see that on MACH3 forum and is pretty hard to understand why not in EMC. I was trying to incorporate it but fail as my knowledge to python in nill. Now I bother with different window's flying around desktop. I do have more wishes for EMC functionality but a lot of them public doesn't need it. But thing's as webcam or home repport I think the public want just doesn't aware the benifit's of it. and again. I don't want to blame people making EMC! If i'm unhappy when my idea is rejected then that's my problem. I'm programmer too (just other languages) and know how many free hour's take project like EMC2.

But thing's as webcam or home repport I think the public want just doesn't aware the benifit's of it. I can see the value of the homing report. Perhaps if a machine that is already homed is re-homed and the new home position and old position differ by more than a certain amount then a following error should be triggered? (Or perhaps just an information note) It seems to me that if the home position has moved then there is an error, and the user should be told. Most of the time they probably know, and are re-homing because of it, but for those of us running open-loop with steppers it would be valuable information. ... What to say... Agree. While I'm not C programmer I throw view in source to check how to manage that. But I'm lost. The home routines are in separate file but are little complicated. I have simple aproach in mind. When home move is ended just calculate difference from current position and home position. But found that isn't so easy. The machine coordinate are preseted in midle of sequence too. As machine need to reset coordinate in correct place to get screw compensation ready. Other option seems to be something like: save all joint's positions call doHome calculate differences and print message ...but can't find that doHome point. Seems that homing is just initiated and finish is in motion routine. ?!? just to much for me...

Re: [Emc-users] Homming error
Dave pravi: I agree that the homing report could be a valuable thing.I think you are assuming there is no support for a homing report, but I didn't notice anyone asking if anyone thought it was a good idea or not. Sometimes noise will get on Servo encoder cables also and cause positioning errors also, so it could be valuable to a servo system. I'm not sure that what is wanted couldn't be done in Hal right now.. on the edge of home, switch grab the current axis position count, display that on a PyVcp screen ?? If the result isn't zero or whatever it should be (it should always be the same or close) then you have a problem. I was try some thing but for now I got false reading all the time. Regarding the video inside of EMC2; Slavko, are you using another app in a different window right now? Why doesn't that work for you?When Yes. I was able to make thing ussable. It's ussable but not practic. Let's see what and why. If I arrange all windows to not overlap then all are too small so in first place I maximize AXIS interface. (why can't be started maximized at all?!? Or at least remember last position?!?) After that I start Camera window. I right click camera window and select always on top and move that window over AXIS preview place. (just fit inside) After that I start Learn.py and make that window always on top too and move over code window of AXIS. So now I have all windows visible doesn't matter witch is selected. Now I must click somewhere on AXIS interface and jog machine to reference point (with help of webcam) After that I must select and click Learn/Position. Then again I must click somewhere on AXIS interface to select it and repeat jog move to other reference points. And repeat that for all reference points. It's very easy to mess the selected window and keystrokes. I think to easy to make mess. After that I close the cam window and learn window. The coordinate of reference points are stored in file. All that just to save current coordinate in file. (under jogging) The old Turbocnc Can do that with single keypress. And modern CNC machines too! Few times I must scan hole position for PCB board. And in more machine procedure is same. Jog over the hole (with help of camera or optical finder) and pres single key to save coordinate. I don't understand why on EMC2 is too hard to have same thing?! (well keyboard shortcuts are pretty bussy). they put the video window inside of Mach3, that caused all kinds of issues and it seems like no one is happy with the size of the window within Mach3, the way the cross hairs display etc, etc... Then you can get into camera differences also. So many desires, and so little time. ;-) Dave (Dave911 on IRC) After digging into camera stuff I realized that linux just doesn't have (yet) good camera support. They need a bunch of drivers and tweaking. So the code to grab picture inside AXIS seem's not good way. Simply won't run on all computers. But I think if the another tab for webcam just reflect image from some pipe od even webcast (streaming video) then thing is a lot easyer. I find few videostreaming packages and work's with different cameras. I try to run some on these and result is ok. I can have live video in firefox browser on EMC2 machine and on other (XP) machine in same time.So it's works. It can be done. Someone want that?

Re: [Emc-users] pin configuration for diy xyz stepper controller
Andy Pugh pravi: ie, assuming that Pin 11 is the all limits and all homes pin then set it to be the combined pin for the X axis and then edit the hal file to combine all the axes on one pin. Something like: net all-homes-and-limits parport.0.pin-11-in-not = axis.0.home-sw-in axis.0.neg-lim-sw-in axis.0.pos-lim-sw-in axis.1.home-sw-in axis.1.neg-lim-sw-in axis.1.pos-lim-sw-in axis.2.home-sw-in axis.2.neg-lim-sw-in axis.2.pos-lim-sw-in (All on one line, ignore any spurious line wrapping). You will need so assign a home sequence number to each axis so they can home one at a time or EMC won't know which one has hit a limit. Note also that this might not actually work, I have not tried it. You might need to use some slightly more clever logic (AND functions or similar) to prevent inactive axes faulting when another homes. However I think that limits should be disabled during homing by default Nope. Isnt' dissabled.

Re: [Emc-users] couple of questions
Chris Reynolds pravi: I've been using EMC2 now for a while and I really like it. I just have a couple of questions. A lot of the parts I'm making require tool changes, and what I've found is that it would be really nice to have the program run a section, then pause so I can jog the machine, change tools, touch off, then resume the program. I've been using M00 to pause the program at different points so I can change tools, however I have to actually stop the program in order to jog the machine and do my tool change, then after I'm done I have to touch off again, then highlight the next line of code in the preview window at the bottom and then right click and select start from here. Is there a better way to do it? I'm honestly not well versed in gcode since I'm self-taught, but I'd like to streamline my process if it's possible. It's nothing critical mind you, and it's in no way a complaint against EMC2, just something that I had been wondering about. In fact it was only the other night that I learned that while touching off I could use the I and C keys to jump back and forth between constant jogging and interval jogging and then use the END key to set the offset. hahaha I know I know I'm probably WAY behind on learning gcode, but anyway if anyone has a suggestion I would be most grateful. Chris For jogging just look little back to the topic Jog under pause/toolchange if you lazy one then just check http://article.gmane.org/gmane.linux.distributions.emc.user/17898/match= and use it. When program hit's M6 you can jog machine. And Warning! Jog machine back to the position where was before M6 so be shure the path is free.

Re: [Emc-users] Homming error
Jon Elson pravi: The problem with the homing report is the destruction of data. When the home position is found, the machine position count is set to zero (or whatever the HOME_OFFSET value is). So, the old home position is destroyed by that operation. Just that. Before writing that HOME_OFFSET just read previous value and show difference. But doesn't work! The destruction of data is done earlyer too! That's is done to screw_comp file come at right position! So isn't simple as I think.

When the home position is found, the machine position count is set to zero (or whatever the HOME_OFFSET value is). So, the old home position is destroyed by that operation. To stay with the canonical encoder definition as it is, you would have to store the position JUST before the home operation completed. I think you could make a custom HAL component that recorded the machine position every servo cycle. Whenever it saw ENCODER_INDEX transition from true to false, it would save the value recorded from the previous cycle. This would be the position one millisecond (at the default SERVO_THREAD rate) before the home position was found. I think this would give you a pretty consistent way of checking for drift of the home position. On the first home whe EMC is started, it would show the distance traveled from where the machine was to the home position. On later homing operations, the value should be very close to zero, assuming the approach to the home switch is slow. (Maybe watching ENCODER_INDEX only works where the index pulse is being used, how does the position count get set for stepgen, for instance? I'm only familiar with servo-like interfaces.) I think this will work if there's a signal that tells you the home operation is happening NOW, and doesn't require any change to EMC2 itself. You would monitor this with HalMeter or the show hal signals menu. Jon Hi Jon, Slavko is running steppers so I believe he has a base thread running also which should be plenty fast enough to catch the step count just before hitting the home switch. :-) And if not, then I would think that a base thread could be added to increase the accuracy. Just has to be worked out. Dave Dave you are right. It's stepper based. And base thread is set very conservative at 50uSec. Stepper's start buzzing if I set base period at 60uS and computer's fell lazy is I set BT at 20uSec. Latency of system is aprox 16uSec. I have no problem with dir/step timming as I use phase drive.

Re: [Emc-users] Homming error
Roland Jollivet pravi: You could implement a similar function using a contrived method, that is not part of the G28 command or other homing function. Basically you would have a subroutine to deliberately move the machine to the home switches and write the x,y,z values to file as the switches are crossed. Assuming they should be 0,0,0, the new, 'wrong' values might be 0,3,0. Then a program outside EMC could interrogate the file data. It might also be time stamped. The routine would then have to move back to resume machining. So depending on how critical your project is, you could use a text or other editor to insert this gcode as a call function every 500 lines, or 1000 lines, or maybe after every tool change, into your gcode before you run the file. I don't know how difficult it would be to implement this using EMC. When I worked with an Emco mill(stepper), some programs ran for more than 24hrs. I wanted to insert a 'home' call at the start of every new pass. If a few steps were somehow lost, at least one would be starting with a 'clean slate', and not have an incremental error. But it could not be done. Roland PS (now I'll wait to get shot to pieces by the gurus...) I'm not shure what you mean. The problem to handle this is that switch is limit switch too. So any code moving axis can't reach that switch as soft limit is trigered before. If I override soft limit then switch act as limit and triger hard limit..

Re: [Emc-users] Homming error
Dave pravi: In my experience with steppers that are running on the edge (mechanically or electrically), they almost never lose steps the same amount in both directions. Best thing I can think of doing is to put a 1 dial indicator on the questionable axis, write a test program or better yet, patch an existing one, so the axis deflects the indicator and pauses there, then goes away from the indicator and runs a lengthy program away from the indicator then have it come back and touch the indicator at the end of the run. If you do that right, you can loop the program and let it run for a while, if anything is out of wack, that will show up as a changing indicator position. You can work the home thing out also, but the dial indicator thing is is a lot more flexible IMO and works on almost all machines.. If your machine is way out of wack, be careful how you mount your indicator so it doesn't get wiped out if the machine is erractic. Dave For now my machine work o.k. But in very rare case I got small error and wan't to know when. I'm talking for drilling PCB for example. When you drill PCB and got somewhere error for example 0.5mm or 1mm it's invisible for naked eye. But if after drilling I send machine to gome position and get home difference then board can be assumed junk. As I say for now I just check coupler's. And Y coupler is burried in machine and the Y axis is problematic one. I got random error in rare case.. maybe 1 error per month. But wan't to know when hit's me. If I make check with dial indicator's then all is ok. As I home machine when clamping work that solution can be just fine. I just wonder why every time I post something here got feedback (that's not good, just use this and .., you don't need that.. etc etc...) and near none gave solution? Seem's that I'm not alone. The Bernhard Kubicek write nice filter option and was included in git and working few days after that was cripled and doesn't work any more. The problem is posted but noone wan't to correct.

Re: [Emc-users] Homming error
Jan de Kruyf pravi: Oh boy am I truly glad I am not a statistic! So the solution to the statistical dilemma is to put a mark on the shaft and bearing housing. Since we know how many mm the table moves per steppermotorrevolution we travel a multiple of that distance And the stepper shaft will be in exactly the same position on either end of the travel if all is right. Jan de Kruyf. Correct. I do that. But to do that in Y axes I need a loot of digging under bellow to se the bearing. I'm shure that few lines of code can make beter solution. ...just can't do as my knowledge is limited in this area and I (unsucesful) bother other people.

Re: [Emc-users] Homming error
Alex Joni pravi: I just wonder why every time I post something here got feedback (that's not good, just use this and .., you don't need that.. etc etc...) and near none gave solution? You asked for a way to test your axis, and got 3 solutions: Maybe that is the problem. I didn't ask for solution. (My english is not so good so maybe I ask by mystake.) I propose solution. The software solution to just show message with home difference when homing is done. (just need something like in basic Print X offset ,current_machine_position - machine_home_position just before setting home position before after homing axis. (of course for each axis when homed) * use a dial indicator Not good. The error is to rare * use the home switch for probing How to do that if home is limit too? * mark the coupler and watch the position change That's work. The problem all thing is under bellow and it's not practical. If you don't like any of the solutions, then I don't see why anyone is to blame. I don't want to blame anyone. Seem's that I'm not alone. The Bernhard Kubicek write nice filter option and was included in git and working few days after that was cripled and doesn't work any more. The problem is posted but noone wan't to correct. I am not sure of what issue you are talking about, also not about where it is posted. Bugreports get reported here, where I couldn't find anything: http://sourceforge.net/tracker/?group_id=6744atid=106744 As I remember it's posted on linuxcnc forum and emc-developers group. And when I do git pull I got that filter menu to work. few day's lather the filter menu dissapear. bkubicek provided zip.file as response all is on the linux cnc forum. *http://tinyurl.com/y9u5yoh *After patch then menu again works but next git pull kill that. If you want to help resolving such an issue, it really helps to provide further information (then it gets sorted faster): * when the original patch was added, * when it stopped working, * a patch that fixes the issue (either patch or a pull address from your repo where it's fixed). It's all posted at *http://tinyurl.com/y9u5yoh *Seem's bad idea to have two locations for that. I like forum but the response is low. For developing related things the devel mailing list is probably more appropriate. Best regards, Alex I like EMC2 but has filling that 'developers' send's homemade machine's and hobby operator in background with their wishes. I just can't bet it why the targeting big commercial machines with GPL software more than hobby one? em I missing something?!?
