From 5i25 manual 5V I/O TOLERANCE The FPGA used on the 5I25 has a 4V absolute maximum input voltage specification. To allow interfacing with 5V inputs, the 5I25 has bus switches on all I/O pins. The bus switches work by turning off when the input voltage exceeds a preset threshold. The 5V I/O tolerance option is the default and should normally be left enabled. For high speed applications where only 3.3V maximum signals are present and overshoot clamping is desired, the 5V I/O tolerance option can be disabled. W3 controls the 5V I/O tolerance option. When W3 is on the default UP position, 5V tolerance mode is enabled. When W3 is in the DOWN position, 5V tolerance mode is disabled. Note that W3 controls 5V tolerance on both P2 and P3 I/O connectors. W3 also selects the pull-up resistor voltage, When 5V I/O tolerance mode is selected, the I/O pull-up resistors are powered from 5V. When 5V I/O tolerance mode is disabled, the I/O pull-up resistors are powered with 3.3V.

Peter, greetings Hmm thats a month earlier than the version I get with apt-get install if I type mesaflash --list I get an error saying unrecognized option --list so I think you have an old version Apt-get install insists I am up to date so I totally removed the mesaflash package (with Synaptic) but now cannot find the mesaflash package in any of the repositories I have set up in Synaptic - including LinuxCNC buildbot. So I thought I would try to compile a new one. I downloaded the software for 7i80 from the Anything I/O page of the Mesa website which has an executable but it seems to be a version dated April 2014 so even older. I have not yet compiled that source as it is bedtime but there must be an easy way to get the latest binary version that I am somehow missing. A detailed set of steps would be much appreciated.

Seb - thank you HAL IO pins are strange and apparently very rare beasts which don't map easily in my mind to the wire -- signal analogy.

Re: [Emc-users] In/Out pin on Hostmot2 Encoder component
John, thank you for your elaboration. Two points interleaved below: snip To extend the wire-signal analogy, I think of I/O pins as tri-stateable signals. I don't really get this analogy as there is also a memory hiding somewhere for when everyone it tri-stated. It feels more like a wire with some sort of latch with weak pull-up (and perhaps pull-downs?) on its output. I.e. it remembers the state imposed on it by anything bussed onto it when the driver turns on a strong 3-state buffer They have two possible uses: 1) as a one-wire handshake, where component A asserts the signal to request an action, and component B clears it when the action is done. 2) to allow multiple components to drive a signal signal. #1 is the index-enable case. It could be replaced by a two-wire handshake, but motion and all the encoder drivers would need to make the change at the same time, and it would require changing existing configurations. There is one caveat to that replacement. The existing one-wire handshake works even across thread boundaries. In other words, a component running in one thread (or even in user space) can request an index capture from an encoder driver running in a faster thread, and be assured that the encoder driver will capture the index position once and only once. That is because the very act of acknowleding the request also clears the request. If the handshake was split into two wires, a request and an acknowledge, then the requestor MUST see the acknowledge and remove the request before a second index pulse occurs, or the index position will be captured twice. In our normal configurations, the requestor is motion, and it is running in the same thread as the encoder driver, so this doesn't matter. But it is very handy to be able to test an encoder by manually setting the request and seeing that when an index pulse occurs the request is cleared. If doing things manually, there is a very good chance that two (or more) index pulses will arrive before you manually clear the request. It was actually trying to do a manual test that got me into this trouble. I think one needs a special comp with an IO pin to connect to the index-enable to something like a pyVCP button. Is the fundamental concept we want for REQ not an edge-input? The receiver latches this and clears the latch when the action (e.g. count reset by the index) is performed. The requester then has to see an ACK signal, deal with the data, and eventually drop and re-raise the REQ. #2 is not currently used by LinuxCNC to my knowledge. One example that I had in mind for it was a FAULT or ESTOP signal that could be driven by any of multiple components to force a shutdown, without having to OR together a bunch of individual signals, one from each module. This is more like an open-collector than a tri-state output. Each component that might detect a fault would drive its I/O pin to the faulted state when a fault condition exists, and would not drive it at all otherwise. One component would be responsible for driving the signal to the not faulted state only one time when the user attempts to reset the fault. This wired OR would look neat in the HAL but unless faulting pins (e.g. limit switches) are to be forced to use the mechanism we need an understanding of what an IO pin connected to an input pin does (c.f. a tristated output connected to a TTL input without pull-ups/pull-downs would have an indeterminate value). The limit switch example seems to require making the GPIO pins of Hostmot2 be IO in case they are to be wire-ORed. This seems much more complicated that a multiple input OR - which is perhaps why it is not currently used. Anyhow I think I must code a one-shot, whose output is an IO, to exercise the encoder index-enable input.

[Emc-users] Mixing BLDC and brushed motors
Greetings This is probably a question for PCW but others might know or have dome it. I am looking at a small machine design where two axes will be BLDC motors and one (or perhaps two) brushed DC. The BLDC motors suit a 7i39 very well (interfaced by a 5i20). Are there any problems in using just two phases of another 7i39 to drive the brushed motor? I presume that one would drive, say A, with the desired level (positive or negative) holding inputs B and C at zero - i.e. no bldc component is needed. The ideal card for the brushed motor would be a 7i40. Would it be practicable to have Hostmot2 firmware for both 7i39 and 7i40 co-exist in the 5i20? If so does a BIT file exist with this combination.

Is it possible that you have extra steps due to noises or bad connections PC --- BoB --- Gecko Drive ? Yes, as I said, motor is drifting in particular direction, which may change (not always), if system is restarted, but the direction of drift does not change, once the system is running - if it gradually goes up, then it does so; if down, then it keeps getting deeper. There is no BoB, step/dir signals go directly from 5i23 to Gecko. Two thoughts - sadly neither addressing the direction of drift constant for a given boot symptom: (a) It is not possible to infer if steps are being lost or gained from a series of holes. Noise might give additional steps - but IMO this is unusual - but this might be when going down when holes get deeper or going up when holes get shallower.

Re: [Emc-users] connecting logic components inputs without creating signals
Greetings -Original Message- From: Jeff Epler [mailto:jep...@unpythonic.net] I have written 'anonymous net' support in branch jepler/anonymous-net Here's how I describe the new functionality: halcmd: allow net command to create anonymous nets Anonymous nets are named 'n$0', 'n$1', and so forth. This usage is not ambiguous, because until now it was an error if the first argument of net had the same name as a signal. However, any hal file that explicitly uses signals with names starting 'n$' will need to be rewritten to use a different prefix before it can use anonymous nets. I think this will contribute greatly to the maintainability of HAL files, especially for complex systems with multiple HAL files for operator controls and tool changers. It has always been a problem to me knowing if something lexically remote and unexpected (an input pin of course) is hooked onto a given signal name because of their global nature. One can of course inspect the running system but how much better it is to be able to desk check things too. I am however worried about the disambiguation. I assume you mean: This usage is not ambiguous, because until now it was an error if the first argument of net had the same name as a *pin*. While the system will easily know this, the human reader will not easily discern the situation. Many comps have pins that are seldom used so the human reader will not instantly recognise if an anon-signal construct is intended or not. Is there any reason not to make this explicit by a command like anet (standing for automatic/anon net) which will only have a list of pins (conventionally or perhaps mandatorily) starting with the output pin?

Re: [Emc-users] Crackling motors using Beaglebone
Mark Not Geckos here but a Leadshine 3 phase stepper motor driver. I think John K has covered more bases than I ever could. In essence I see it as the accumulator counting up and down but not overflowing so a step never gets emitted but the sign of the error is changing so Dir follows this.

Re: [Emc-users] Machinekit Gui
Charles, Philipp, Mark- greetings http://www.tormach.com/store/index.php?app=ecomns=prodshowref=30616 It is configured with a geometric speed law on the spring-loaded ring. You can jog at full rapid speed slowing to a crawl allowing touch-off to a tenth very quickly and safely compared with an MPG or keyboard. Nice unit...I forgot about those. Do you have configs available to get it working with LinuxCNC or does it Just Work? It's not clear from the product page if I can just buy one and use it with a generic LinuxCNC install, or if it only works with Tormach machines. I have access to some similar control panels (jog-shuttle with T-Bar and a bunch of buttonsdid I mention my day job is HD video editing equipment?) and it might make for a pretty nifty control: The Contour product is of course aimed at video editing but does CNC very well as it is practically impossible to accidentally move the machine. Joysticks are a bit too easy to knock for my liking. Seb wrote a component that uses the Linux HIDRAW driver to get the button clicks as HAL Booleans; the Ring is encoded as -7 to 7 for the 14 speeds and stop; the inner wheel gives a signed count updated on each click. This is in the current LinuxCNC releases and so Machinekit. man shuttlexpress gets its doc. I have a very simple COMP that translates the ring position number to an arbitrary range of speeds defined by 7 input pins, latches the buttons for axis selection and supports different step sizes. It can be done in HAL but IMO the C is much more transparent. Thus device does not need a Tormach machine tool to be useful. The Tormach version has silk screened labels but is internally the same as the stock unit sold by Contour. Best wishes John Prentice -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.

Re: [Emc-users] Machinekit Gui
Greetings Charles wrote: It looks good, but for some reason the CPU usage on my BeagleBone is around 50%! I don't know if this is specifically BeagleBone related, or perhaps due to the fact that I just pulled the configs/sim/gscreen and share/gscreen/ directories from Master (skipping anything else updated outside these two directory trees). Regardless, it seems responsive enough when I use keyboard jog, so I'll try and get it working with a real configuration and try moving motors. I am working with a custom GUI in GTK2 including Gremlin on my BBB. The following are anecdotal observations. I would love to properly profile the running code bit do not yet see how to use the available tools (e.g. cProfile) (a) Gremlin needs lots of CPU - I don't know whether it is screen rendering without the hardware accelerators that is the culprit. (b) Showing the nicely shaded cylindrical tool is costly. If I cheat, and make it appear a negligible length/diameter one, then CPU drops by about 10% (c) I have GCode display in sourceview widget. If code (e.g. engraving) is very long then moving the active line in this seems very expensive. (d) Data which is display only, e,g, Distance To Go DROs, implemented as labels are much cheaper than general ones that can accept input like the machine-axis DROs. (e) The GUI is surprisingly useable at very low rates of updating the toolpath, G code and even axis DROs. 1 second is OK. This makes significant average CPU savings. The this low rate is tested when running a real machine. The audio/visual feedback from the hardware makes the system feel snappy even though the screen is lagging. Tests with no machine are misleading. A BBB ought to be plenty powerful enough. Perhaps the proper GPU graphics will fix things. It would be nice to design an experiment to dummy out the graphics work that could be done by hardware or to verify in some other way that there are not other bottlenecks.

Re: [Emc-users] Encoder Index Support Survey
Greetings I am very happy with Peter's comments on the handling of Index and polarity. On frequency, my calcs. are like this: Lathe: Spindle speed up to 3500 RPM. Threading and tapping will be slower than this but very handy to have actual spindle speed display of whole range. Encoder at 500 lines (gives 0.18 deg resolution) and easily sourced. A/B pulse train 29.2 kHz though on some encoders Index can be very narrow. In this case, if one does need it, a hardware latch with control by A/B would not be hard. Mill: Potential spindle speed 12,000 RPM. With 500 line encoder = 100 kHz so probably necessary to limit display of actual speed or use 100 line encoder with a software quadrature decoder. I would like to have a driver that presents the data from the one hardware decoder that is visible on the 'bone headers. That would easily do very high speed spindles. 100 line MPG is a walk-in-the-park but nevertheless will be very useful.

Switching away from gremlin (ie: the DRO tab in Axis) restores the keyboard's normal response when jogging. With your updates, do you still see the keyboard lag, or does reducing the load from gremlin help this issue? With slow refresh on Gremlin my keyboard jog response is fine.

Re: [Emc-users] BeagleBone Image Available
Greetings I have run a real machine and made chips with the BBB and MachineKit package. And very impressive and promising it is even with a 750 kB engraving job. Trying to get beyond the basic integration shows my poor Linux fundamentals :=( (a) Having used the bootable SD card I can remove it and boot the original system from the BBB eMMC but other SD cards will not show up under it in a df listing. I wanted to make a new bootable SD to work on while also retaining the known simple configuration that works. Is this change to original system behaviour expected and if so how is it reversible? (b) I am bemused at where the magic numbers connected to steppin and dirpin in HAL come from (e.g. the comment the actual pin used and 0x4c make no sense to me: #P8.43 PRU1.out2 setp blah blah .stepgen.00.steppin 0x4c I have looked for a pattern with this BeBoPrBr example and all the tables including considering the 0x800 bit and the excess 32 coding for PRUs but cannot see any pattern. I want to add another stepgen to drive the machine spindle. The B axis seems in place in the .dts file but what goes in the HAL? (c) Straight Linux problem: I cannot work out how to Mount USB sticks in the running system under XFCE/Thunar except logged in as root. Thunar says Not Permitted and unlike under Gnome you cannot run things like Thunar or medit with sudo from a Terminal. Google was not my friend on this occasion giving lots of recipes in fstab but no explanation of principles. (d) Similarly I can only shutdown/restart Linux by logging out of linuxcnc and logging in a root as the buttons are greyed out when user linuxcnc. (e) finally and this may be a step too brave at present, I wonder if anyone has tries/succeeded to run the filesystem off a USB drive (probably a harddrive) using pivot root. The hope was to get better performance, particularly in development systems as I would like to install some user Comps.

[Emc-users] Making a BBB interface cape - was BeagleBone Image Available
Greetings -Original Message- From: Charles Steinkuehler [mailto:char...@steinkuehler.net] There are far too many pin naming schemes for the BeagleBone, including two new ones used by the LinuxCNC Beaglebone code. Short answer: Read the code (sorry!) Medium answer: The PRU code uses an integer value that equals the kernel GPIO number plus 32 (so that zero means don't twiddle *ANY* pins!). The values are also extended, and what would be the non-existing GPIO bank 4 means Use the PRU direct I/O pins. The hal_bb_gpio pin numbers is: 1xx = P8 2xx = P9 xx = connector pin number Long Answer: I really need to make a blog page about pin numbering. There's some data in Brandon Heller's post about home/limit switches: http://bb-lcnc.blogspot.com/2013/07/adding-homelimit-switches.html http://bb-lcnc.blogspot.com/2013/07/adding-homelimit-switches.html I'll try to get something posted tonight... -- Charles Steinkuehler Thank you for this information. After some code reading the .dts file for the BeBoPr-bridge got me to the existing pinouts for stepping. For new inputs, I need to work through Brandon's stuff on my system. The para: We'll use X-Max, the limit switch closest to the PWM outputs at the edge of the BeBoPr. According to the BeBoPr manual, the BeagleBone black manual (BBB_SRM.pdf pg 80), and tracing the board traces, the X-max input switch is pin 32 on connector 8 and gpio0.11. has me puzzled. I cannot find the BeBoPr manual anywhere on CircuitCo and have not got one (or a Bridge) to trace tracks :-( The .dts file suggests Brandon's numbers are non-Bridge and X-max will be P8-9 (gpio2.5) Finally a detailed question: I notice on the 'scope that the DIR lines have random looking waveforms (around 500 Hz - but different patterns on each axis) after a keyboard jog has stopped. An axis DIR goes quiet (at LO) after a G-code move of the axis. Is this behaviour intentional? If not might it hide a bug on Setup/Hold times of the DIR line - I ask as in another life I have been bitten by the small, but very nasty to find, loss of position errors that invalid timing can produce on some stepper drivers?

I am trying to figure out how to make an adaptor. The ideal thing would have an internal keyway and an external key, but I can't off-hand think of a way to make that with sufficient guarantee of concentricity. The Plan B is a machined sleeve with holes for pegs which can engage both keyways. Not having ever used a horizontal milling arbor, should there be a full-length key? Mine appears to only have one very short key. The arbors I have used typically have a long key going through all the spacers. A short key might wander axially under extended heavy cutting. If you turn the OD and bore the ID of your adaptor then the straightness of the arbor is probably a bigger error than your adaptor's concentricity. I don't think the keys matter that much - unless I misunderstand the question.

We use Stratasys FDM printers in our Mechanical Engineering undergraduate course.

About 10 hours of work including peer reviews and submitting a design history file. www.nottingham.ac.uk/~epzjap1/Misc/HelicalBox.jpg The filament winder uses servo control of thread tension, a 1:4 ratio spur gearbox, all shafts with ball bearings. Each student designs from the ground up and manufactures the parts using CNC milling, FDM and manual machining/fitting. Entire project, including control system, is 60 hours. www.nottingham.ac.uk/~epzjap1/Misc/BernieWinder.jpg So RP allows production of machine elements that actually work and in timescales and costs that fit into a Mech Eng degree programme.

Re: [Emc-users] hal 'net' command puzzler
Gene - greetings As an aside, as many nets are best written on one line, inventing the signal name is tedious. It would suit me to allow a wildcard, * or whatever, as signalname and HAL would invent a unique internal name for its own purposes. John Prentice While that might be kewl, how the heck would us humans trace it? You just see the pins connected together on the line of text. An analogy in our electrical world is that you need wire names (more often numbers in my work) between modules or boards but don't need them inside a unit as the connections are intimate, generally obvious and often very numerous. I know that PCB layout systems generally enforce naming of everything but this too is cumbersome (e.g. for xtal oscillator, compensation RCs tied to a chip) The more names I type the more typos I make - but as I say it is only an aside while we were exploring HAL.

Re: [Emc-users] hal 'net' command puzzler
From: andy pugh bodge...@gmail.com Every net command is followed immediately by a signal name. That is, a name you have chosen yourself, to make sense to you (or to confuse yourself horribly in the future, if you so choose). You can uses the same signal name on as many net commands as you like. But being a signal name it needs to be the first term after the word net Every net command with the same signal name will pass the same value to every HAL pin listed in the command. And that value will be from the one, and only one, output pin that appears in one of the net commands. I use the mental model that the signal is a wire and the signalname defined after net is the heatshrink sleeve printed with its name. The wire loops its way round pins (i.e. terminals) but, as the order of writing does not matter, the HAL is essentially a schematic not a wiring diagram. Of course woebetide the person who wires the outputs of more than one totem pole gate (or push-pull amp) together. HAL gives you an error if you try it and this prompts you to include a selector, or tri-state bus arrangement on the drivers. As an aside, as many nets are best written on one line, inventing the signal name is tedious. It would suit me to allow a wildcard, * or whatever, as signalname and HAL would invent a unique internal name for its own purposes.

Re: [Emc-users] Relay driver not working
Greetings From: andy pugh bodge...@gmail.com A dozen or so shorted I/O lines is unlikely to cause FPGA damage (ask me how I know) My 7i43 survived having _all_ the pins on one connector shorted to GND. It's distressingly easy to do if you crimp the ribbon cable a bit wrong. Apologies if it is too obvious, but some might not have seen this simple IDC cable tester. I test every cable I make now my eyes are not so good. Take a pin header with the required number of pins - one sawn out of a scrap PCB and cleaned up will do. Run a length of bare copper wire along the even pins and solder it to each pin. Plug in the cable to be tested. Connect one probe of a bleeping multimeter to this wire and run the other probe along the odd pins. A bleep will indicate a short which is bound to be between adjacent wires - i.e. odd and even pin. A quicker version that does not identify where the fault is, is to wire the odd pins together and have the meter across the two wires. Of course, open circuits are harder to do but less common in new cables. John Prentice -- For Developers, A Lot Can Happen In A Second. Boundary is the first to Know...and Tell You.

Re: [Emc-users] parsing the current language dialect, and describing as EBNF
From: andy pugh bodge...@gmail.com To: emc-users@lists.sourceforge.net Sent: Monday, February 06, 2012 8:03 AM snip However I see no reason why we shouldn't consider starting from scratch with a new machine-control language, possibly based on Python syntax. I would prefer to see that translated directly into motion commands in LinuxCNC rather than into any sort of G-code, though. However, fun though that might be, I doubt it would reach completion, or gain any sort of market acceptance outside a very small subset of LinuxCNC users, and almost certainly wouldn't expand outside our project. I agree with Andy's last paragraph. There are, however, pursuasive reasons for a change from G-codes if we could allow the machine tool to understand enough about what it is doing to be (self-)adaptive. There is a current example in cutter wear compensation. The machine (if fitted with laser metrology) or operator (with a micrometer) can adjust the control to compensate for a tool that is wearing - no need to re-CAM the part!. Generally though the control dumbly obeys orders (from the CAM) - e.g. executing lots of line or arc segment with no notion they define the wall of a pocket. As we know, trouble comes if G42 comp is on and a sharp internal corner shows up. There has been international work on a project (STEP-NC) that aims to give enough information about the design intent of a part so that the control can optimise finish, metal removal, accuracy, or, WHY depending on the stiffness of the machine, how blunt the tooling is, variations in the workpiece etc. This is very ambitious and I have no idea if it is still active or got stalled but a higher level machining abstraction could make it worth passing on the obvious advantages of the familiar G-codes.

(a) The jog in feedhold really is a significant pain. You do need to move the tool away from the work when milling or turning stringy materials. Even something simple like deep-drilling with pecks can snarl up the tool with swarf. Of course the general solution could be very complex (e.g. if offsets were to be changed while feedheld) but some simple rules would cover a lot of cases without obvious risks to a thinking user. (b) For most practical tapered pipe threads no one will notice the pitch error. On one hand I think it is unusual CNC behaviour in threading (so possible difficulties for CAM users without a special postprocessor).

Run from line is a particularly interesting puzzle, but not directly linked to your question.

Re: [Emc-users] PID BLDC
Viesturs, greetings - Original Message - From: Viesturs Lacis viesturs.la...@gmail.com As I wrote, I was trying to get servo motor turning. I was opening EMC, trying to jog motor, failing, closing EMC, changing some settings in HAL file and then running EMC again to see, if there is improvement. I had made 10 attempts. Sorry this is no help with your 7i43 trouble but when you get it going I have a suggestion to make tuning easier. I wanted to test some very high resolution linear scales to close servo loops. I made the trivial modification to the PID component to change the Gains from Parameters to Input pins and used HAL to wire the gains to scale controls on a pyVCP. I added a unit step button to the VCP. That way you have instant tuning of the PID values and can even rescue an unstable situation by dragging the sliders. I hope you find the 7i43 trouble soon and that this idea might then help.

Re: [Emc-users] Variable axes acceleration
- Original Message - From: Steve Stallings steve...@newsguy.com Accomodating a variable acceleration limit would seem to be fairly complex. Perhaps there is a solution that would offer some of the benefit without as much pain. Since rapid moves are done without cutting loads, perhaps we could have a separate set of acceleration and velocity limits that are used only for rapid moves. This would offer some improvement without a major rewrite of the trajectory planner. Regards, Steve Stallings On a related topic I have wondered if it would be possible to have a second set of following error settings for rapids. I feel in my tuning that I sacrifice rapid performance to avoid errors that really only need to be tight during cutting.

There may be neater and/or easier ways. Please could you amplify that writes direct to an IO pin? I have been reading the source of a few components (from and2 to bldc) but I have not found much documentation on exactly how the magic works. I am not actually convinced that I really know the difference between a component Parameter and a Pin. PID seems to be documented in different places with the gains sometimes called Pins and sometimes Parameters. In a wild moment I wondered about changing the gains to Inputs but am not confident on recompiling components. BTW bldc is driving my motors like a champ. I had to resort to trying all patterns. Looking at the hall outputs and using a battery A-B etc did not find the correct pattern. The other trick that helped was to ignore the encoder (with T parameter) until motor would rotate. There are a lot of things that can be wrong between the patterns and the A/B connections on the encoder!

Re: [Emc-users] On the status of BLDC component and Hostmot2
Andy, greetings There is an SVTP7_7i39 bitfile which I believe should arrive with a apt-get install emc2-firmware (and which you might already have) The current release (2.4.6) has the bldc_hall3 component, but doesn't seem to have the three-phase PWM Hostmot2 function so you will need 2.5 to use the 7i39. I have installed the emc2-firmware package and in the 5i20 folder the changelog for firmware release 0.8 says there is a 5i20/SVTP_7I39.PIN The actual file installed is SVTP6_7I39.PIN. The changelog says there is a ti23/SVTP6_7I39.PIN. I take it that ti23 is a typo for 5i23. Now for some wild guessing on naming. SV starts ever name, TP = three phase, 6 is a version number and 7i39 is the daughter board expected. If 6 is the version then it sounds as though the released firmware is behind the version (SVTP7_7i39) to which you refer. Release was December 19 2010 by Jeff Epler. I have not yet found where the actual bit files (and VHDL stuff) are stored. Any advice/help welcomed - I have so many unknowns that I at least want to start with the latest versions of everything.

[Emc-users] On the status of BLDC component and Hostmot2
Greetings I have an XY stage with Heidenhain linear encoders and BLDC motors on its screws. The encoders have built in interpolation giving a 0.08 micrometre resolution. I have a Mesa 7i39 on its way. There was a lot of BLDC work done by Andy Pugh around the turn of the year but so far as I can see everything is now very quiet. If I pull 2.5-pre and compile it should I have everything needed (including a bitfile for Mesa 5i20)? The motors are Elcom/Pittman Nema 23 frame (5111D008) - So far Google has not helped much! I plan to test initially with a rotary encoder as runaway on the XY table would be nasty. Does anyone have any additional advice?

snip Rather than download/compile, you can install the precompiled package from the buildbot, which is probably easier: http://buildbot.linuxcnc.org/ Do you have Hall sensors on the motors? Andy, greetings Thanks for the suggestion of Buildbot. The motors do have Hall sensors. I thought that I would start gently with trapezoidal drive, then close the position loop with the encoders and finally see what happens to performance using sinusoidal. The encoder resolution is so high (effectively 25,000 counts per rev) that it seems there could be lots of traps. The XY stage is obviously from some semiconductor fab. line, made by Newport, very stiff mechanically. It must have been servo controlled originally though I have no original electronics. Finally a really dumb question. The 7i39 has SENSE A0/A1 and SENSE B0/B1 outputs to FPGA board and these signals are on Pins 4/5 of the encoder interfaces. What are they for?

Creo Elements/Pro is a full CAD/CAM package and has EMC2 compatible output. Right? Igor - pardon me jumping in here Creo Elements/Pro (was Pro|Engineer Wildfire 5.0) will generate good G-code for all sorts of milling up to full 5 axis stuff. It has a generic post processor with a menu driven confguration program to configure the details of the G-code output. This program allows you to define the architecture of your rotary axes - trunnion, wrist etc. For the brave, there are other tools that allow you to control the code in very detailed ways (e.g. FIL) Commercial seats of this product is not cheap and the educational versions are limited in CAM capability. The learning curve is steep. There are many historical GUIs in the software. There is a lot of stuff on U-tube but it mainly relates to Wildfire 4.0 (or earlier) The NC Manufacturing module GUI has changed dramatically for Creo/Elements Pro. Undergraduate students, who use Pro|E CAD regularly, can machine their first part after about 6 hours of study. Workflow for prototyping shops is very good, as the manufacturing model is fully associative with the 3D part modelled in the CAD parts of the package. Change a pocket size or depth, re-run the creation of the CL data and G-code files and it will cut the new part. CAM solutions based in importing IGES are a problem as you often have to redefine all the cutting sequences for the new version of the file. You also get a version of Vericut which gives an accurate preview of machining including possible interference of tool holders with stock or fixturing.

Devils Advocaat Because you are asking for a square corner, and not getting it. You should know that you are going to have a rounded corner, and the G-code should determine what the corner radius should be, not the interpreter. However, it is so long since I used cutter comp that I have forgotten what the actual behaviour is. I can see arguments both ways, but anything which stops folk with braindead postprocessors blaming the EMC2 devs gets my vote :) -- atp Perhaps speaking from ignorance, but my belief was that an inside corner being rounded to tool radius is not warned about, it certainly isn't a gouge - i.e. a cut beyond the programmed face - but that the warning relates to the case of a sequence of short line segments in a corner; when, with limited lookahead, steps would be done which crash the outgoing face of the corner before the planner even knows there is a corner coming up. One probably does not hand code this except by accident or in very odd geometry but CAM is very prone to do it when approximating curves. In the CAM case if one makes the CAM output tool centreline data it has the benefit of knowing all about the geometry so will turn early enough to avoid a gouge. One can still apply wear compensation - the crude requirement becomes that the wear value is small compared with the line segments.

Re: [Emc-users] Lathe ATC integration
- Original Message - From: Chris Radek ch...@timeguy.com snip I admit that I don't quite see how these tool changers are supposed to work. When the stepper backs up against the stop, doesn't it stall and lose position? Is there some kind of feedback available? When you start up, how do you know what position it's in? I have never seen a machine with a tool changer that operates like this. Boxford in UK used this for small and medium sized changers. For an 8 position turret you have a ratchet with 8 teeth and a spring-loaded pawl. Assuming you know where you are now (say tool 2) and each click needs 100 steps. To move to tool 5 you output 330 steps. You now know that ratchet is about 30 steps after a click. Send 40 reverse steps. The stepper stalls, as you say, but you are in the known position for tool 5. Next move to say tool 6 just outputs 130 steps forward and 40 back. John Prentice -- This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?

Re: [Emc-users] threading Z oscillation depends on encoder PPR
Andy Pugh wrote: snip An alternative might be to keep things much as they are, but to have a parameter in the G-code for how much run up it has. It then becomes a somewhat simpler trajectory planner issue to get to the thread start at the right speed next time the index comes round on the unloaded spindle and only then to enter the current position-feedback mode to stay on-pitch and allow for spindle velocity changes. I think that might actually be the essence of how Chris' patch works, though that just waits to get a better spindle speed estimate I think. Greeting to all This may be another data point. Another PC based controller produces pretty decent threads even on a low powered spindle like the Tormach Duality with only one pulse per rev. by not attempting to solve the general problem. The threading code (G32) watches index pulses until it sees several with a consistent timing. That gives the spindle speed and with the requested pitch (F word) gives the Z feed in units/min. Now the Z (and X for tapered threads) trajectory can be planned from the current Z position. On seing the next index the trajectory runs. To get a clean start one cuts a few threads in air over the acceleration period. So there is no exact thread position on the stock - it all depends of the acceleration - but multiple start threads work out fine by keeping the same spindle speed and starting with Z 1/2. 1/3 etc. of a pitch greater. The actual code does a running correction, if the spindle speed droops, effectively by using the feed rate override logic . I think it might be better to recognise a rise too as an overcompensated spindle drive can speed up on taking the cutting load - but that is a detail and was not done as FRO upwards could at one time violate the motor tuning parameters. This is by no means an electronic gearbox but needs no tuning and is surprisingly effective for turning even long threads. John Prentice -- Come build with us!

Re: [Emc-users] Interactive machining
Greetings Steve et al Congrats. on election result (to you and others of course) I'd say that flash, although it's more or less fine for media, has no place in the requirements list for EMC2 :) There are any number of fine programming languages and environments to use for the UI. I'm not sure what you'd use to make a flash presentation on Linux anyway, and I wouldn't want to be beholden to Adobe to make updated versions for my OS (which they don't - I use a 64-bit version of Linux, and they don't seem to like supporting 64-bit OSes on anything but PowerPC macs AFAICS). No, I accept the current problem in a Linux environment but things do change surprisingly quickly sometimes. Flash player penetration is very high in the parallel universe. Reliance on Adobe or any one vendor is unhappy but Sothink and SWiSHMax both offer very capable development environments. On a technical level, I'm not sure what facilities Flash has for actually doing things that aren't media or web-related anyway. It is not the time/place to be dogmatic as I cannot show a demonstration, but there *are* two aspects I think Flash offers (a) A framework for design of very interactive graphic interfaces (e.g. the label for an Axis DRO that opens up to show scaling, offsets applied etc. when it is clicked) integrated with (b) A powerful and well structured script programming language. The difficulty in applying Flash is that the documentation/tutorial material is highly orientated to the web design aspects and the terminology is thus foreign. The ability to instantiate graphics objects, which can be movies, as buttons, text, DROs, etc. with overideable inherited properties is, however, a very powerful tool. On a more general point, we have come to accept heirarchical dialog systems as the norm. So many application program dialogs are modal and we while away our lives clicking OK/Done etc. When I started using Solidworks and Pro/ENGINEER I was blown away by the benefits of the implied OK in Solidworks. As an example, you place a dimension and a panel comes up for entering its properties. This panel has an OK and a Cancel button but if you just click on the sketch then OK is assumed and you can place another dimension. This works wherever there is a reasonable assumption. Where the implication is risky you need a positive confirmation of OK. Pro/E on the other had pendantically wants confirmation at every step (and in Wildfire 2 at least different modules ask for it in different ways and on different parts of the screen). The available computing power seems to offer scope for increased safety and ease of use in HMIs provided the development tools are available. /mini-rant John Prentice - This SF.net email is sponsored by: Splunk Inc.

The nearest I came was keying the standard PDP8 boot loader. I submit one should not contemplate extension of the # parameter mechanism. So what is needed? Probably many things are useful but I suggest two that are different in kind. (a) Interactive CAM. The distinguishing feature is that the result of using such a system is a G-code program or program fragment. There are plenty of exemplars both in commercial machines and PC controllers. In essence one defines the desired cut(s) by choosing from standard operations like pockets, facing, PCD circles, standard panel apertures etc. and/or teaching by recording jogs. Such a system have very little interaction with the control beyond being easy to initiate, have a neat way of loading the generated code and perhaps picking up DROs for teaching. The author of this type of program needs access to tools to implement a GUI for his/her users and the ability to write to a part program file. (b) Interactive machining. Here the distinguishing feature is that the thread of code run by the user actually controls the machine. This allows two things. Firstly the control flow of the user program depends not only on user input but on the machine state (e.g. the tripping of a probe, the input power to the spindle). Secondly it can take place whilst a G-code program is loaded - so is useful for tasks like semi-automatic stock preparation. The author of an Interactive program needs access to tools to present the GUI at the user side, the ability to issue commands to the machine (say in the form of G-code strings) and to read the current state of hardware and software (offset systems, modes, speeds etc). This is a tougher call. head_even_higher These interfaces feel to me to be much like interactive web page designs. Flash (and its support tools) seems to be a strong contender (very powerful graphics - static and dynamic, a form of object orientated programming, surprisingly efficient) although the Linux world seems currently rather deprived on implementation. /head_even_higher/head_above...

While this device is recognized by hal_input, it behaves very oddly--the way it operates is at odds with other similar devices. I don't think this device would be useful with emc without device-specific hacks, and even then it would be problematic. Read on if you'd like a longer explanation. snip I got some good advice from Emc-developers earlier in the year about driving this device but never did manage to get it going with EMC2 because of the sort of strange numbers your test have just shown. However, although I think the hardware is idiosyncratic, it does generate sensible values for buttons, inner wheel and the spring loaded ring under the built-in HID driver of Win Xp - two wrongs make a right do I hear :=) In particular you do get zero reports, For instance, imagine you use the shuttle to jog in one of 8 slow speeds. When you let go of the shuttle, it snaps back to the unreported zero position, but there's no report for that. There's no guarantee it reports 1 either. So you can't tell for a few seconds (until a report of a held position would have arrived) that you've returned the shuttle to home. Do you want your machine to keep jogging for 5 seconds after you stopped? A resounding No!. The jogwheel already isn't very useful due to its small number of reports per revolution (10), and the fact that 1 report out of 256 is lost (what's worse, the lost position will be at varying positions of the spinner since 256 is not a multiple of 12). As a result of this experience, I do not recommend the Shuttle Xpress to anyone who hopes to use it with emc2. I must, however, disagree with this conclusion. If it could be interfaced it would be a valuable jogging tool. If you program the 7 (forward and reverse) speeds of the ring in geometric progression to 100% of rapid speed it turns out to be very ergonomic. You can jog end to end of a big table (or big Z) at high speed and end with a very gentle touch to the time honoured Rizla. The inner wheel is then useful to put on a few thou of cut with a few clicks. I know of people who use the ring speeds for manual machining - say facing off stock with a fly cutter. Two of the devices driving X and Z of a lathe are very good for tool setup work - quicker than conventional MPGs because of the geometric range of speeds - and perfectly usable for manual turning like facing off a length of stock. Now the product is not IP65 protected and would not survive a pallet lifter driven over it but at the price and as it uses no precious I/O pins I believe it is worth the effort of getting it to work.

One does have to beware of what happens to arcs with unequal, say, X and Y factors. Rotation seems to me much more difficult to specify because of jogging and because of work offsets. Does the X jog move the table left and right or in such a way that only the X DRO alters? Is the rotation about 0,0,0 in the current cosys, the G54 cosys or the G53 cosys?

I believe that X (Linux) gets events like a keyboard, so it may work with the input driver, possibly after some modifications. It has 5 basic operations: rotation CW or CCW, button press (and release of course), and rotation CW/CCW while the button is pressed. It's not RT in any case, so it could be used with halui or a GUI, but not as a jogwheel as Andy was wanting. and I believe the encoder is metallic contacts. If you want a very controllable movement for jogging to a touch, rather than one click is a thou, for manual machining it is worth looking at: http://www.contourdesign.com/shuttlepro/shuttlexpress.htm 5 buttons (axis selection?), a spring loaded ring with 7 steps each side of centre (continuous jog at 7 different speeds - make them geometric ratios), a centre jog wheel (coarse steps but fine for the last few thou). I removed my real MPG from a mill in preference for this $60 device . You can whip from and to end of end to end of an axis at full rapid but slow to a kissing touch with great safety. IMO a case of not having to emulate how handles connected to the old racks of TTL controlled machines :=) Not done it with EMC2, but device is a well behaved HID (Vendor Id 0x0B33, Product Id 0x33) so it might not be too hard. Don't bother with the driver that comes with it (Win only I think anyhow). I would send someone $60 to buy a wheel if that got us a HAL module for it (seriously). John Prentice ps its brother Shuttle Pro has more buttons but I don't think I would remember which does what and no easy way to label them :=) - Take Surveys. Earn Cash.

Re: [Emc-users] [Fwd: Jog wheel ?]
Jeff Thanks for this suggestion. It shows the power of such a modular system - I am conditioned by too many special cases :=) I was using EMC2 2.0 under Ubuntu so I decided it would be best to compile Trunk - just completed OK. less on /proc/bus/input/devices has the Shuttle as: I: Bus=0003 Vendor=0b33 Product=0020 Version=0117 N: Name=Contour Design ShuttleXPress P: Phys=usb-:00:1d.1-2/input0 S: Sysfs=/class/input/input6 H: Handlers=mouse2 event5 B: EV=7 B: KEY= 1fff 0 0 0 0 0 0 0 0 B: REL=180 I am struggling with the -KRAL switches and the Input Specification syntax. How does -B for buttons fit in? Could you give me an example of a suitable Input Spec to map my two HID axes and 5 buttons? Similary I am in trouble with the udev. The udev manual pages are too general for me and I cannot see how to relate your SYSFS example in hal_input doc. to the data I have. A bit of hand-holding would be much appreciated. I will post a wiki page for others who expressed interest when I get it going.

How's your Linux and emc expertise level? You should be able to try out this driver with emc 2.1 by copying a few files from the development version: hal_input.py (copy to /usr/bin/hal_input, and chmod +x): http://cvs.linuxcnc.org/cvs/emc2/src/hal/user_comps/hal_input.py?rev=1.11;content-type=text%2Fplain linux_input.py (copy to /usr/lib/python2.4/site-packages/): http://cvs.linuxcnc.org/cvs/emc2/lib/python/linux_event.py?rev=1.5content-type=text/plain There is a manual page here: http://linuxcnc.org/docs/devel/html/man/man1/hal_input.1.html Once you've installed the driver, the trick is to first find out how to give the device proper permissions (section PERMISSIONS AND UDEV in the manual page), and second to find out how to tell hal_input to use that device (section INPUT SPECIFICATION in the manual page) Jeff - Take Surveys.

Re: [Emc-users] Lap Top IBM R51 with EMC2
Have you checked the port address? My R51 did not use 0x378 by default. Be interesting to see how you get on then. I had problems with Mach3 on R51 as the power control features under Windows were much too clever. EMC2 might go well as it is a nice laptop.

Re: [Emc-users] Which cad software?
Roger, greetings rogerb wrote: Could be a little of topic but I'm looking at getting a mini mill for the shop and would like to go from drawing to tools. I run linux on my computer and have win 2000 running under vmware.I have used a few different softwre packages and they seem to suck (turbocad acad,varicad,qcad).I want to use the mini mill to cut patterns so 2d is the easiest to work with for me. Any suggestions are appreciated. Let us assume we want to keep costs down so OneCNC etc. are out. I think this means you need to choose decent CAD and then CAM: (a) I am afraid, professionally, I use Solidworks to model the whole part and then make a drawing of the view corresponding to the 2.5D milling at one setting on the machine. I export this as a DXF. The design intent in the parametric nature of the original model is invaluable in design iterations. The drawing side of Turbocad offers some parametric features too. TurboCADCAM integrates a 2.5D CAM package quite elegantly but it is not robust and crashes really annoy me. The secret of success drawing with Turbo, IMHO, is customizing the toolbars to suit your worflow. It has so many bars with many flyouts that it is hard to use. Customized for 2D engineering drawing it is fine. The problem is you have to learn it before you customize :=) (b) Having got a DXF and this must be clean (i.e. not containing duplicate lines, little gaps in paths etc. - and coming from the solid more or less ensures this) my 2.5D CAM tool is SheetCam (www.sheetcam.com). This is simple but powerful. It will go round a path with inside or outside offsets and leaving holding tabs, cut pocket with islands, drill automatically identifying holes by their diameter and generate code for a reversing tapping head. Above all it is very robust and well supported. Usual disclaimer here for SheetCam although Les Newell is a friend with whom I have worked on various projects. John Prentice - Take Surveys.

[Emc-users] Jogging peripharals was Re: adding 2nd parallel port
Chris If I was making a pendant I'd sure want a jogwheel instead of plus/minus buttons. It takes the same number of inputs and works much (much!) better. I have a real jogwheel but one of these days I'm going to try one of the little toy knob encoders from mouser etc - they're meant to be volume controls or something, but they might still be more useful for jogging than two buttons. The digital pots do work OK for FRO and the like - IMO not enough pulses per rev for MPG jogging. Have a look at: http://www.contourdesign.com/shuttlepro/shuttlexpress.htm It is designed for video editing ($59.95 list in US). USB interface. I have it set up with the spring loaded shuttle ring for continuous jog (it will do different speeds depending on the distance you turn it) and the inner jog wheel does steps. First four buttons select X, Y, Z, A axes. Fifth button cycles the step size (in range 0.1 to 0.0001) Very intuitive and fast for setting up a machine. Not so good for manual machining like you might do with a calibrated 100 click Fanuc MPG. The bad news for this list is that it is on Mach3 ;=) I still have little Linux sys prog experience (and actually not much with USB on Windows) - but the default Windows driver sees it as a standard HID (vendor ID 0xB33, Product 0x32). The Ring value has a range on +/- 7 so gives quite sensitive continuous jog speed control. If someone made a HAL driver for it, it would, I think,be easy to plug into EMC2.
