Re: [Emc-users] Mesa counter card?
The issue with sharing encoder signals with both the Gecko servo driver and the PC comes from the fact that the step and direction signals into the Gecko are optically isolated and the encoder and its signal exist on the other side of the isolation barrier. Maintaining the isolation and sharing the signals will require some additional hardware such as this: http://pico-systems.com/gecko.html Regards, Steve Stallings -Original Message- From: Viesturs Lacis [mailto:viesturs.la...@gmail.com] Sent: Monday, April 09, 2012 4:16 AM To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] Mesa counter card? 2012/4/9 Jeshua Lacock jes...@3dtopo.com: How is that possible?

Ohh, conical fits (I hope that is the correct translation) is the thing we have been discussing in university lately. Answer to Your question is: No. Because You skipped another (and IMHO the most important) factor: specific use-case also applies. What I mean - the angle of taper determines: 1) how well both parts are centered each to other - the smaller angle, the better centering; 2) how much will the distance between bases of both cones change as the surfaces of cones wear off - the larger the angle, the smaller the distance, tolerances on each cone also will increase the tolerance of the fit dimensions for smaller cone angle values; So larger angle improves one, the smaller angle improves the other, so the optimum value lies somewhere inbetween, changing in different situations. That is why there is not the one and only answer (which is also my answer to Your original question). The way I see it now is that the load and material will determine mostly the diameter (and length) of the taper, but the application of particular mechanism (required precision of assembly etc) is the main factor to determine the angle value. Viesturs Nice argument as far as it goes, Viesturs, but it doesn't address what I was taught lo these many years ago by a practicing machinist and which I find echoed in my Machinery's Handbook. He divided the world of tapers into two classes: self-holding and self-releasing. The self-holding tapers have small enough angles of taper for friction along the tapered surface of the joint to reliably resist the torque transmitted from the tool. That same friction makes it difficult to release the taper from its socket. The self-releasing tapers have large enough angles of taper to allow easy removal but require some other means to lock the taper in place so it won't slip when torque is applied. Presumably only the self-holding tapers would be subject to the kind of wear you mention in 2). I suspect the differences within this class were due as much to the need to work around patents as to any thought of optimization. As for the discussion about the varying angles of taper on the various Morse tapers, concensus of the sources I read is that Morse just wasn't that good with his metrology. Once a mistake is propogated into practice through industrial standards, it takes on a life of its own. Regards, Kent -- For Developers, A Lot Can Happen In A Second.

[Emc-users] Lube Pump Duty Cycle...
I had previously tied my oil pump to the run signal on my VFD, so when the machine was running, lube pump was running. The lube pump works with a cam raising an oiler, then letting the spring/gravity drive the pump to push the oil out. My understanding is that it's pretty common to oil way too much on these bridgeport series 1 BOSSV if you leave the pump running all the time, which has proven to be the case for mine, as my floor will attest. Is there a nice way to do a periodic timer or duty cycle in the hal? It's trivial for me to drive the pump relay with a digital output, then I can tune the pump cam motor duty cycle with 'run' to keep it running automatically, but not quite so much...

You can't really run them at any speed other than their intended speed. It's true you could turn them on for a few minutes and off for a few minutes, though, with a timer in ladder.

Re: [Emc-users] Lube Pump Duty Cycle...
That is about 4 rungs of ladder in Classic ladder. Two timers, one timer times out and starts the second one. When the second timer times out it opens a NC contact that feeds the first timer.So timer 1 times out, starting timer 2 which resets timer1 and the loop continues. Put another run of logic with a NO contact from timer 1 with a NC contact from timer 2 in series driving an output.Change the timer values to vary the output duty cycle. Gotta love ladder for simple tasks like that. :-) Dave On 4/9/2012 11:56 AM, John Murphy wrote: I had previously tied my oil pump to the run signal on my VFD, so when the machine was running, lube pump was running.

[Emc-users] Hal_parport and EPP
I am throwing this out as I have run across a few people that have had issues with EPP mode and the printer port. Now onboard parallel ports can usually bet set to epp mode in the bios. Onboard printer ports usually require some sort of utillity to put them into EPP mode. Now if I remember correctly - there was some issues a few months ago with EPP mode and some intel atom boards. Now again - if I recall correctly - the parallel port code for the mesa 7i43 was modified so that it would force the parallel port into EPP mode. (if it could) Now - could this code be added to the hal_parport as an option? something like loadrt hal_parport cfg=0x278 0x378 in 0x20A0 out epp I have not looked yet (and don't know if I can figure it out) but I thought if someone felt ambitious...

The encoders are connected to the Geckos, not through the parallel port I do not understand, what exactly is not clear to You :) AFAIK Gecko drives will need the encoder signal for them to function, so each encoder signal will have to be splitted/doubled/copied to both PC and Gecko drive. Hi Viesturs, Well OK, that was never explained to me. You were saying that perhaps no rewiring would be required, and Peter was saying that the encoders would be wired to the pins of the 5i22, but no one ever told me that they would have to be wired to *booth*. I have stated this already, but it would have been immensely helpful if I could see a simple schematic. I am a bit surprised Peter or Mesa hasn't provided one. When I joined this mailing list, one of the things I learned, is that proper formulation of question considerably increases the chance of receiving an answer :) Please, be as specific as possible, do not be afraid of sharing details. For example, schematics of what exactly do You mean? How to split the encoder signal to feed in two devices - Gecko drive and PC? Or how exactly connect that PC signal to Mesa board? I would like to see a diagram of how to connect the Geckos / encoders to the Mesa card. The first one might get tricky, just like Steve mentioned, and I also think (do not rely on my opinion as I am only beginner with electronics) that additional hardware will be needed for splitting the encoder signal. I need a good understanding of things like this before I can feel comfortable with going ahead with the Mesa card. I am likely even more of a beginner. The second one is brain-dead easy - take GND of the incoming signal and connect to GND of appropriate gpio pin on Mesa card and the same for the signal lead - connect it to appropriate gpio input pin. At this point, the Pico card is looking more appealing to me. Even though I would have to completely rewire everything, at least they have a schematic so I would have a clue what I was doing. From the way You wrote Your first message I understand that You already have a working system with encoder signal going also to PC: 2012/4/6 Jeshua Lacock jes...@3dtopo.com: My Z axis is about 10,000 lines per inch, so it uses up my available bandwidth really fast. Right now I have the Z's max speed set to a mere 3 inches per sec. My Y is 24 inches per sec, and X is 10 inches per sec. That uses up my available 71khz. So, I understand that something like Mesa's 4I30 4 channel quadrature counter card will allow me much more bandwidth to run my servos faster. What kind of 10,000 lines per inch are You talking about, if that is not encoder signal? It could be also step signal, but encoders were the only thing discussed in that message... Could You, please, expand on what exactly You have there? Where are encoders currently connected? As I have stated, the encoders are currently connected to the Geckos. Ok, great! Then could You, please, explain in a lot more detail, what is that 1 lines per inch bandwidth You were talking about? The way I initially understood this: there are 10K pulses from encoder on 1 inch travel and exceeding the velocities, mentioned in Your first post, would simply exceed the LinuxCNC's capability to read them on parport. Since there are no encoder signals on parport, I see that I have been totally wrong. I am pretty much a complete noob on this kind of stuff. Perhaps my understanding is completely wrong. All I know is I only have enough pulse bandwidth to run my servos quite slow. I thought this was based on how fast my computer can send pulses to the Geckos.

I have never hooked mine up because inside the box there is the standard manual oiler handle and a clock motor. I use the manual handle. I vaguely remember being able to change the timing on the clock motor, but it's been a long time. Even with just doing it manually on occasion, I still get oil overflow, particularly in the head.

I think the missing information here is that you are probably using a step-dir servo drive rather than open-loop steppers or servos with LinuxCNC closing the loop. If that is the case, then I am not sure that there is any need to connect the encoders to the PCI card. I _think_ that the G540 firmware for the 5i25 emulates the 8(?) ground pins in a parport, which seems to waste some potentially useful IO. This matters less with a second header for the other 25 pins which I think are GPIO in that config. If the G320(?) has an f-error output then using that achieves much the same result as wiring the encoders back to LinuxCNC. -- For Developers, A Lot Can Happen In A Second.

If the drive is set to 1 pulses per inch and you are using software step generation then a typical base-thread rate of 30,000nS should let you move at 3 inches per second. Using hardware pulse generation you should be able to increase this, as long as the drive system can cope. I suspect the confusion comes from the subject line referring to counting rather than pulse generation. The Mesa 5i25 looks like a parallel port card and (in the G540 configuration) you wire it like a parallel port card. It isn't a huge problem to make a custom DB25 cable to adapt the pinouts if required.

[Emc-users] EMC with MaxNC OL?
Hi, I have an old Max-NC 10 (called Max-NC OL these days) that I used to run on a DOS-based PC about a decade ago. Life happened for a decade, but I've recently dusted it off and would like to put it back in operation. The DOS-based PC that I had is kaputs, my paper documentation (in the blue paper binder) is gone, and I don't have a floppy + DOS-based PC to run on. I think I can get my hands on some parallel ports, though. Are there anyone on this list that is currently running MAX-NC in open-loop quadrature mode with EMC that might be willing to help get me back into operation?

Re: [Emc-users] Hal_parport and EPP
EPP mode is a completely different way of using the pins of the parport than the regular SPP mode. In SPP, you have programmatic control over the values on the output pins, and you can read all the input pins. In EPP, those pins are driven by an additional piece of logic in the parport controller. The driver software asks the EPP controller to read and write addresses on the EPP bus, and the controller twiddles the pins to implement the software's request, according to the datalink protocol described by the EPP spec. So in order to do anything interesting/useful with the EPP port, you need a second driver that knows what registers to read and write on the device on the EPP bus. Simply switching the port to EPP mode doesn't accomplish anything. Maybe i'm missing something in your request?

If that is the case, then I am not sure that there is any need to connect the encoders to the PCI card. Thanks Andy. I guess the problem is I don't know all the terminology. Yes, I guess that is correct. I assume the 'open-loop steppers or servos with LinuxCNC closing the loop' is the best setup? For instance, that would allow the fastest control, and double as a DRO when the power to the drives are off, correct? In which case, I don't mind rewiring the encoders. I just want whatever is best. I _think_ that the G540 firmware for the 5i25 emulates the 8(?) ground pins in a parport, which seems to waste some potentially useful IO. This matters less with a second header for the other 25 pins which I think are GPIO in that config. If the G320(?) has an f-error output then using that achieves much the same result as wiring the encoders back to LinuxCNC. I think you lost me again. :D Best, Jeshua Lacock Founder/Engineer 3DTOPO Incorporated http://3DTOPO.com Phone: 208.462.4171 -- Better than sec?

I thought this was based on how fast my computer can send pulses to the Geckos. If the drive is set to 1 pulses per inch and you are using software step generation then a typical base-thread rate of 30,000nS should let you move at 3 inches per second. Using hardware pulse generation you should be able to increase this, as long as the drive system can cope. Yes, the drive system should cope with much faster. Of course, I will need to test it to see what speed makes it fault. I suspect the confusion comes from the subject line referring to counting rather than pulse generation. Honestly, I really do not understand exactly how the system even works. I just knew that the axis that is geared down the most takes the most bandwidth to run (the 'Pulse rate at max speed' figure reported on the Stepconf Wizard). So I had assumed that it was based on the encoder resolution. Since the encoders are connected to the Gecko - I honestly don't know what the limitation is other than I assume that it is an issue with how fast the system can issue pulses to the Gecko. In other words, if issuing pulses to the Gecko was not a bottleneck, how fast can the Geckos count the encoder lines - as fast as needed? The Mesa 5i25 looks like a parallel port card and (in the G540 configuration) you wire it like a parallel port card. It isn't a huge problem to make a custom DB25 cable to adapt the pinouts if required. (In other configurations it can be nothing like a parallel port, and you can hook 384 lines of IO to it, or directly connect 16 30A servo drives) Sounds good. I guess I am still confused. For a open-loop servos with LinuxCNC closing the loop setup, I guess I would connect the encoders straight to the pins of the 5i22? Would they still need to be split the encoder signals and go to both the 5i22 pins and the Geckos? Peter/Mesa if you are reading this: I really want to order a card from you - last week. ;) Can you please provide me a very quick and crude wiring diagram?

Re: [Emc-users] Hal_parport and EPP
This is how I understand it also. Some have 'fixed' this issue by adding pull up resistors on certain pins. If the port was set to EPP mode - this would not be needed.

Yes, apparently when the port is in ECP mode the voltage is not pulled up high enough for the charge pump output from the PC to be recognized by the G540. I think the G540 would benefit from from pull up resistors on the input lines. Dave -- Better than sec? Nothing is better than sec when it comes to monitoring Big Data applications.

[Emc-users] User Suggestions
I absolutely love LinuxCNC. I am running 2.5.0 now. Here are a few suggestions that I think will make it even better. I think most of them would be fairly trivial to implement. 1. I would love to see a percent of the tool paths remaining. 2. It would be nice if the on screen tool was a different color than the tool paths. Maybe a bit larger too. It is just really difficult to see sometimes. 3. I would love to have the option to make the 3D window full screen (maybe on a 2nd monitor too). 4. An option to not clear out the (red) tool path that has been done. 5. Some simple G-Code tools. Like rotate 90 degrees and scale.

Yes, that is what my Gecko Interface does, the encoders are powered from the Gecko interface, send signals to the Universal Stepper Controller, and also makes an opto-isolated copy for the Gecko 320 drives. It also watches the fault signal on the G320s and powers them on and off when going in and out of E-stop mode. By including LinuxCNC in the servo loop, you can get tighter position control in some cases. You also can use Halscope to know what the following error is under various conditions. Without that feedback to the computer, all you know is that following error is less than the Gecko 320's 128-count limit. That can be a lot of error, depending on encoder resolution and the drive mechanics. On Apr 9, 2012, at 3:40 PM, Andy Pugh wrote: If the G320(?) has an f-error output then using that achieves much the same result as wiring the encoders back to LinuxCNC. Well, no. The fixed error limit on the G320 can be unacceptable in some cases. For instance, assume a 500 cycle/rev encoder on a motor directly driving a 5 TPI leadscrew. In quadrature, you get 2000 counts from the encoder x 5 TPI gives 1 counts/inch. 128 counts equals 12.8 mils or .0128 which is a lot of error. That's just one example, although fairly typical numbers. With a lower resolution encoder or a coarser leadscrew, it would be worse. LinuxCNC provides a sliding scale following error limit, where higher errors are allowed at higher speeds. So, you can set it to tolerate only a small error at cutting speeds, but a larger error at rapid traverse speed. The G320 can't do that. Also, you get an adjustable I term in the PID, plus FF1 and FF2 to help reduce following errors. Jon -- Better than sec? Nothing is better than sec when it comes to monitoring Big Data applications.
