Hi Jon, You may want to ask Art to have another look. These days there are plug-ins that are written that talk to various type of hardware.

It may be better to leave closed loop out of it altogether, because a lot of people don't really know what it is, and will claim closed loop operation when it really isn't. That's what EMC does with steppers at the moment - putting encoders on stepper motors gives you "traveling limit switches". It may be possible to do adaptive feedrate override, but it's unlikely without special stepper drives. So at the moment, EMC (and everything else) doesn't support closed loop with steppers. >My thinking was that the information could be better, hopefully good >enough, but never perfect. > > Yep - something is better than nothing :) - Steve - This SF.net email is sponsored by: Splunk Inc.

Re: [Emc-users] Desktop CNC Website Information
Peter, I think the idea is to correct the EMC2-related information, since that's what we know about. It would make sense for someone who knows more about Mach to correct that information. I believe I'm the only one of the EMC developers who has ever installed or evaluated Mach, since I'm one of the only ones who actually has a Windows PC :) You could certainly suggest to Art that he or someone there correct the information about their software. Kirk, It might be good to add a "closed loop" column. That probably used to be implicit in the "stepper vs. servo" column, but it isn't any more because of step-to-servo drives like the Geckos. Also, if you could add web support/wiki to the support column, that would be good. There's a typo in the max steps/sec column - the 300 should be 300k (and I think you can get to 12 MHz with the Mesa cards, but don't quote me on that). I wonder if re-wording that column would make sense anyway. The 20k number is for just about anything you could run Linux on - a P2-233 could probably do that. Most modern systems (less than 3-5 years old) should be able to get to 30 KHz with 2.1.7, or 60 KHz with double-freq in 2.2. It's hard to represent everything in 1 square inch in an HTML table ;) Thanks for your efforts. - Steve Peter Homann wrote: >Hi Kirk, > >Nice table. The data for Mach3 is incorrect in many columns.

Re: [Emc-users] Desktop CNC Website Information
Hi Kirk, Nice table. The data for Mach3 is incorrect in many columns. You really need to compare it to the releases version 2.48 as the 1.48 is quite old and out of date. It does 100K steps/sec on the parallel port. Using TCP/IP add on hardware (Gecko G100) it can do 4M step/second. Using USB devices it can do 75K step/sec It can control additional hardware via Modbus, both serial and TCP/IP Controlled axis may be linear or angular Each axis can also have a home switch. I'm not sure but I think that there can be a +limit and a -limit, makeing it 3 switches per axis.

Re: [Emc-users] Desktop CNC Website Information
What is being claimed for Mach is that it can do rigid tapping IF the spindle is a controlled C axis rather than just a free running spindle. Under these conditions any CNC control that can do two axis coordinated motion can do rigid tapping. Rather a special case as most machines owned by hobbyists and small shops do not have the capability to run the spindle as a controlled axis. Tapping using a "compression/extension" holder is possible with most machines even without a controlled spindle. It can be a guessing game with stopping the spindle and accounting for inertia, but lots of folks do it.

Re: [Emc-users] Desktop CNC Website Information
ok - that is not rigid tapping. In rigid tapping - the tap holder is rigid - no movement in or out. Emc2 tracks the spindle thru the reversal and back out using a quadrature encoder with index. At all times the axis motion is synced with the spindle. http://youtube.com/watch?v=JCEwlfJj__A that is a tap held in a Jacobs chuck. (no movement) (and yes - it was done in metal also :)) We wish we would have recorded that.

Mach burns a lot of CPU time to place step pulses where they need to be. it has a regular interrupt, and then checks is any steps are needed before the next interrupt. If so, it puts the CPU into a wait loop until it is time for the next step, and generates the pulse. When higher step rates are needed, it can burn up to 50%, on average, of the available CPU time just in the step generation task. So, it has the ability to time step pulses BETWEEN the regularly scheduled interrupts. This is how Art gets the higher step rates, but it is a tradeoff. I don't think it is such a good idea to play music, and especially surf the web while machining. I do, however run my Pico Systems web server, email & ftp server, etc., as well as my local network router, firewall and domain server all on an EMC distribution, and use the same machine to run EMC on hardware at my test bench. And, it handles that just fine. I don't usually play music or web surf on it, but I do get on the web when doing software updates. Running stepper or servo systems with a little hardware boost greatly reduces the load on the CPU. I had a customer's old system in for some upgrades, and found that a 400 MHz Pentium II is definitely getting to be the minimum performance for a Ubuntu 6.06-based EMC2 system.

Yes, if they use one pulse per rev in a single-channel sensor, then Mach can't know which way the spindle is turning. You have to have a quadrature encoder with index to do it properly. And, you need much more than one pulse per rev so the Z axis can keep up with the rapid speed change when the spindle reverses. Jon - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] Desktop CNC Website Information
I guess the direction (right turn clyde) of this thread in combination with the 20k that was suggested on the web site leads me to jump in. I tested a Semperon pc recently to see how many pulses I could get to. It was able to get to a bit more than 70k. I ran a motor with it. The drive was a Centent 10 microstep running with about 80 volts in. Motor was a NEMA 34 from Keling with nothing hooked to it. The system was able to produce a bit more than 70k PPS. I've got to say that the motor exhibited significant loss of torque at that speed -- about 2100 RPM. I wouldn't want to run a machine tool using steppers with speeds like that. But to make matters worse I switched to a Gecko 210 and 5 microsteps and was able, with real long accel and decel periods to get the motor to more than 4200 RPM. At those speeds it took nearly a minute to stop the motor without loosing steps. The PC was running a full EMC2 with the mini interface and most of the non emc stuff like firefox and gimp showed significant slowdowns. I ran these to prove I could while running the motor. I did not get any reported real time errors and heard no changes in motor noise during the testing. It was fun but I can't imagine the value of that high a step rate unless one were running step and direction into a servo system.

I suspect the main difference is that the Linux systems continues to run normally while EMC2 is operating, which has not been my experience with Mach. When I tried it out on my Athlon 1800, I found that the system slowed to a crawl. System timers were totally screwed up (things like tooltips popping up after 30 seconds instead of 2 seconds), I couldn't run WinAmp - it would skip. I've seen discussions about turning off all sorts of services, tweaking Windows this way and that, etc. to get the best performance out of Mach. I chuckled recently when someone on the Gecko or CCED lists said "I was even able to browse the web when Mach was running, on a P4-3.4GHz". I don't think it's the control of the timer interrupts that makes them different (as Peter Homann suggested), it's the fact that EMC is still sitting on top of a multitasking OS which is still capable of multitasking even while it's running a machine. You could run a web server, play a game, write a thesis, and listen to music while EMC2 is still happily cutting away. All this can be done on a P3-800, without affecting the machine operation (though there will be some reduction in apparent responsiveness on a slower PC). - Steve - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] Desktop CNC Website Information
Hi Dean, I don't know why you are surprised. My understanding is that the Mach pulse generation engine sits under Windows, getting the timing interrupt very early, before windows has a change to waste it. I see no reason why it would not be as good. That said I haven't compared the two. At the moment Mach can now generate step pulses at 100KHz. Cheers, Peter.

Cool. A few changes though: Name: EMC2 Additional Hardware: optional Max Axes: 9 (XYZ linear, ABC angular, UVW linear) stepper/servo: both, simultaneously Number of G-codes: 63 (I looked at interp_internal.hh to see that) Limit Switches: well, this is an interesting one. you get 3 inputs per joint, so there could be 27 switch inputs Tool Setter: There is G-code to set tool lengths from a sensor, but I'm not positive it's "production ready" Tool Changer: Another gray area - there isn't really a software wedge - you'd generally use CL to make a TC work. You have the option of writing a piece of software as well. Digitizing Probe: Probing has been there about since day 1. I think there are some subroutines for probing areas, but I'm not sure. Support: There isn't a forum. There is email and IRC support.
