Re: [Emc-users] Strange MDI.
This is a feature of git.
Git wants strict white space, but somehow the patch generation does not
always give
strict whitespace
The solution for me is to extract the patch from the mail and apply it
manually with
patch -l or --ignore-whitespace. (see the patch manpage)

improve behavior of MDI O-calls
Bad things happen when the motion id is zero. This could frequently
happen when doing O-calls from MDI, because the motion ids for an MDI
start at pseudoMdiLineNumber and increase for each executed motion
(? line?) in the subroutine. For instance, if pseudoMdiLineNumber
was
-7, then executing an O-call with 8 or more lines of motion would
issue
a motion with ID 0.

The Keling motors have VERY light rotors, and so I added just a little mass to the motor by mounting a small shaft extension, and it helped quite a bit. I would assume this is a lot less angular momentum than even a small leadscrew. I also had a customer who was experimenting with a very high acceleration machine, and I believe he will eventually abandon the CUI encoders. He was accelerating at something like 1 rad/sec^2, which is really high acceleration, though. Currently, he has cut the acceleration rates to prevent missing counts. Looks like you've already done the research which my snoopy mind just thought prudent. Grateful thanks for the practical insight into the stability limits. _Where_ it would become a problem is what I couldn't guess from that datasheet.

I have a general question about the throughput of EMC2 and what determines it. I friend is using nurb modeling to describe the shapes that he has to mill in soft material. So far he has had disappointing results using EMC2 in that the processing of the large gcode files with many short vectors and the resulting cutting speed is too low. For most cutting moves the programmed speed of the axes is not reached in these applications. Jogging speeds on the machine is fine. Where does the problem lie? In playing with parameters such as base_thread, we found that these have some influence on the troughput and cutting speed. The processing power and latency of the PC also comes into play. It seems that careful tuning and balancing of some parameters is required. The problem is to know which ones will improve the situation best. The steppers are currently driven via the parallel ports.

If you have fast jog that doesn't be equal to fast cut speed. If you have bad acceleration for example to accelerate to max speed when move 5mm then all segments shorter than 10mm can't use max speed of machine. If you use G64 then machine will try to keep speed up but in that case it's not possible to trace exact path.

In a blend that is an exact reversal, this causes the | total axis acceleration to equal the inifile MAX_ACCELERATION. In other | cases, the actual machine acceleration is somewhat less than the inifile | acceleration | | To keep up feed rate, the move must be longer than the distance it takes | to accelerate from 0 to the desired feed rate and then stop again. | Using A as 1/2 the inifile MAX_ACCELERATION and F as the feed rate | *in units per second*, the acceleration time is | ta = F/A | and the acceleration distance is | da = (1/2) * F * ta | the deceleration time and distance are the same, making the critical | distance | d = da + dd = 2*da = F^2 / A. | | For example, for a feed rate of 1 inch per second and an acceleration of | 10 inch/sec^2, the critical distance is 1^2 / 10 = .1 inch.

Your method of obtaining the patch, copy-paste perhaps, contaminated the
patch with trailing whitespace after the text of the patch. Call it back
into your editor of choice, and if vim have it search for ' ', which will
highlight all the spaces. Delete any that are at or beyond the right end of

The keystrokes would be / which will show a line at the bottom of the screen,
then hit ' space 'enter. That will show all spaces. I have a permanent
setting in my copy that shows them by default, but only those which have a

Re: [Emc-users] Emc-gcode throughput
On Thursday 04 March 2010, Rudy du Preez wrote: I have a general question about the throughput of EMC2 and what determines it. I friend is using nurb modeling to describe the shapes that he has to mill in soft material. So far he has had disappointing results using EMC2 in that the processing of the large gcode files with many short vectors and the resulting cutting speed is too low. For most cutting moves the programmed speed of the axes is not reached in these applications. Jogging speeds on the machine is fine. Where does the problem lie? In playing with parameters such as base_thread, we found that these have some influence on the troughput and cutting speed. The processing power and latency of the PC also comes into play. It seems that careful tuning and balancing of some parameters is required. The problem is to know which ones will improve the situation best. The steppers are currently driven via the parallel ports. A MESA 5i20 card is planned to replace this. Has anybody been working on the limited throughput situation? Rudy I don't know if there is a one true way to attack this. I run steppers too, and found quite some time back that if I were willing to give up on acceleration and use a gentler accel setting, the top speed achievable was considerably higher. However corner blending considerations will then slow it down because of the gentler accelerations being used. Without some very strong, low inertia servo's, my method seems to be the best for my work, where I often cut one-sie's, and may spend a day cutting air before actually making the part, but once the mill starts throwing chips, the part is generally usable. YMMV of course. If, OTOH, your cutting speed is limited by available spindle power and rpms, as mine is, one might want to up the accel's and give away top speed. You can, for the most part, reverse a nema 23 stepper that isn't moving a 20 tpi screw at more than a couple of inches/minute very quickly, but you cannot extend that violent an accel to more than that same couple of ipm without encountering a stall. And there goes that part, its usually wrecked. I've had it dancing on the table a few times, but not now, and its much more dependable this way. -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

for an MDI

They are Direct PWM Brushless DC Servo Drives Model# BD30A8. The datasheet can be read at http://www.a-m-c.com/download/datasheet/bd30a8.pdf . I talked to their tech support and there is no current loop or velocity loop in the drive. They told me the PWM signal directly controls the amount of time the MOSFETs are turned on. If it was a brushed DC motor, I understand that the PWM duty cycle would have a linear relationship to the average voltage and hence average speed of the motor, but since it's a brushless DC motor, I don't understand if that same relationship holds or not. AMC has instructions on their web site (little hard to find the right one) on how to tune the servo drive itself. Are you sure the drive is set right for velocity mode? If you look up the pdf he links to above, it is clear this is NOT inherently a servo amplifier, it is just a PWM amplifier, with no internal loop other than the current limit. There is no tach input, no encoder input, other than PWM from the controller. Therefore, other than setting the current limit, there is no tuning that can be done. I make a very similar servo amp, and maybe I shouldn't call it a servo amp, as it has no inherent loop, either. The OP's last question, yes, there is still an approximate linear relation between PWM duty cycle and speed. The motor's resistance throws it off a little, speed will drop slightly under load. Tuning of such drive systems is a bit different than on velocity servo systems, and the inherent stability is less. You don't want to turn up gain until you have wiggles, you want to tune first for stability, then use FF1 and FF2 to reduce following error. See my page on servo tuning for these types of servos at : http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?PWM_Servo_Amplifiers Jon Thanks for the link to your servo tuning page, I will play with the PID settings to see if I can tune for stability first and then add in the FF1 and FF2 as you suggest.

I did some tests a while back, on a 600 MHz Pentium III computer. I made a 2 diameter circle in 10,000 line segments. With the default smoothing, it took 250 seconds to execute. With the smoothing parameter set with G64 P0.0005 (meaning an error tolerance of 0.0005 is acceptable) this program runs in 17 seconds. At that rate, it is doing 10,000 blocks in 17 seconds or 588 G-code blocks a second. That is with a fairly slow computer by today's standards, too! I think I later got it down to 13 seconds, or 769 blocks/sec. These tests were done on a true servo system using my PWM controller board and servo amps. So, there was no BASE_THREAD task in the system, and no step pulses anywhere. I think if you need more than 1000 blocks/second, you need to examine how you are generating your G-code and see if it can be optimized. Assuming 0.001 vector segments, you could move at on inch/second while following any arbitrary curve that doesn't exceed your machine's acceleration limits.

A LOT of people don't know about the G64 P option until they ask, then they are amazed! Jon -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

Re: [Emc-users] Strange MDI.
Jeff Epler pravi:
Which version of emc are you testing with? This behavior is buggy in
2.3, but in v2.4_branch and master there's a change that is intended to
improve or fix this problem:
commit 314f3aa2d90e5ec1f7840166f3e0ad11a9fbc0a6
Author: Jeff Epler jep...@unpythonic.net
Date: Wed Jan 27 08:16:47 2010 -0600
improve behavior of MDI O-calls
Bad things happen when the motion id is zero. This could frequently
happen when doing O-calls from MDI, because the motion ids for an MDI
start at pseudoMdiLineNumber and increase for each executed motion
(? line?) in the subroutine. For instance, if pseudoMdiLineNumber was
-7, then executing an O-call with 8 or more lines of motion would issue
a motion with ID 0.

I can't apply patch. Seems that we have different version.
I'm sure there is no whitespace and line termination is linux style.
Can you send entire emctaskmain.cc?
