Galil / Question about Galil and Mach3 interaction

« on: November 23, 2018, 04:58:05 PM »

Hello,
 Concerning the Galil plugin and the way Mach 3 work together.
1. When you save motor tuning parameters on the Galil board, KD, KP and KI, are these settings used when Mach3 is running, or does the plugin do something else for tuning?
2. Is it possible to edit any part of the Galil plugin?
3. The feed hold function is rather slow to stop the motion. Can this delay be shortened for a faster response?
Thanks, Allen

Galil / Re: Program stalls then continues.

Jeff,
I have not found a solution. I don't see any difference with a change in buffering or any feedrate. I doubt it is in the Galil as I run several Galil controllers and the only one that does this is with Mach.

Galil / Re: Galil 4143 motor not moving

« on: November 14, 2018, 07:41:30 PM »

Hello. Are you using Galil Tools or Galil Suite? Make sure you have the MT command set correctly for motor type. Since you have encoder feedback and can get a position error, check TT and it should read just under 10 indicating the controller is giving analog output command but motor is not responding. Give a MO(x,y,z or whatever axis you have it connected to) then another tt command and the value should drop to zero. moving the motor shaft should still give encoder pulses. Next give the SH (shx, shy, etc). That tells the controller to Servo Here that axis. Servo Here (SHX) means to allow the servo motor t be commanded based on encoder pulses and command signal.
Example as follows:
MT - tells what type of motor is configured
TT - means Tell Torque. This reads the command voltage given to the amp for each axis.
MO - turns the motor off for each axis. (MOX, MOY, MOZ)
Remember to usa all caps.
if I can more help, let me know. Regards, Allen

Galil / Mach-Galil forgetting position

« on: September 06, 2016, 01:18:37 PM »

Hello, I was having trouble yesterday with stopping and not getting to the correct position. Setup is Mach 3, Galil 4163 and the 4.6 Galil plugin. I gave x19 f150 and it travelled for a distance then stopped way short of 19. It did this several times after working correctly for almost 2 hours. I could enter another MDI command for X and it may or may not go to the right place. I tried giving an M5 after entering another long 19" move and it stopped short of 6" and then shut the spindle off. I am sure my DMC4163 is good as I can run loops all day long and it never fails but Mach seems to cause issues. I forgot to mention I have it connected through ethernet. I have played with the plugin settings and even went back to the recommended defaults from the manual. Ant help is greatly appreciated.

Galil / Program stalls then continues.

« on: April 26, 2016, 07:59:32 AM »

Hello, I am having a strange thing happening with my Galil DMC 4163 and Mach3. Sometimes as a program is running, the motion just stops for a few seconds during a move then continues like nothing has happened. Usually not a big deal unless it's during a finish cut where stopping is visible. I am using XP connected through ethernet to my Galil. I would suspect that Mach is giving a zero speed command to Galil at a random point while the computer or Mach thinks about something. To my knowledge of Galil programming, the only way to stop and start motion during a commanded move, is the SP0 (zero speed) command to that axis. I have found no pattern as to when this happens. Has anyone else seen this and does anyone have a method to test or fix it? Thanks for your time, Allen

Galil / Re: Master Slave setup

Andre,
You can set up the Galil for gantry mode and just have Mach give one axis command. Check the Galil plugin you are using for Mach, I don't remember if you can slave from there. Since you're using servos in closed loop with the Galil, I would think it has a better chance of keeping the motors sync'ed due to the encoders feeding back into it.
Good luck.

Galil / Re: DB 26 pin HD breakout boards for half the cost of ones from Galil

« on: March 12, 2015, 08:04:13 AM »

I have those for my 4163. I chose to get 26 pin cables and mount the breakout boards on a separate plate. I didn't really care for the way they hang out on the DMC but cabling them let me mount them flat and much easier to wire and less chance of breaking one.

Galil / Re: Galil DMC-2163 and Encoder Wireing

« on: December 17, 2014, 08:10:37 AM »

If you had an ac drive with encoder inputs, normally the drive would also have an encoder output to go to your controller. In one project I am using DMM Technology drives which use absolute encoders on the motors to drives and then the drives output incremental encoder signals which go to the Galil. Some ac and dc brushless drives use incremental encoders and Hall sensors or resolvers. The Galil can work with almost anything which will output encoder signals.

Galil / Re: Galil DMC-2163 and Encoder Wireing

« on: December 16, 2014, 12:52:51 PM »

Hello,
The Gecko drives are driven by step and direction signals instead of the normal +/-10vdc other amps require. You will need to configure your Galil for step motor operation to the Geckos. Hooking up the encoder signals to the Galil is not necessary. The Gecko will take the step pulses from the Galil and move the motor\encoder the same number of steps. Direction signals are only pulses internal to the drive at the start of a move sequence to determine which way the motor rotates.
The Galil works fine for driving the Gecko servo drives although if you want better low speed torque, you may want to consider stepper motors and drives or gear reduction of your servo motors.
Hope this helps,
Allen

Galil / Help with Tuning issue

« on: November 22, 2014, 11:37:51 AM »

 I have asked this before but never got an answer. Galil DMC2030, 3 axis servo, Galil plug-in V4.4.0.0. Tuning in Galil WSDK motors respond perfectly. Smooth motion, no noise, 1,000,000 AC and DC, BG and JG commands make the motors do exactly what they are supposed to do. But when I go into Mach3, X axis jerks bad. Y is not as bad but certainly a bit more noise than in Galil terminal mode. Z about the same. Changes motor settings on all 3 axes to 120 velocity and 20 accel. I am trying to find out why my PID tuning parameters need to be changed. How is Mach working with the Galil to monitor position? Does Mach send BG commands then leave it up to Galil to complete the move or does it intervene during the move to alter the position and velocity based on Mach's calculations? How would be the best way to tune the servo motors for use with Mach3?
Thanks, Allen
