Galil / Re: Program stalls then continues.

Allen,
I was wondering if you found the cause for the pausing of your system.  I recently got my machine up and running with MACH4 and Galil  DMC-4143 and have experienced similar behavior.  I believe the problem is more prevelant when I run in > 100% feed override but that may be a coincidence.  Anyway interested to know if you resolved.

Thanks
Jeff

Galil / Re: Should I update the Galil Firmware?

Mark,

I wanted to let you know that I was successful getting my machine up and running well with mach4 and Galil DMC-4143.  First, the Dmc in my system is commanding velocity (analog +/-10vdc) to my servo amplifiers.  The amplifiers execute the analog velocity set point by commanding torque/current to the servos.  I tuned each axis offline until I was happy with the response, shooting for critically damped.  The acceleration terms in the servo amps are set very high or effectively not limiting.  The Galil plugin is also set to 30,000,000 Accel/decel, or effectively non limiting.  The term used to set accel/decel is in the mach4 config / Mach /motors / tab.  I used a low Accel term of 100 units/sec^2. 
Galil plugin settings

UDP
COMMAND PORT 23
MESSAGE PORT 6001
LINEAR INTERPOLATION
VECTOR TIME CONSTANT 1
VECTOR ACCEL/DECELERATIONS 30,000,000
TIME SLICE 8MS
BUFFER 75MS
TIME INTERVAL 25MS

The time slice, buffer, and time interval needed to be increased on my setup to eliminate communication errors to the Galil Dmc.
I hope this helps.  If you have any questions let me know. 

Good luck,
Kono

Hi AussieBloke,

I recently got my router up and running with Mach4 and Galil DMC 4103.  I was having communication faults with Rev 1.2b.  I sent the controller to Galil for the upgrade to Rev2.0.  The communications faults seem to be gone, however I am having a different issue.  I am experiencing excessive jitter or resonance when running a gcode.
