I have retro fitted a Eumach Mill with new servo drives and the G3 controller and i am having issues with accuracy.
The problem is when the machine is jogged foward with the step buttons and the reversed its losing position. DRO reads correct
I think there is a software issue with the pulsing on change of direction , this sounds like backlash but i have disconnected the motor and watched the motor shalf when jogging back and forward.
if i use the step 0.10 and move forward it moves the requested distance but when you then go backwards 0.10 it moves less then half that and was a really weak move like its acceleration is really slow all sudden. but keep moving again in the same direction 0.10 and it normal again and you can keeping moving again and again in the same direction no issues until you change direction and on the first pulse of the new direction it does again as described above then back to normal no issues.
to prove i wasn't seeing things i wired a mach 4 controller to the same servo motor and did the same commands and there was no problem! so its in the masso controller.
anyone got any thoughts?
regards Sean
