General Mach Discussion / Backlash Compensation not affecting axis travel.
« on: November 09, 2010, 01:20:42 PM »
Hi Folks,
I've been searching for a few hours on this forum looking for the problem I have, but none seem to work for me.
I have ~0.004" backlash in the z-axis, but after entering value and restarting Mach3, the milling machine does not respond to the compensation. The values are 'saved', and I have tried different Backlash Speeds, Shuttle Accelerations, axis, and even different compensation numbers.
I have an indicator setup, and step the axis in 0.001" increments, when reversing it takes 4-5 'steps' to register movement. Also the machine is a retrofit, and with previous software I could here extra 'steps' the stepper would take as it reversed, but have not heard that noise, even when trying different compensations values on different axis.
Does the compensation only work when a toolpath is running?
Thanks for your help.
Eric
