Title: Consistency
Post by: prototype on March 12, 2012, 10:15:08 PM

I am trying to calibrate my mach3. It is consistently off. It overtravels about. 030 in positive direction and under travels about. 02 in negative direction.

You first need to get the steps per unit correct. Find the correct setting based on going one direction and distance only, make sure you take out any backlash. Then you can check for backlash by doing two opposite moves for that same distance.

Are you using steppers or servos?

Im using servos. Last night I had it running correct in the settings page. But when I went to mdi screen and typed in a motion it way over travelled

I believe its fixed. The breakout boards were interfering with each other. Causing noise I guess. I bypassed one and now its good.
