General Mach Discussion / Creeping Y position. Anyone know something else I can try?

« on: August 06, 2008, 02:18:58 PM »

Hi,

I'm hoping that someone more experienced than I am can suggest where to look to solve this problem.

I get a consistent creep of 0.016 on my +Y axis each time the following routine runs. That is, each time I go back to X0Y0, it is 0.016" from X0Y0, in the +Y direction. No problem with the X axis.

I've searched the archives, and I've adjusted the # of pulses on the Y axis, tried variations in Velocity and Accelaeration - haven't had any improvement so far.

I'm running Mach3, the Mini_Combo (steppers) from CandCNC.com, Gecko 203V's.
