Using Mach 3 my Z axis drops over time, I have read a million posts and tried a million different software settings to no avail. Does Anyone know of a setting in Mach to set an incremental step increase in one direction? say for every step one direction use 1.1 steps the other direction to compensate for hardware slippage or better yet for every direction change add 1 step. Everything I read applies to motion correcting both directions and not just one way.
