WHAT IS BACKLASH AND HOW TO CORRECT IT - MachMotion
1. Move an axis in one direction farther than the maximum possible backlash. (Example .020, hopefully less than that is needed!) 2. Mount a dial indicator and zero it. 3. Move the axis again in the same direction for a specific distance (it doesn't matter how far). 4. Move the axis backwards the same distance.
