Backlash Compensation
Code 127: Calculate X or Z Backlash Constant
Every mechanical system has at least a little backlash or lost motion. It is produced by the small
amount of play between the gibs and ways, and mostly by the accumulative bending or elasticity of
all the parts of the drive train under load. The backlash constant is factory set, but may need to be
adjusted periodically.
1.
Set a .0001-inch dial indicator in the spindle, and touch off on a block or the vise along the
direction (X or Z) you wish to check, or set the backlash constant.
2.
Turn on the ProtoTRAK and at the Main Menu, follow the procedure below precisely:
