Hello,
Im new to the CNC world and Im needing help with runout on my Z-Axis. I have taken it apart 3 times and replaced the stepper motor mount-ball screw bearings. Today I think I have found the problem just don know how to fix it.
As I was trying to tram the head to the Colum with a 1/2 drill rod in the spindle I noticed as I raised the head the test indicator was moving back and forth about .050 . I also could see the ball screw through the opening in the column moving back and forth also. Is this normal or did I miss something in the insulation.
Thanks Anthony L
