Hi everyone. My Zenbot was fine for two months. In the last 2 weeks the Z axis was fluttering terribly when I tried to jog with xbox 360 controller.I checking the belts and bolts and everything mechanical, nothing out of place. I switched the cables from the driver to the steppers and found the z axis stepper worked fine when plugged into the x axis cable. I then checked in the motor configs, the z was different than the other two axes so I changed it and it ran flawlessly. Thought it was fixed, then after a few days, the x axis started doing the same thing. This time, I don't see anything off in the motor configs, and after shutting everything down, restarting, I can't get it working.
I would just like to know, what would make the machine just go from working fine to this?
