Hello everyone! I just got my M2 assembled and tested last night. Everything works well so far, except that when I was jogging along Z axis, it accidentally hit the limit at the bottom, and the Z stepper motor seemed skipping gears and made some loud grinding noise. I stopped the machine immediately after that. Would this cause any damage to the leadscrew and the Z motor? Thanks!
I was hoping there is a mechanism in stepper motors, when there is excessive force applied, it just skips without causing any damage. I did a sample print after that and it seems to be working fine, I'll make sure it won't happen again!
It does no damage at all. There is no connection between the all thread shaft and the stepper. The all thread just has the motor's rotor loctited onto the end. The rotor makes no connection to the outer case or windings of the motor at all. The noise is just the magnets slipping
