While in middle of a time-sensitive project it seems as if one of my step motors glitched. As my gantry jogged to a position and slowing down one of the step motors made somewhat of a ratchet sound. I check the last cut and my Y was off by .25". I checked motor/gear engagement, key, teeth etc and all is well. Unfortunatley with controller turned on the motors do not lock in sync, I am able to manually move the gantry with some effort... Bad timing. Any input on how to troubleshoot will be greatly appreciated.
