Y-AXIS stutters when initializing

3 xxl: when connecting to machine and then initialize, my machine travels on the X-axis normally. When traveling on the Y-axis it “stutters” along until it gets near the end and stops travelling, but “stutters” in place until I disconnect the CNC. I’ve cleaned the tracks and tightened the belts as needed.

Possible causes include:

  • miswired wiring extensions or motors
  • maladjusted or bad homing switch

For what it’s worth, we had the exact same issue. After banging my head on the wall for a few hours, we discovered that one of the connectors (that plugged into one of the Y-axis motors) had a lose wire in it. It must of came that way. We had just finished putting together our Shapeoko 4 XXL.

Anyways, we pushed the loose cable back up into the connector, and everything works smoothly. Not sure how I’m going to fix this long term, but it works today.
