I just finished building my BigBox, and during the magical printing of the 3D Benchy, I always get level shifting around layer 50. Does anyone know what can cause this?
Torque stall maybe? Hard to say without a picture or knowing which direction it shifted in. Have you tuned your stepper drivers?
It always skips in the Y-Axis direction. Stepper motor voltage is: 0.591v. X and Z axis are working perfect.
I found the issue. The stepper-motor driver was dodgy... Replaced it with a DRV8825 I had laying around, and now it's a very happy BigBox
