Layers Not Aligning

Post by Katwitch » Sat Nov 22, 2025 12:00 am

Any thoughts on why this is happening? M2 Dual, V4 hot end, 4 corner bed. I just re-leveled the bed and checked all the motor mounts to make sure they're solid. Seems like a lot of variance from layer to layer and the layers don't align perfectly. Image

hard to tell from those photos but there are 2 thing that have caused layer shift on my M2s.
The most common is the glass plate hold-downs are loose and the plate is moving.
The second is that the screws that hold the belt clamp to the bearing and spider are loose on the Bed.
move the bed all the way out and hold the motor pully with your right hand and then try and move the bed in and out, it should not move, if it does take the glass and heater off and tighten the screws. If that fixes it, print a new belt clamp as it will come loose again! just did this a few months ago on one of my M2s
Good luck!
