Hi, I have a formbot 2.4 I have recently built. It’s having issues with the first layer so I went through the z calibrate process. The issue I am seeing is after I do that and then do the absolute move to G0 Z1 it’s more than 0.5mm high. QGL definitely takes a lot of try’s so I would guess I have some Z motion issues. I’m not sure where to start.

Thanks.

My first guess would be Z belt tension is way too loose and/or slipping, could also be related to racked gantry
