I posted a question a while back and I’m still having problems with printing. I’ve used Luban, Prusa and a couple of other slicers so its not the slicer. The problem is, I start a print and it does fine for a while. But after it gets a little talker on the bed either the nozzle or the sensor catches an edge and pulls it away from the rest of the model. Its grabbed it hard enough to slide the magnetic bed down on the printer. I did adjust the sensor once using a credit card from a tutorial that someone sent me (can’t find it now). Any ideas? Pic included.
I think your edges lift up because of not optimal adhension. Try using a brim or other fixes against warping.
Looks also that levelling is bad there. Did you just tried to move it to another place and bed and print there?
