#Needhelp Hi guys, I'm having trouble with my print. The bed seems fine; this design has a 3mm raft, and the adhesion of the raft and the first few layers is good, but it starts warping in the upper layers. I've already calibrated the bed, and the extruder isn't clogged. I don't know what's wrong because I printed a whole bed before, and it came out perfectly. Any help?
