Winner winner chicken dinner! This is EXACTLY what happened. I reprinted again after tightening belts, fixing bed wobble, and re-leveling, and kept a closer eye on it this time. The nozzle was indeed catching on that “Y” support due to the edge curling up. Wasnt enough to kill the print this time, but enough to make me nervous…
Ironically, the thing I’m printing is an all-in-one case so that I can segregate the PSU, main board, pi, and controls from the printer itself to enclose it and have better temp control!
