So frustrated… printed about half of my parts in petg and was printing the carriage… about halfway through, Marlin crashed and restarted. Restarted the print, and it did it again. The second time, I forgot to turn the heat on before homing and it pulled the bed out of whack. Got that sorted, releveled the bed, and printed the carriage over usb. Next thing I went to print (xy tensioners), bed was out of level again. Re-leveled the bed and now 've been trying to resume printing for three days and the petg won’t stick to anything but the nozzle regardless of z height. AAARGH!
Sorry had to vent
