This is a running list of all of the ways I have broken a print. This doesn’t have anything to do with my machine calibration. That’s a whole other post in itself!
-I got a snag in the filament feed which stopped extrusion.
-My heated bed shorted out on a bulldog clip.
-With the print not centered on bed it hit the endstop a few hours into the print.
-I have tried to print from stls not positioned at z-0.
-My cooling fan for extruder unplugged midway through and then the extruder jammed up.
-With the firmware z speed not limited properly, i have lost steps due to rapid z moves.
-Filament strips and stops extruding.
-I have run out of filament.
-On a multi part bed, one part became loose and then slowly caused blobs to build up on other parts. It eventually knocked most of the other parts loose.
-Before I had my heated bed fully figured out I had a LOT of parts curl and then come loose from the bed midway through a print.
-I didn’t check the scale of one stl I downloaded from thingiverse and it ended up being about 4mmx4mm.
Got any more to add? post them below in the comments! I’m sure I’ll keep discovering more.
