I just had to strip down my 3d printing toolhead, take it entirely apart and clean out a crap load plastic that had leaked out of the hotend and mucked up the inside of the toolhead. It had stopped feeding filament, and I figured that was the cause. Field stripping one of these suckers is NOT a trivial task, however, and all those tiny wires scare me. Breaking those solder points won’t take much fooling around.
I’d really like a backup on hand asap.
Anyone know the specs on the filament tubes used inside the hot end? and the size of the extruder? I’d like to swap that for a stainless steel one.
