I’ve been frustrated while using my A350 when the print head goes home after calibration. It causes a few feet of filament to fall off of the spool and risks getting it tangled in the works or on the spool itself when I rewind it.
I’m sure that printing and using one of the numerous self-rewinding spool holders might help with the issue, but I had another idea:
What if I were to design and print a spool holder that mounts to the threaded holes on the back half of the horizontally mounted Linear Module? Then the spool, filament and head would all travel vertically together while printing. As long as the assembly didn’t interfere with the printhead travel or its data cable, the only important question would be “Can the two vertical Linear Modules together handle the extra weight of a spool of filament while accurately moving up and down?”
