Prusa MK4 with enclosure filament feeding (lemmy.world)

submitted 8 months ago by [email protected] to c/[email protected]

I'm contemplating a Prusa MK4 + official enclosure and I'm looking at the way the enclosure handles filament feeding into the (N)extruder. Normally, filament is loaded directly from the spool into the extruder, but with the official enclosure, I see it's fed through a PTFE tube and coupler. It seems to me this would make changing filaments mid print quite a pain. Would I be ok simply feeding the filament into a PTFE tube, but cutting it way short of the extruder and simply feeding it in from there into the extruder without the tube?

So one thing I’ve discovered is you can’t have ANY resistance on the spool when the printer is homing. If the filament goes taught as the extruder moves down, it thinks the nozzle moved up and thinks it has a homing error.

Thanks, whatever I design I'll keep that in mind
