TIPS! Extruder cable routing stiffener
On my previous MK4S, there was a nylon stiffener in the sheathed cables which prevented the sheath from sagging.
On the Core One (upgraded whith my MK4S ) , this sheath is a disaster and dangles miserably. It's not too annoying, but it's not attractive and looks very amateurish...
So I salvaged the stiffener from the MK4S and positioned it in the extruder cable sheath; it's much neater... plus, the 90° curved end fits perfectly into the hole in the Prusa Swing Arm, as if it were designed for it.
I've since done many prints with the MMU3 or the original spool without any problems. If this helps, I'd be very happy
