Re: Problème extrudeuse E1

Re: A20M Feeder Arm Replacement

Another one breaked... have a look to this thing https://www.thingiverse.com/thing:3456879 , maybe be you can use your second extruder to print it.

It will probably break again as it have the same design issues (too thin parts)

Also, I will advice to simply replace both extruders with full metal one

Pour le moteur qui ne fonctionne pas il faudrait intervertir les drivers sur la carte mère pour vérifier qu'il n'y en ai pas un de grillé
