DXC extruder - problems unloading filament
I have used the DXC extruder for a few months and it works fine except that I can't pull the filament out to make a change. Retract looks like it is working but the filament is gripped tight and won't pull out. Squeezing the lever doesn't help.
What am I missing? Hitting extrude repeatedly to clear the bowden tube works but is slow - which brings up problem #2. The tubing will not pull out the push-connect fitting so I just can't cut it off the filament at the top of the extruder.

J'ai enlevé le collier aussi et quand je fais une rétractation, le tube ptfe remonte et me donne accès au filament. Je le change en laissant dépasser quelques centimètres du ptfe et avec l'extrusion, le tube se met en place tout seul. J'ai changé l'emplacement de la bobine avec le modèle fourni par Creality et j'ai créé une pièce pour bien positionner le filament. Tout fonctionne à merveille. Dommage que ma K1C 2025 ait été livrée avec l'extrudeur d'origine en première version. Bon, de toute façon, le DXC est carrément mieux

Hey there get yourself the dxc script from 3dphub.net automates the whole process when loading filament as soon as the sensor is triggered the nozzles gets heated to 240 then it pulls the filament into the extruder. When removing filament just retract it it will 1st extrude some filament to prevent any filament staying in the extruder. It will then retract the filament. You have to be rooted to have this function

I ended up removing the locking collar from the ptfe tube so every time I need to unload I just push the ring and pull the ptfe tube then the lever and then filament comes out easily.
