Filament gets stuck repeatedly during printing
Hello all,
I recently upgraded my MK4 to MK4S. It's located in an official Prusa Enclosure. I'm currently using official PLA or PETG from Prusa.
While I was happy with the MK4 reliability and print quality, I had recurring issues with the MK4S immediately after the upgrade with the filament getting stucked/jammed ("bloqué" in the french messages displayed on the LCD) randomly during the prints. The prints are paused, then I have to intervene to proceed with an unload-reload of the filament before being able to resume the print (I'm grateful for that feature that saves my prints, but not without some traces or stringings).
Before the upgrade the printer was not equiped with that silicon sock on the hotend. The two screws with the springs that tense the idler seem to be set correctly (i.e. the screws are flush with the plastic part).
I wonder what can cause that issue: is it too hot in the enclosure, with the silicone on? Does it come from that new hotend? Does the idler adjustment too soft or too stiff? Is there some firmware bug?
I already tried to print with the enclosure doors open.
Has anyone encountered this problem, or have any idea on what could cause it?
RE: Filament gets stuck repeatedly during printing
- I am having this problem with my 4s too. But when I reload it stops after about 20 seconds. It rendered my machine useless. It's never completed a print. I think my sensor is no good cause it only registers a filament in there if I jam it in with pliers and even then it only works about 1 time out of 20. Many broken bits of filament and a very expensive machine that I bought because it's supposed to never fail. And it's never succeeded
