Ultimaker S5 Stuck With filament coiled and I can't make it unload

[eddieparker 3]

I did a print last night and it failed, and it blew out past the bowden tubes and coiled all around the inside of the printer.  Aborting the job is fine, but now the printer is stuck saying "Extruder 2: Material in use" so I can't make it unload it.

 

I've tried rebooting it several times (the material station, the UM5, everything) but it's still jammed.  How can I fix this?

Provided this is interpreted correctly. There are basically two solutions.

The patient one. After about two hours he moves back alone.

The tricky one. Start another print job that pulls material from another slot.

Hrmm, interesting.  I waited a couple hours and it pulled back the filament from the OTHER core, but it left the one that's stuck.  I'll try printing something small and see if it works?

 

I'm really bummed out at all the corner cases that get this expensive machine stuck. :(

OK, the printing something else sorta works.  It basically rewinds *some* of the filament, then gets unhappy it's taking too long, and craps out with an error message.  I have to power cycle the machine, send another print through.  I've done it 3 times now and it just fixed itself.

 

Thanks for the tip, but I really wish I had better manual control over this versus "faking" the machine into doing what I need it to.

The material can actually also be pulled back manually through the station. Open the feeder and off you go. It just does not always work. I do this very reluctantly and would therefore not recommend it.

 

True, finding the detours it takes to force the machine to act in different cases doesn't make it any easier.

 

Wish you continued success
