Filament stuck
Hi my name is Guido. I 'm new on 3D Printing and I bought a Mk3 that I assemble on past satuday. The thing is that since past saturday the filament get stucked twice between the hotend and the hobbed pulley. The fist time I unassembled all the extruder for clean it but I don't want to do it again.
Any suggestions? Any fix for this filament clogging?
I attach a photo of the las clogging
Thanks
Re: Filament stuck
This seems to be a common issue of filament getting stuck when unloading. The best solution so far is to pull the filament when unloading and do not wait. This is another solution: https://www.thingiverse.com/thing:2748862

Check to make sure that your drive gears are lined up properly. It looks like the drive gear attached to the extruder stepper motor is out a tad far. Hard to tell from the photo but worth checking. Also, check to see that the screws are properly tight on it.
Re: Filament stuck
My suspicion is that the gears were very tight and with the heat of the extruder made it deform and stick against the channel and there it accumulated.
I'll see if I can modify that piece to put a fan to see if it solves the problem.
Thank you all for the comments
RE: Filament stuck
This happened to me for the second time today. I disassembled the extruder and cleaned everything, made a Wizard setup and first layer. In the meantime, the electricity went out while he was working for the second time. What could be the cause?
