Extruder skipping gears on PLA/ABS after trying to print ABS
Hey all,
I'm using the Prusa i3 MK3S with the MMU2S for about a year now, printing all kinds of stuff with different fillaments with more or less no major issues. However, after trying to print some ABS-parts last week the extruder is grinding/skipping gears when printing any kind of fillament (see video) and extrudes wiered looking, brittle fillament. (I'm using the "Load fillament to nozzle" function)
I already tookapart the whole extruder unit, changed the nozzle, cleaned the heatspreader PFTE-pipe, changed the tension of the extruder gearing, nothing worked so far and since I am able to feed in fillament by hand without an issue I have now idea whats wrong and how to fix it, so I hope you guys and gals can help me out.
Cheers
Lucas
