Extruder motor hot
Hey fellow makers/printers
I just built my MK3S last week, no major issue so far, 3D benchy print is smooth, no ghosting, ...
I recently noticed that the extruder motor get's really hot during the print, at least hotter that the bed, judging the difference only with the back of my fingers. Is that normal ?
Thanks for the help

All right found an opened issue in the github repository. Hope this get solved, some have reported PLA starting to melt after 4h of print.
RE: Extruder motor hot
I'm experiencing the same thing on my just-completed build. I went looking at the issue you mentioned ( https://github.com/prusa3d/Prusa-Firmware/issues/1757 ) and see that one hypothesis is that it's a bad motor. I'll try contacting support this weekend and see what they say.
RE: Extruder motor hot
mine was getting hot as hell too. I hear downgradeing the firmware helps..
I just added my fan i've had on my extruder back on.
I have a Prusa,therefore I research.
