MK4S Always Fails at Same Point in Print, "Stuck Filament"
I am happy with my new MK4S, but I have hit a problem that has me stumped.
Running a 3.5-hr print, the job stopped about 3 hrs or 81% in, reporting "Filament appears to be stuck." I went through all the rigamarole of unloading and reloading the filament, then resuming the job. The job resumed, but I could tell something wasn't right; the extruder feed was not smooth and uniform, and job soon stopped again, reporting "Filament appears to be stuck." I repeated this routine several times, each time the result was the same. Print quality was notably poorer than usual. At this point I decided the nozzle must be well and truly clogged, so I aborted the print and did a cold pull.
I then restarted the same print from zero. The job proceeded to the same point as before, then repeated the same problem as before. The gcode file is attached.
I don't think this is a filament problem. The extruder was noisier than usual (creaking) throughout the job up to the point of failure, but print quality was excellent.
Could this be a slicer problem? Has anyone experienced something similar? Any help appreciated.
