There is not the grinding as I have had when the print loosens and then the accumulation of PLA around the nozzle blocks it completely. It seems to be stuck retracting and advancing
I am using the "standard" settings of 50mm/s and 0.1mm layer
I will try heating the nozzle to 240C
Thanks

Did the feeder grind into the filament? This would prevent it from moving the material to the extruder. I have no idea what your model looks like, but I am guessing there is a lot of retraction involved. Have you tried printing slower? I print PLA only on a dedicated UM2, anything above 50mm/s and 0.1mm layer thickness is critical. If tolerances are not critical I raise the temperature to 240C which will make the PLA flow much easier. ABS is a different story
