Hi, I've had mixed results with the OMC 17HS08-1004S (13Ncm) motors. Some prints have gone fine and suddenly I can not get anything done as it start to skip heavily. I have most problems with HTPLA-CF on 0,4 mm nozzle. With the 13Ncm it starts skipping. But the I can have 2-5mm of perfect print other times. I do not think it is clogging as I can push filament manually. But the motors can get burning warm. The drivers are not warm at all. I tried both the SilentStepSticks and the stock bigbox drivers and the results are the same. Could I do something wrong with the PTFE tubes and they start pinching? Could less microstepping give more torque?
