I've been having problems with my PG35l motor. I have to set my extruder acceleration down to 500 mm/s^2 in the firmware in order to get retraction to work, but then my print quality suffers. I have great quality at 1200 mm/s^2 but no retraction. My actual retraction speed is set at 20-30 mm/s. My ability to retract seems to depend on how high I set my extruder acceleration in the firmware but is also affecting quality. Have you ever had similar issues? Thanks for the help
