      This probably has nothing to do with the firmware and more to do with acceleration and jerk settings of the extruder motor. I'm using a Bondtech LTX Lite which is highly geared at 562 steps/mm at 16x. The LGX lite also uses that silly little nema 14 motor. I'm running it a little hotter at 900mA.

      My guess is a lot of these hiccups are happening during retractions, but I'm not sure. Any ideas on how to fix this issue, or advise whether this is a problem or not? While we're here, Can someone take a look at my max jerk values for X and Y and see If thats a good value for input shaping and PA?

      Here is the M122 B121 output

      Here is the relevant section of config.g

          @jay_s_uk You talking about the hiccups or the jerk values?
