      Spacer.gcode
      Spacer.stl

      Attached file is a small-spacer-part. (8 x 20mm cylinder)

      I have several printers.
      One of them is Duet2 Ethernet + Duex5 + RRF3.2.2
      The other is Duet3 6HC + 1LC + RRF3.2.2

      Duet2 board can print it perfect.
      Duet3 + 1LC does not print properly.
      It seems that the 1LC Extruder ignores the movement of the short filament as '0' through several experiments.

      It is not a motor torque problem. When I disassemble the extruder and observe the extruder motor, it hardly rotates unlike duet2.

      Even printers with Duet3 + 1LC seem to print normally when printing large obects. But, looking it closely, thin-walled-infills were not printed properly.

      Please comment on what I need.

      If you have 1LC-Extruder-printer, please print the attached STL. (It's very small, - 20x8mm cylinder) And I hope you would share the result.

      Thanks.

        You could try the latest beta build posted by dc42:

        If that does not help generally a M122 report directly after the problem occurs might help the devs to analyse the problem.

            I leave the results for those who suffer from the same symptoms as me.
            This issue was resolved in RRF 3.3
