      Procedure:
      Printing starts properly.
      After about one hour, the extruder0 does not move anymore.
      Extruder1 still works.
      The driving movements are continued.
      Only a restart can fix the error.

      Logging:
      Here is M122 during printing:
      0_1564186966430_ExtruderStandStill.txt

      Alternatives:
      I have replaced the E3D Super Whopper stepper motor with the E3D High Torque Axis stepper motor with the same result. The wiring is correct. I used firmware 2.03+1 (2019-06-18b1).

      It's a similar behavior (but probably not the same):

        What type of printer do you have?
        There are some threads on this forum where users experienced the same problem and was due to static charge buildup caused by plastic spool holder and unearthed extruder.

          It is a custom build. I printed with this extruder0 about 20 kg of filament without this extruder problem (but other problems). Since I installed version 2.03+1 the new extruder error occured.

          Note: 1. Once the error occured after 10 hours.
          2. There was no warning shown in the duet web contol.

            Update:
            I have replaced the wiring to the stepper motor.
            I have replaced the stepper motor.
            I plugged the extruder0 in the extruder4 socket.
            I have updated to the current firmware version.

            The same result. The extruder stands still. EXACTLY on the same position.

            How can I fix it? Perhaps, is in the new firmware (2.03 and later) a timer, who reset anything?

            I printed a test benchy. The error occurs in line 17 in Cura or line 16 in the gcode file after/during the switch to the infill.

              Can you save a .3MF file from cura and post that instead? That will show us all of the cura and printer settings and stl model as well as be able to produce the same gcode.

                Here is the .3mf file:
                Benchy.3mf.zip.cps (Please delete file-extendsion *.cps to extract the zip file
                But you can not generate the same gcode with this *.3mf file. I have written a few postscripts, that modify the original gcode. The generated gcode is correct. I use it since about 6 month for small prints, but I can't print big 3D objects since nearly 6 month (e.g. I2C-Error).

                Here is my alternative to reproduce this print.
                You can use my config.g and the uploaded gcode file.
                0_1564344863120_config(8).g

                Note: All axis stepper motors and three (inclusive extruder0) of four extruder are earthed.

                  Now, I can reproduce it. It is definitiv a firmware error.

                  Here are two versions (358KB):
                  The first gcode file stops extruding after line 635.
                  ErrorInLayer16_Line554_E0.00002.gcode

                  The second gcode file is a copy of the first gcode file.
                  There is only one little change in line 554.
                  I replaced:
                  "G1 F3660 X14.99300 Y-3.21400 Z5.10000 E0.00002 ;Extrudefactor fest + variabel: 1.2312000000000003 ;GeteiltMoveFinish"
                  to:
                  "G1 F3660 X14.99300 Y-3.21400 Z5.10000 E0.00005 ;Extrudefactor fest + variabel: 1.2312000000000003 ;GeteiltMoveFinish"
                  And this gcode file works perfect.
                  ErrorInLayer16_Line554_E0.00005.gcode

                  Note:
                  I reproduced it about 20 times.
                  This was my config.g for this test (In this gcode-version was mixing extruder deactivated):
                  0_1566679632603_config(10).g

                  I hope you can reproduce it and find the error.
                  Thanks
