      not sure what I am doing wrong, but M929 S3 P"/sys/log.txt" did not produce any file.

          @bugpwr said in resume redundant extrusion:

          I don't see a similar note on M906,

          It's the last note in the M906 notes.

          I think we need the debug output of the Gcode module, rather than the system log (I don't think this will show much, and is rather impenetrable), which is summoned by M111 https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m111-set-debug-level
          Send M111 to see what is enabled currently (nothing), and enable the Gcode module. eg

          M111
Debugging on for modules:
Debugging off for modules: Platform(0) Network(1) Webserver(2) Gcodes(3) Move(4) Heat(5) Kinematics(6) InputShaping(7) Debug(8) PrintMonitor(9) Storage(10) PortControl(11) DuetExpansion(12) FilamentSensors(13) WiFi(14) Display(15) SbcInterface(16) CAN(17) Expansion(18)

M111 P3 S1
Debugging on for modules: Gcodes(3 - 0xff)
Debugging off for modules: Platform(0) Network(1) Webserver(2) Move(4) Heat(5) Kinematics(6) InputShaping(7) Debug(8) PrintMonitor(9) Storage(10) PortControl(11) DuetExpansion(12) FilamentSensors(13) WiFi(14) Display(15) SbcInterface(16) CAN(17) Expansion(18)

          Debug output is normally sent to the USB port, so connect a PC with a serial terminal to the Duet, and hopefully you can capture if an errant Gcode is being sent on resume. Possibly turn on the 'Move(4)' module too. Hopefully this will give us a clue what is going on.

            @droftarts for now - this is debug(3) output. Personally, I don't see anything criminal here:

                @bugpwr Thanks, I've asked @dc42 to have a look, see if he can see what's going on, as I'm not sure how to read the 'move' output.

                  @bugpwr I've taken a look at your debug output and I don't see anything abnormal in it. I can see the 10mm reprime move being generated correctly. After that I see some small extruder movements in combination with XYZ movements as commanded by the file.

                  Are you certain that the 10mm retract operation is being performed correctly? It might be helpful to try the pause/resume with the nozzle removed so that you can see whether the correct amount of filament is being retracted. If the retraction is not being fully performed, that would account for the reprime move ending up with the extruder skipping that we can hear. Perhaps you should try reducing the speed of that retraction in pause.g.

                  If that doesn't resolve it, please can you try putting a G1 G4 S2 command at the end of resume.g to add a 2 second delay. Then see whether the uncommanded extrusion follows on immediately from the 10mm reprime move (before the delay), or after the delay.

                      @dc42 hi dc42, first - thanks for stepping in, this is much appreciated.
                      I have performed the experiments. Starting from the end - after adding the G4 delay, it's seen clearly that this extra E move happens after the whole file. (should I try adding M400 before the wait?)
                      The "redundant extrusion" happens very fast, unaffected by the F parameter in "G1 E10 F300" from resume.g, while the priming move is indeed affected by the F setting (with F300 for example, it is fairly slow and completed just fine, but then comes that extra move which is ultra fast and causes extruder skips). By the way, the F300 speed would not cause the skips, it would just extrude the filament. I tried making this even slower and I see the change in the normal priming move.

                      So, the source of the move is elsewhere (my honest guess would be that it has something to do with the "confinement" of relative move coordinates between the macro and the job file and switching between the two, but I have no evidence). Also, judging by the speed of this, it does not seem to come from any "actual" gcode in any of the files.

                      Here's another strange observation that is probably unrelated but may provide some useful evidence: the print head does not decend to the model before the G4 wait I have inserted; instead, it remains 5mm above the model, then the wait, then the failed extrusion, and then the print proceeds with print head descending to the last move. Thanks again, P

                        It might be just coincidence, but I remember having a similar issues all the way back in 3.5.0 and never found a fix for it

                            @droftarts unfortunately so. My only solution was to half the de-retraction amount knowing it would double itself

                              @Notepad okay, reading the word 'double' sent me to do more tests. Indeed - the overextruded amount seems to depend on what's written oin resume.g, but not exactly double - it seems like tripple to me. That is, changing "G1 E10 F300" to E1 (1mm) makes the additional extrusion something like 2mm. If this command is completely removed, there's no extrusion before or after the G4. Hope this could give some insight.

                                @bugpwr I'm looking at your debug trace again and now I can see the extra extrusion. Following the G1 E10 command there are 7830 microsteps of extrusion at a top speed of 3915 microsteps/sec (5mm/sec) with acceleration at the start and deceleration at the end. Then there are another 7830 microsteps of extrusion at a top speed of 15660 microsteps/sec (20mm/sec), again with acceleration at the start and deceleration at the end.

                                I will take a look at the 3.5.4 source code to identify the reason for this. Meanwhile, please can you try upgrading to 3.6.0-beta.3. There have been fairly substantial changes to the movement code in that version since beta 2.

                                  @dc42 this is not 3.5.4, this was actually the latest beta2 (I will try with beta3 later today).

                                    @bugpwr I think I found the problem. It only affects Duet 2 and Duet Maestro. Please try the 3.5.4+1 firmware binary at https://www.dropbox.com/scl/fo/xx7tpppxwbirz4zm9yr0o/AEb98egoCKGGVfCydwsFit8?rlkey=q1eg5g59zt1rbr9wqam80zygx&dl=0.

                                    Edit: the same bug is present in the Duet 3 builds of 3.6.0-beta.3.

                                            @dc42 many thanks, the beta3+1 update works like a charm!!
                                            (completely unrelated: speaking of 2.85mm systems, I don't want to bother you with a minor thing, but it would be awesome if M404 would upate move.extruders[].filamentDiameter. As of now, DWC always shows incorrect volumetric rate for 2.85 machines)
