youtube link at youtu be: c0CzmD-DGdg?si=Dh9AtsguJKMDB1lt to see the phenomenon in action. an overextrusion is clearly heard at 00:26

Link to video is https://youtu.be/c0CzmD-DGdg. In case you can't post links, I've upvoted your post, so you should have enough reputation now.

Yes, it certainly looks like it's over extruding. I can't see anything obviously amiss; gcode is using relative extruder moves, and there's not extra extrusion moves in resume.g. Any time you pause a print from SD card, the state of the print is saved to a special file on the SD card, sys/resurrect.g. Can you pause the print, copy that file and post it? Also, does the same thing happen if you pause and resume from DWC rather than Paneldue? What firmware version is the PanelDue running (check the 'Setup' screen)?

hi,
yes - same behavior with DWC and PanelDue. This has been around for a while. Also, if I may share my gut feeling of being around Duet systems - I believe this is very common. Not sure what's different (perhaps it's related to the fact I have a 2.85 system?). It may be that some people don't notice this because this "redundant" extrusion happens very fast - and often the extruder is upable to push the filament through, missing steps.

PanelDue v3.5.5-v3-7.0

I don't think it's common, or the forum would be awash with people reporting it. Not to do with a 2.85mm filament either; I run a tool with 2.85mm filament, and haven't experienced this.

I can't see anything in the resurrect.g file that would be causing the double extrusion. Can you add a line to your "resume.g" to see if it's running twice? eg

; resume.g
G1 R1 X0 Y0 F6000 ; move XY first to saved pos
G1 R1 X0 Y0 Z5 F6000 ; go to 5mm above position of the last print move

G1 R1 X0 Y0 Z0 F6000 ; go back to the last print move
M400 ; wait for moves to complete
M83 ; relative extruder moves
G1 E10 F300
echo "If you see this twice, resume.g is running twice!"

I've had a good look through your config.g, and there are a few things worth changing, though I don't think they'll impact this issue:

Motor settings

M350 X16 Y16:16 Z16:16:16 E16 C16 I1                        ; configure microstepping with interpolation
M92 X80.00 Y100:100 Z1600:1600:1600 E783 C80	; these are the correct theoretical model. measured with orca calibration 
M566 X300 Y300:300 Z10:10:10 E320.00 ;120.00          ; set maximum instantaneous speed changes (mm/min)
M203 X10000.00 Y10000:10000 Z600:600:600 E1200.00         ; set maximum speeds (mm/min)
M201 X6000.00 Y4000:4000 Z100:100:100 E450.00             ; set accelerations (mm/s^2)  
M906 X1200 Y900:900 Z1800:900:900 E900 C80 I15              ; set motor currents (mA) and motor idle factor in %. My extruder is rated for 1A

All of the above Gcodes should only have one parameter for the Y and Z axes. While the extra ones are usually ignored, it has caused issues in the past. eg see the notes for M350 https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m350-set-microstepping-mode

RepRapFirmware does not support individual motor settings where an axis has multiple motors connected to different stepper drivers. The first parameter specified will be used for all motors on the axis. You should use identical motors on any axis that has more than one motor to avoid unexpected behaviour.

Also, you have different values for the motor current for the three Z motors in M906.

Z probe

M558 P9 C"^zprobe.i^H^H^H^Hn" H5 F120 T6000            ; set Z probe type to bltouch and the dive height + speeds
G31 P20 X-31 Y1 Z1.12                        ; set Z probe trigger value, offset and trigger height; lower Z means print higher. NOZZLE: 0.5 HF
M375 ; load height map

Probably just a typo, but there's some stray characters in the M558 line ^H^H^H

Also, you're probably getting a message at start up about 'a significant Z offset`, because you're loading a height map when Z isn't homed. Comment out the M375, and load the heightmap after Z home.

Once you've changed the above, send M98 P"config.g" and check if it reports any errors.

If the issue persists, you may need to set up logging so we can catch what Gcodes are actually being sent.

hi,

First, thank you very much for the review of my gcode. I have removed the extra ":" entries except in case of motor currents, where different Z currents are on purpose: there are 4 motors connected to 3 controllers, I did not have a spare (also, I don't see a similar note on M906, though I guess I have been excessively optimistic). These changes had no effect on the situation unfortunately.

I have performed the "echo" experiment, no double execution of resume.g.
By the way, it would not have caused this result - because the speed of this "extra" extrusion is very different from F300 - it is really really fast.

I have noticed a somewhat strange result of M114, not sure if related:
X:335.750 Y:194.700 Z:44.300 E:0.000 E0:76.4 Count 26860 19470 70578 Machine 335.750 194.700 44.300 Bed comp -0.188

will go on with the logging and report.

bugpwr

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

Sorry my bad, here's the log that should include a couple of the pause eventslog.txt

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:
