Pause/Resume print

[Touchthebitum]

Hello
I'm getting crazy with this feature.
I use Cura 4.8.0 script to do a pause during print to change filament.
When I touch "resume" on my PanelDue, the carriage goes to the last position but then turns back in "pause" mode at the pause location.
I use a Duet3 SBC with 3.2 firmware

Here are my "pause/resume files from a forum user :

; Pause macro file
if state.currentTool != -1
M83 ; relative extruder moves
G1 E-4 F2500 ; retract 4mm
G91 ; relative moves
G1 Z5 F5000 ; raise nozzle 2mm
G90 ; absolute moves
G1 X0 Y85 F10000
M106 S0

; Resume macro file
M106 R1
G1 R1 X0 Y0 Z2 F5000 ; move to 2mm above resume point
G1 R1 X0 Y0 Z0 ; lower nozzle to resume point
if state.currentTool != -1
M83 ; relative extruder moves
G1 E4 F2500 ; undo the retraction

Cura's script :
I can't upload file

PS: when I use touch "pause" and "resume" on the Paneldue, it works perfectly.

Thanks

How are you doing that?

Thanks.

Extensions --> post processing --> modify g-code

Sorry - I meant what commands are you issuing.

Sorry again - what GCODE commands are being generated by the slicer to perform the filament change?

sorry

Thanks.

Can you edit that code?

Since the firmware is trying to handle the pause/resume operations on it's own using the pause/resume files it would seem that the slicer generated code should not include any code that duplicates what those two files do.

So if the firmware pause/resume files do EVERYTHING that is needed then the slicer code should only be M226 or M600 for pause and nothing for resume.

Yes I can edit it.
Ok, thanks, I'll check that

[Touchthebitum]

nothing to do
I only placed M600 on the gcode. The pause is perfect but when I press on "resume" it goes on the print point and turns back on the pause location ...

I don't understand what you mean by "goes on the print point" or "turns back on the pause location".

Can you phrase that another way?

@fcwilt
the carriage turns back on the last printed position BUT doesn't print, then it turns back on the "pause" location

[fcwilt]

@Touchthebitum

Still not clear.

Are you saying the carriage moves to the correct location for resuming BUT the printer returns to the paused state?

Frederick

[Touchthebitum]

@fcwilt
exactly

Great.

And if you pause then resume using the Pause and Resume buttons on the DWC it all works correctly?

Frederick

[Touchthebitum]

@fcwilt
yes

Great - now I fully understand what you are doing and seeing.

What I don't understand is why pausing from the slicer isn't working. I have an idea but I need to try to verify it.

Perhaps we will get lucky and @dc42 will jump in here.

@fcwilt
Pausing is working but resuming not ...

Can you try to remove that from the resume.g?

Tried but nothing changed
