same result

Not really surprised at that.

Have you tried pressing the DWC Resume button a second time?

Frederick

Touchthebitum · 24 Jan 2021, 15:13

@fcwilt
yes , three, four times

@Touchthebitum said in Pause/Resume print:

yes , three, four times

And each time it returns to the paused state?

Frederick

Touchthebitum · 24 Jan 2021, 15:14

@fcwilt
yes

fcwilt · 24 Jan 2021, 15:17

Can you open the gcode file generated by the slicer and find the place where it issues the M226/M600?

I would like to see, say, 10 lines of the gcode before and after that place.

@Touchthebitum

Thanks.

I don't see anything odd there - all looks fine.

Hmm... My slicer allows me to add my own gcode at different points in the printing

the beginning
the end
layer change
tool change
filament retraction

Does yours have different places? If so is there anything in them?

Frederick

Touchthebitum · 24 Jan 2021, 15:28

@fcwilt
it seems not
I can only edit the gcode on dwc

So that code at the point of a layer change is being inserted by something the the DWC?

I didn't know that was possible.

Frederick

Touchthebitum · 24 Jan 2021, 15:32

@fcwilt
no, I can do it manually on the DWC

fcwilt · 24 Jan 2021, 15:56

I did my testing with a Duet 3 Mini 5 - no SBC attached.

I created a ultra simple test print file - you could do it in notepad if that is all you have.

G1 X100
G1 X-100
M226
G1 X100
G1 X-100

the pause file:

M291 P"PAUSE" R"PAUSE" T1

the resume file

M291 P"RESUME" R"RESUME" T1

It all worked fine.

I suggest you do the same and see if you have a different result

@fcwilt
The solution was M226 instead of M600.
I had to edit and place M226 at the right layer.
I kepts my pause and resume files and it worked.
Thanks for your help

Glad to hear you got it working.

I will need to test M600 as it is documented as being the same as M226 with the exception that if a file filament_change.g is present that is run instead of instead of pause.g.

So in theory if filament_change.g is NOT present it should work just like M226.

ok

https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M25_Pause_SD_print

M25 wasn't going to work.

Do not use this code to pause the print in the currently printing G-code file, use M226 instead. M226 is intended for use in the GCode file being printed, for example to pause after a particular layer has completed. So it waits until all the moves in the queue have been completed. M25 is intended for use from a different source of GCodes than the current print from SD card (like the web interface console, PanelDue or Macro).

Did you have a filament_change.g present?

Can you post the results of M122?

@Phaedrux said in Pause/Resume print:

M25 wasn't going to work.

I did read the docs on that. I was trying to determine why a pause issued from DWC was working for the OP but not a pause from the slicer.

Based on what I read it seemed that M226 MIGHT be equivalent to M400 M25 - it was meant as a test only.

Now using the test files I posted for pause.g and resume.g I was able to use M226, M600 and M400 M25 in the dummy print file and the results were all the same for each - or at least appeared to be based on my interactions with the DWC.

When the M226 (or M600 or M400 M25) was executed the "printing" paused and the pause.g file was executed.

When I clicked the RESUME button in DWC the resume.g file was executed and the "print" completed.

I also verified that IF filament-change.g was present then M600 did invoke that.

I understand that the test files for pause.g and resume.g may somehow bypass important functions thus rending the tests invalid - only @dc42 could tell us that.

When I have more time I intend to code actual working pause.g, resume.g and filament-change.g files and test with a print file that actually prints something.

Thanks.

I was able to print that piece with this code.

The purpose was to change filament 2 times and modify secondly filament printing settings since they are very different. (PLA and Filaflex). The only missing element is the wait for temperature.
When I press "resume", the carriage doesn't wait for the right temp and goes on printing....

Used gcode :

M104 (deprecated see G10 and M116) sets the temps and continues.

M109 (also deprecated see above) sets the temps and waits.
