Reume after m601 pause not performing as expected

tsunaminaut

So I have a duet 3 hc6 hooked up too an ender 5 with 3 extruders into 1 hotend rig. I'm using Duet web control on a raspberry pi 4 hooked up via serial cable to the duet 3 board. I'm using perusa slicer as I like how it creates purge towers but have run into the following issue. I want to pause the print to change out the color on an extruder then resume printing. I use persua slicer to insert m601 at layer 2 it does pause althought seems to ignore my pause.g script, but then when I resume it just kinda extrudes a bit of fillament and puts the nozzle back on the print and then pauses again.After 3 days trying to research this I cant for the life of me figure out how to get it to resume printing. I will attach my pause.g and resume.g below in the hopes someone cant point out what I'm doing wrong or maybe suggest a better way to go about this with duet hardware. (I used to use cura slicer with the pause at height on marlin firmware mks gen L board without any issues).
Thanks for your attention!

You want M226 for pause.

M601 is not defined for Duet/RepRap firmware. Nor in Marlin, etc. It is a Prusa only thing.

That was it! I just needed to insert M226! thanks Danal!!!! 3 days I was dreading having to ask someone lol!

dc42

The other command you can use for this purpose is M600. See https://duet3d.dozuki.com/Wiki/Gcode#Section_M600_Filament_change_pause.

tsunaminaut

So I was wrong that m226 didnt resolve the behavior. Basically it seemed to use the pause and resume scripts but then it squirts some plastic on the spot the pause happens circles around and goes back to pause. another oddity it seemed to retract T1 when I was using T0 although none of the gcode appears to have a tool change in it.

https://www.youtube.com/watch?v=3XeIBw7q12c

Danal

I don't use pause a lot, so I could be wrong... but... this looks to me like two different pause commands:

One is "at byte" and the other is "at Xnnn Ynnn Znnn". Any chance the slicer has two different pause things enabled?

What happens if you hit resume print again?

tsunaminaut

@Danal I checked the slicer and there is no custom gcode in it aside from my tool change gcode which shouldn't be coming into play as I'm not changing tools in this test. When I click on resume, it does what that video shows every time over and over and over, like it starts running the code right before the pause m226 so just gets stuck in a loop, I checked the slicer and the only thing I'm seeing is the right click on layer 3 where I inserted M226. (had the same experience with m600 but I don't have any custom filament change g code file saved so am assuming m600 defaults to running my pause.g and resume.g). I checked the gcode file and it doesn't appear to have anything other then M226 in it either.

dc42

It may be a firmware issue. Are you running your Duet 3 with or without a Raspberry Pi connected?

tsunaminaut

@dc42 Running it with Duet web control through a raspberry pi 4 on the SBC 26 pin header.
Board: Duet 3 MB6HC (MB6HC)

Thanks, I suspect it is to do with the way that DSF is handling M226 and M600.

tsunaminaut

@dc42 Is there a way of generating a log to see what commands are being sent by the pi? I'm pretty sure manually pressing the pause and resume buttons inside the web interface work as they should, it feels like upon resume its starting up again right before the pause in the code.

Danal

ssh to the pi, then:

sudo journalctl -u duetcontrolserver will dump the entire log; if to terminal with a 'more' like interface; if pipe or redirect, entire log.

sudo journalctl -fu duetcontrolserver with 'f' will follow (like tail -f) the log. You can leave this running while you try various commands, if you just want to see the log.

chrishamm

Please upgrade your DSF version and check if the problem perists. The print management has changed significantly since v1.1.0.5.

tsunaminaut

@chrishamm updated as follows
Board: Duet 3 MB6HC (MB6HC)
DSF Version: 1.2.3.0
Firmware: RepRapFirmware for Duet 3 MB6HC v0.6 or 1.0 3.0beta12 (2019-11-02b1)

Now M226 does the pause.g script when I hit resume it goes back to the print and throws error below

chrishamm

@tsunaminaut I'm sorry you're still having an issue with that version. I believe this is fixed in DSF 1.2.3.1 which is available on the unstable package feed. To activate it, replace stable with unstable in /etc/apt/sources.list.d/duet3d.list and run a regular system update (sudo apt-get update && sudo apt-get upgrade).

tsunaminaut

@chrishamm Im now on

DSF Version: 1.2.3.1
Firmware: RepRapFirmware for Duet 3 MB6HC v0.6 or 1.0 3.0 (2020-01-03b3)
The issue continues, it appears to be fixed on 1 single extruder print but once I put a pause in a print that has multiple extruders it goes back to doing the same thing as in the video from the above post.

chrishamm

I've prepared another in DSF 1.2.4 which I will release shortly. It will allow you to pause prints wherever you want.

Thanks for reporting this!

tsunaminaut

@chrishamm @chrishamm Appreciate you looking into this thanks! Ill report back if 1.2.4 fixes this!

tsunaminaut

I installed 1.2.4 and now m226 just freezes the printer and it wont resume, also oddly now when I attempt to print files it prints the purge tower base and then just drops the bed untill it bottoms out and starts skipping my z motor. On another test print it was printing a skirt and halfway around it it just started dropping my z as well. I'm having trouble figuring out how to go back to a stable build. would you be able to share a link to the documentation with instructions for that, it would be appreciated as my printer is now unusable.

tsunaminaut

@tsunaminaut Starting to think I have a defective board. I will get a file to print then half an hour later the next time I try to print the same file it just freezes for no obvious reason 1 minute in theres no error codeit stays hot, is there some limit on the size of files a duet 3 hc 6 can handle?. Also I cant find any documentation on how to get back to a stable build do I need to wipe everything out and start over again?

chrishamm

@tsunaminaut Plesse share your sys directory and the file you have been trying to print. I have been unable to reproduce pause problems with 1.2.4 but I would really like to figure out why you still seem to have issues.

For now, you may have more success using the Duet 3 in standalone mode, i.e. with a microSD card installed and without a Raspberry Pi.

smarshall

Was this ever resolved? I'm experiencing the same issue.

Phaedrux

@smarshall Can you share some more info about what you're experiencing? hardware and firmware used? Perhaps starting a new thread with all your details would be best. Link back to this thread if you think it's related.
