RRF 3.5.0-b3 sporadically stops extruding

Exerqtor

Ok, so i finally managed to get a diagnosis when it wasn't extruding:

I find this a part a little bit interesting Driver 0: pos 0, 568.8 steps/mm,standstill,? If i run a diagnosis while it's working as intended it's saying ok instead of standstill 🤔

This was on the first layer of the print, where i'm not doing any funny stuff. It's locked too 500mms/3 acceleration through that whole layer.

Don't know if it's worth anything, but this is the job file.

I've ran that job file three times now with PA on, and it stops extruding each time it starts the first layer infill.

I'm printing another one of the same job now, with PA disabled, and it's just finished with the first layer WITHOUT the extruder halting. So it looks like it's something going on with the PA,

@Exerqtor i can also replicate an issue with PA and IS enabled using 3.5b3. Best to disable PA if you can for now as it seems to print ok without it enabled

Glad to hear it's not an isolated issue on my end at least. Yup, keeping PA of for the time being, while looking out for other bugs 😅

EDIT:

I retract my statement about disabling PA and keep trying it out. Since it's another bug that causes the whole printer to reboot at random (seemingly) intervals without any reason. So i'm reverting to 3.5.0-b2 again.

RIP 3.5.0-b3, you won't be missed🙈.

@Exerqtor This may be too late, but if you get a reboot can you run M122 after it restarts and post the output. The info in there will help a lot with trying to solve the issue. It is probably worth checking the M122 output now (from whatever version you are now running) as the data from the previous crash may still be present.

Exerqtor

@gloomyandy
Yeah it's way to late at this point, after the third reboot i reverted to b2. Don't look like it's a prevalent issue either since it's not being reported by anyone else.

gloomyandy

@Exerqtor It may not be too late, the reset data is stored in flash that may not be erased when you reinstall. Worth checking to see what M122 reports.

gloomyandy

@gloomyandy Also even though others may not be reporting the problem, it may give clues towards other issues, so definitely worth reporting if you possibly can.

Exerqtor

@gloomyandy I can pull a M122 from both the mobo and toolboard as soon as this print finishes.
If it's anything worth looking at or not i have no idea 🤷‍♂️

@Exerqtor This (and the stack trace that follows it) is the part of interest....

@Exerqtor Unfortunately it looks like the reset data has been wiped by the older firmware. Oh well, thanks for taking the time to check. If you do decide to try 3.5.0-beta.3 again and you get a reset please grab the m122 output and post it.

Exerqtor

This issue has been solved as of RRF3.5b3+!

i was about to start a new topic. i recently upgrade to 3.5.0-Beta3 and now i have extruder issues. I use 2 toolboards 1LC on an IDEX machine. It appears that my extruder motor stops extruding during printing. it seems to happen right after a toolchange to select the new extruder. The toolchange does some fast extrude retraction.

Once this behavior happens i have to reboot the printer to restore back to normal behavior.

I am reverting back to firmware 3.4.2 for now. hopefully my issue is part of this fix in the Beta 4 next release.
