1LC - extruder randomly stopping/reversing - ≤3.5.0-rc1

[dc42]

@Exerqtor thanks, so it does look as though it's the 1LC firmware that has introduced this issue. Please can you try upgrading the 1LC firmware to 3.5.0-rc.1 and see whether that fails or not.

[Exerqtor]

@dc42 It sure does, I can test it out in a little while 👌

3.5.0-rc3+ on the Mini & 3.5.0-rc1 on the 1LC:

I have also identified WHEN (within a rather small margin) in the job file it stops extruding if that's worth anything?

It completes the extrusion of line 3451, but does not extrude again when it's supposed to in line 3460, here is a snippet of the code ("first" line is 3448, "last" line is 3468):

@Exerqtor thanks! I'll look at what changed in the tool board firmware between beta4 and rc1.

PS - the extrusion amount is very small, 0.00282mm. Is that the first point in the file where it is so small?

Np, lets hope it's rather easy to identify and patch out 😅

Uum, i don't think it's the first? If you have a look at the job file I included earlier you can see that it's several of the same-ish size, the same point og the previous layer for instance, here is a snippet of the exact same point from the previous layer (where it completed/didn't stop extruding):

@Exerqtor Is that sliced with Bambuslicer, or Orcaslicer? The M205 jerk changes mid-job are odd. Changes in jerk may be upsetting PA or something. I'd definitely try turning that off.

(Sorry, still haven't got my machine running yet!)

@droftarts Yes it's sliced in Orcaslicer, i've got "Emit limits to G-code" un-ticked in the slicer, but it still hammers in M204 & M205 commands. We touched on it in a separate thread earlier, and i opened a issue on their github regarding it, but it haven't gotten any traction.

Anywho i can do a quick "replace "M205" with ";M205" in my text editor just to see how that fairs right away. And run the job another time.

(Sorry, still haven't got my machine running yet!)

Np, must say i'm curious to how it will react though!

I just tried that, and that just makes it stop extruding at the second part of my purge line. So the M205's ain't the root issue.

Here is a set of reports when it's not extruding with M205 removed:

I just noticed that in several of the tool board M122 reports after extrusion stops, ebfmax (maximum extrusion brought forwards) shows as infinity. That gives me something to look at.

Goodie!

[dc42]

@Exerqtor please try this TOOL1LC firmware. It should be compatible with the 3.5.0-rc.3+ firmware you have already. I am interested in (1) any debug messages that appear in the DWC console (or alternatively on USB if you don't have DWC connected), and (2) whether extrusion still stops working properly.

Duet3Firmware_TOOL1LC.bin

[Exerqtor]

@dc42 Ok I'll give it a go later today.
I've got log level 3 running so i can post that whole "transcript" from when i run the test.

Want me to run M122 reports as well?

[dc42]

@Exerqtor I'd like M122 reports if it still stops extruding, or at the end if it no longer stops extruding,

If it no longer stops extruding, there may be small extrusion defects where it would previously have done so. In this build I detect when the infinity occurs, produce debug info to help me determine why, and attempt to recover from it (which is where the defects may occur).

[Exerqtor]

@dc42 I'm running the test print now, and it's passed the point where it used to fail earlier (it's throwing debug info, so it looks like you're on to something).

I'm going to let it complete and report back with the things you wanted.

As of writing this reply this is the following debug that's appeared in DWC:

[dc42]

@Exerqtor thanks, the fact that it recovers now tells me that the infinity was responsible for the failing extrusion, and the debug tells me which of two places the infinity is generated in. You can stop the print if you wish.

[dc42]

@Exerqtor if I produce another tool board firmware in the next 30 mins or so, will you be able to test it?

[Exerqtor]

Well that fun didn't last long, all of a sudden i got a error in DWC that boar 121 had reconnected. Extrusion stopped at that point, and the tool heater reads offline & 2000.0C.

I grabbed M122 reports once i saw what had happened, then paused and canceled the print.
Here is the reports:

And i'll upload the entire debug log from the point where i started the print from DWC until i canceled it "here". It's INSANELY much getting printed all of a sudden for some reason, so i'll switch to log level 1 instead. It's not added this much to the log before!

[dc42]

@Exerqtor no need to upload the debug log, I have everything I need from the previous report. I'll provide another binary for you to run shortly. I'll also take a look at that M122 report.

[Exerqtor]

@dc42 Oh sorry I didn't see your replies since I was sifting through the debug log lol.

But I won't be able to test anything more today since i'm off to a meeting now, and will be away for the rest of the evening.

So do it whenever you have time and i'll test it tomorrow!

[dc42]

@Exerqtor I reproduced the issue on the bench and fixed it. Please try this tool board firmware.
