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

@dc42 said in 1LC - extruder randomly stopping/reversing - ≤3.5.0-r1:

@Exerqtor please test whether the new firmware binaries at https://www.dropbox.com/scl/fo/p0136wx04h8xf6ejwdnn9/h?rlkey=efrfwyb6o5tqid11gustz3uvy&dl=0 fix tihi issue.

Just had time to try it, and it's still the exact same behaviour.

Screenshot of the temperature chart during warmup, working print & failing print (to show that the temps are stable, the drop off at the end is from when i cancelled the print) :

[dc42]

@Exerqtor are you saying that when the issue occurs, the hot end stops heating and cools down?

Last reset 00:17:36 ago, cause: VDD brownout

Looks like the 1LC lost power.

@dc42 said in 1LC - extruder randomly stopping/reversing - ≤3.5.0-r1:

@Exerqtor are you saying that when the issue occurs, the hot end stops heating and cools down?

No nothing happens except it stops feeding filament. The cooling down part in the temp chart is from after I've cancelled the print.

I only included the temp charts to show that the temps are stable (I've updated the "caption" for the chart images on the original posts to reflect on that now).

Last reset 00:17:36 ago, cause: VDD brownout

Looks like the 1LC lost power.

That's from the reset point is from when i rebooted the mainboard after installing 3.5.0-rc3+, I've got relays on the 24v lines controlled with PS_ON.

[Exerqtor]

@dc42 Got any ideas for things i can do to try helping you narrowing down whats causing this?

Needless to say it renders the machine useless.

[Exerqtor]

@dc42 I've looked at the commits you did to 3.5-dev yesterday, are these potential solutions for this bug?

[dc42]

@Exerqtor yes, possibly.

[Exerqtor]

@dc42 said in 1LC - extruder randomly stopping/reversing - ≤3.5.0-r1:

@Exerqtor yes, possibly.

Bad news then i guess, i just installed and tested the 3.5-dev build chrisham built a couple hours ago and tried a test print. And it's the exact same behaviour as before.

All averaging filters OK

(Had to grab them from the debug file because DWC disconnected and i lost the console printout).

[dc42]

@Exerqtor thanks for testing this again. I'm puzzles that ebfmax is showing as zero in the Move section of both M122 reports. After doing some printing, it's normally close to 1.0.

[Exerqtor]

@dc42 No problem, yeah i have no idea what could be the cause 😓

[Exerqtor]

@dc42 i saw you added some more debug features for the expansionboard firmware on friday, do you have a build with that i could try to run? Or do you need to put some more things in it first?

[dc42]

@Exerqtor you are very welcome to try the new Duet 3 Mini TOOL1LC and files at https://www.dropbox.com/scl/fo/p0136wx04h8xf6ejwdnn9/h?rlkey=efrfwyb6o5tqid11gustz3uvy&dl=0. The changes clear up some issues I was having with debug output, caused by variables that were output even when they should not have been used in the current context. I don't think they should change the printing behaviour, but I could be wrong.

[Exerqtor]

@dc42 I'll try it this evening, maybe it will give some more insight into whats causing the stops (one might hope).

[dc42]

@Exerqtor please use the updated (this morning) main board file from there too.

[Exerqtor]

@dc42 said in 1LC - extruder randomly stopping/reversing - ≤3.5.0-r1:

@Exerqtor please use the updated (this morning) main board file from there too.

Just had time to install and test those binaries, and the behaviour is the same (as expected), here are the treports:

Regarding when it stops extruding, i'm 99.9% sure it is when the inner & outer walls/perimeters of layer 3/0.65mm is done and when it goes over to the other part(s) of that layer (still using the same sliced job as supplied earlinger without alterations).

@Exerqtor thanks for testing. I've tracked down a bug in the input shaping code that could result in the main board asking the tool board to apply IS to a move when it was not possible. This could be relevant to your issue. So please try the new main board firmware at https://www.dropbox.com/scl/fo/p0136wx04h8xf6ejwdnn9/h?rlkey=efrfwyb6o5tqid11gustz3uvy&dl=0.

Ok I tested those binaries (I see that it's been updated/changed just two hours ago at the time of posting this reply) and it's still the same unfortunately. Here is some reports.

@Exerqtor do you only see this issue when input shaping is enabled? If so, please try the new main board binary at https://www.dropbox.com/scl/fo/p0136wx04h8xf6ejwdnn9/h?rlkey=efrfwyb6o5tqid11gustz3uvy&dl=0. It fixes a bug that could cause RRF to send expansion boards moves that were impossible to implement in time, which could have been causing the tool board to get confused. It also avoids sending tiny acceleration moves, which I spotted was happening quite often.

[Exerqtor]

@dc42 I haven't tried running a print in a while with IS disabled so i can't say if that and determining factor.
But i did try the print with IS enabled and the binaries you linked to just now (that's 2 hours old according to dropbox).

---

I'm running a new test now with IS disabled, give me a couple minutes and i'll report back on how that turns out.

[Exerqtor]

@dc42 Ok that's something else, with IS disabled it totally shits the bed from the get go. It won't even do the purge line and stops extruding right off the bat (can't feel any feeding movement at all when i touch the filament going into the reverse bowden either.)

@Exerqtor where did you get the tool board firmware from? The date reported by M122 doesn't appear to match the one on Dropbox that I installed on my toolchanger.
