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

Exerqtor

@dc42 said in 1LC stepper intermittently running backwards - 3.5.0-r1+:

@Exerqtor please try the firmware binary at https://www.dropbox.com/scl/fo/uf8gsgetc2mfbh34hm3up/h?rlkey=bx1aavry6xplebwxhv5rx7xee&dl=0 and test it both for the WiFi resetting issue and the extruder reversal issue.

Sweet, but continue to run the "regular" 1LC 3.5.0-rc1+ firmware?

Exerqtor

@dc42 Ok let's see, I've installed those last binaries and the "normal" 3.5.0rc1+ release on the 1LC.

After that I tried one of the jobs that failed earlier, and it completed without reversing the extruder (or crashing).

I'll try some of the other jobs that has failed too now and see of they also complete.

Should i still leave the "stuff" we put in daemon.g be there for a while btw?

(Copying this response to the other thread too, since it's refering to the same binaries)

Well that didn't last long, the next print started reversing after the second layer completed, it's still going as i type this reply.

So here is a few reports from when it's currently reversing:

Aha, ok just moved over to it. I'll try the same job file again before hitting the bunk and report back✌️

Just tried the same print with 3.5.0-c.1++ on the 1LC and it's the exact same behaviour:

@Exerqtor is the reversal random, or at the same point each time in a given print?

Exerqtor

@dc42 Seemingly random, definetly not on the same point/layer each time.

The first time it happened (where i thought it was a clog or something) it happened between layer 59-61 (based on messsuring the height of the failed print), so after making sure there was no clog etc. and restarting the print it began reversing at layer 4-5. And on the third try it started reversing on layer 2.

Exerqtor

@dc42 said in 1LC stepper intermittently running backwards - 3.5.0-r1+:

@Exerqtor is the reversal random, or at the same point each time in a given print?

I just saw this thread and your reply to it. And it got me to remember that i did some IS tuning and changes between it working and these issues came back. May these be connected to each other?

The only changes i did was to alter the frequency and try a couple different shapers to see what changes it did to the readings.

Exerqtor

@dc42 So I just grabbed the 3.5.0rc2 binaries and tried them on the machine, and it's still reversing the the print.

This time I kept a finger on the filament where it enters the reversed bowden while looking at the Z-height and it stopped extruding somewhere along Z 0.65.

Here is a couple fresh reports grabbed while it's acting up during a print:

And the sliced file for good measure.

Exerqtor

I just adjusted my belt tention and retuned input shaping after moving to 3.5.0-rc2, to see if applying new shaper settings would remedy anything.

Started a print, and now it stops extruding earlier than ever, now it only does a tiny bit of my purge line before it stops.

So i thought fuck it and removed the extrusion reset commands from my layer change g-code, sliced the model again and did another try. The exact same behaviour.

Here is another set of M122 reports from while the problem is happening:

And here is the relevant config files & sliced job.
(All these files are grabbed from the printer, so it's 100% the config I'm currently running)

droftarts

@Exerqtor have we already ascertained if the problem goes away when input shaping and/or pressure advance are disabled? What size nozzle are you using?

Ian

@droftarts said in 1LC - stepper randomly reversing - ≤3.5.0-r1+:

@Exerqtor have we already ascertained if the problem goes away when input shaping and/or pressure advance are disabled? What size nozzle are you using?

Ian

No I haven't tried that out yet, been waiting on feedback as to where/what to start with to be honest.

I can try disabling Input Shaping first and see if that yield different results on the same job that I supplied in my last post.

I can confirm that it still happens with IS disabled:

@dc42
I just removed all the "extra stuff "that was put in daemon.g to see if that mad a difference but it still starts reversing. Same if i "disable" daemon.g or run it completely empty.

Now it's on the first line of my 3-line purge/prime code each time "no matter" what i do.

Is it any apparent issue from the M122 reports i've been posting, or is that just a complete waste of time to post those?

Feel like i'm pulling straws out of my ass at this point, but could formating the sd-card and reinstalling all the firmware be worth a try?

I mean, i've been installing so many different builds the last 3-4months maybe something got messed up?

Or is that just nonsense?

@Exerqtor If it makes you feel better I figured out the problem I have been having for the last week is the extruder occasionally stopping. Using a Duet 3 mini 5+ with a RRF-36 toolboard. 3.5.0-R1 on the board and 3.5.0.r1+101 on the toolboard.

I thought it was cooling related since it is a new Dragonfly BMO hotend and EVA34 setup thanks to a fan failure earlier. But nothing is wrong, the heatbreak is clear, the nozzle is not clogged Went through the wiring too to make sure no momentaries were happening.

Not seeing an error and no desire to try it again and waste more expensive carbon fiber PC filament. Plus I am going to be tied up for the next couple weeks, So I'll park that printer and revisit it early next year.

I did kill daemon.g to see if it was related since that and the new hotend assembly were the changes recently done and it did not help. Not seeing any crashes but I am running a different setup than you. Win 10 with Cura slicing the files and firefox running DWC. And the 2 reprints also failed. They sure mess up a print when they happen.

@KenW
Sucks to hear you also have problems, but it really does make me feel better to hear that it's not another "one off" issue, and it's something happening to others as well 😮‍💨

I've got alot of projects I hoped to get done by/in the comming holidays, but it's looking increasingly less and less likely 💩

It's luckily some bog standard ABS i've had to throw in the fuckit-bucket, but it's still annoying af.

@Exerqtor That is the only printer running the beta firmware. It has to run it to use the RRF-36 toolboard. I had noticed your post but was ignoring them since I thought it was filament getting stuck in the heatbreak or possibly carbon fiber jamming the nozzle. I can take down and reassemble the EVA in minutes now with all the practice I have been getting.

Since mine is not acting up exactly like yours unless your extruder just stops for a bit then restarts with no error maybe it's another issue.
After I get back home in a few weeks I'll play around more with it,. Gave up today on the print I was trying to take with me.

Exerqtor

@KenW I also thought i had gotten a clog or something when it started happening again so i get your logic lol. It will be interesting seeing how it plays out when you get some time to look at it again.

I just reverted to 3.5.0b4 on the mobo & toolboard to see what happens at least, too be continued.

EDIT:
After reverting too 3.5.0b4 I was finally able to complete the print without issues.

I'm gonna try doing some more prints after work tomorrow to see if the "solution" holds, but it sure looks like the problem lies in 3.5.0-rc1/2.

Exerqtor

@dc42 I've ran over ballpark 24hr of prints on 2.5.0b4 now without any issues.

Weird that noone else reports about this.

A Former User

@Exerqtor Not home to look at anything but it might depend on the setup. I had another printer earlier that I also had a duet 3 mini 5+ with 3.5.0 r.1 and a RRF-36 mounted with 3.5.0 r1 firmware. That was an ender 3 pro, a simple bed slinger. I did multiple test prints on it before it was wrapped up as a gift and hauled up here. In 5 days it gets to live again and hopefully will still be problem free.

The printer giving me problems is a CoreXY with 3 Z steppers and a klicky so a bit more complex and different motion system. Also a Duet 3 mini 5_ with the other RRF-36 and the same firmware as the ender.
