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

[droftarts]

@Exerqtor I'm going to set up a printer tomorrow with a Mini 5+ and 1LC, to see if we can replicate this issue. Can you post your current config.g and any other relevant files (I can't immediately find them in the thread, sorry if you have already posted them), and tell me a little about your printer? I think you have a Voron Trident or something similar, with a Stealthburner? It would also be good to know what extruder and hot end, nozzle size, filament type and size, etc. I'm a bit limited in hardware, but I'll try and replicate your setup at least functionally. Is the gcode file you linked in the first post of this thread still the one all the tests have been carried out on?

@droftarts
I'll take a complete SD-card dump and upload later today including the job file. I think I forgot to do it earlier dispite saying I was going to do so a while back🤦‍♂️

Specs:

• Voron Trident
• Meanwell 24v & 5v PSU (original, not clones lol)
• Keenovo 230v bed heathwr, through a Omron SSR.
• Stealthburner toolhead with optoTAP
• Stealthburner leds connected to the mainboard (if you want / have the parts to test that)
• Highflow(60w) Revo micro (with a 0.4mm HF nozzle atm)
• LGX-lite and a 0.4mm highflow nozzle
• Hall-element filament runout sensor
• Regarding filament I've tried and comfirmed it bugging out with both 1,75MM Flashforge, Esun and Fiberlogy ABS/ABS-plus & ASA.

[droftarts]

@Exerqtor Okay, thanks. Your machine might be a little tricky for me to replicate with what I have on hand, as I don't have any high flow hot ends or an LGX. Was the problem noticeable when you did an air print, ie with no filament? That way I won't have to reduce speeds, which may be a factor. I do have a pancake stepper

Regarding board setup, it's just the Mini 5+ and 1LC connected? What length is the CAN bus? And you have soldered the termination jumper on the back of the 1LC?

Ian

[Exerqtor]

@droftarts I haven't tried an unloaded print, I can try that later today (all though i'm quite sure it will behave just the same).

Yup, just those two boards and the jumper is soldered. Regarding canbus length it's 1000-1200mm at most, done with twisted FEP wires.

[Exerqtor]

@droftarts
Okey, here is the SD-dump (I just took it), the only things I've left out is the "System Volume Information" folder, the debug logs and any other sliced jobs than the one I've been using for testing. And regarding IP-address and WiFi setup that's all done in runounce.g so you will have to deploy that yourself, as i suspect you're well aware of lol.

Just as a heads up regarding testing the "air print / unloaded" i'm going to alter the jobfile so the bed temp is 30C, gonna try that now and report back.

[droftarts]

@Exerqtor Great, thanks. This will have to wait until tomorrow now. Don't forget to enable cold extrude with M302 P1!

Ian

[Exerqtor]

@droftarts
Np, do it whenever you got time Yeah i skipped changing the hotend temp just incase the powerdraw to the toolboard might be a issue, still haven't had time to run it yet lol.

---

Well that's for sure a definitive answer that loaded filament wasn't the issue, now it's acting up from the first layer again. Won't extrude at all during the print. However if I pause it and manuallly try to extrude through DWC or PD it extrudes without an issue.

Here is the reports from the ongoing test without any extrusion:

The only extrusion it did by itself is the load sequence right before doing the purge lines, not even the purge lines themself yielded any movement.

[dc42]

@Exerqtor I see that there are some hiccups on the tool board. Does it make any difference if you use M220 S50 just before starting the print, to run it at half speed?

[Exerqtor]

@dc42
I can add it to the job code manually and run another test, give me a couple minutes and I'll report back.

Nah, same exact thing only does the nozzle loading sequence then nothing:

For some reason the half speed factor didn't apply, I just set in manually in DWC and ran another set of reports on the same print session (still no extruder movement):

I went through the whole system macro by macro in executed order another time yesterday evening and i can't for the life of it find anything that could cause the behaviour this time either.

How big is the code changes between 3.5.0-b4 and 3.5.0-rc1 in the regard to what might produce this bug? Given that everything plays nice in beta4 it seems rational to assume that the buggy code got added at that point, and is still persisting in the following release candidates.

[droftarts]

@Exerqtor The changes should be listed here: https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x-RC#reprapfirmware-350-rc1-changes-since-350-beta4
To actually do a code review, 3.5.0-beta.4 was release on the 9th June, and 3.5.0-rc.1 on 1st September, so it's looking at all the commits over a nearly 3 month period.

I'm just setting up to run the tests, which involves swapping the X axis on my printer! Don't worry, it was due an upgrade.

Yeah it's alot of commits/code to read through so I totally get why it's a bitch to track down.

I'll try to disable the filament sensor and see if that makes a difference just for the shits later. Thats pretty much "the only thing" I can't remember trying out this far.

It will be interesting hearing how it plays out for you!

@dc42

Ok so i've tried out a couple other things too now, but it still yields the same result.

• Updated the toolboards bootloader to 2.8, and reinstalled with the binaries mentioned earleir.
• Commented out the filament sensor code from config.g.
• Added M220 S50 to my start gcode so every extruder move is at 50% from the getgo.

Here is the reports from when it's not extruding agian (stopped at the "usual point" in layer 3) :

@Exerqtor you said that if you pause and then extrude manually, it works. Does it work if you send a G1 command that does both movement and extrusion? What happens if you resume the print after the pause?

[Exerqtor]

@dc42 I haven't tried doing a G1 move and extrusion, just extrude and retract with DWC or PD. I'll test that tomorrow.

When i resume the printer after a pause it goes back to the print just like expected except it don't extrude. Pretty much pics up right where and as it did before the pause.

[Exerqtor]

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

Sorry for the late reply but I've been out cold with the stomach flu the whole weekend 🤮💩

---

Finally got around testing this today though! So I made a macro containing G1 X0.1 Y200.0 F1500.0 E15 that I ran (manually from PD) while the printer was paused after it had bugged out during the test print (printhead moves to X/Y0 when paused) and this is what happens:

• The printhead moves to Y200, but don't extrude anything.
• I try to manually extrude 20mm @ 5mm/s, through PD and that works.
• I manually jog the printhead back too X/Y0 and try to run the "G1 macro" once more, with the same outcome ast the first time i tried.
• I then manually extrude another 20mm with PD, that works.
• Tries to resume the print, and it goes on like every other time with all movement and no extrusion.

Here is the reports from when it's resumed after runing the above tests:

@droftarts, how did your test turn out btw? If you've found the time to do so yet

[droftarts]

@Exerqtor sorry, it’s taken me a bit longer than expected to update my machine. Apparently linear bearings need lubricating at least once every 10 years! However, it’s back up together, the 1LC is wired up to a Hemera, just need to finish off commissioning and testing, then I can break it again trying to emulate your setup!

@droftarts no need to excuse yourself! 😅 Yeah those darn rails and their demands lol.

Take your time, I still fall back to 3.5.0-b4 every time I need to get something printed. But it would be really nice to find and fix the issue before the next rc *wishfull thinking* 😇

@Exerqtor thanks for running that test.

I'm starting to think that the issue must be with the main board firmware, because the tool board only sees the extrusion movement command and has no idea whether there is axis movement as well. Have any of the tests with different firmware versions established which firmware affects the symptoms? For example, if you revert the tool board firmware back to 3.5.0-rc.1 or rc.2 (or even b4) but keep the main board firmware at rc.3+, does the symptom change? I suggest you disable your filament monitor during these tests to avoid incompatibility issues.
