Duet 3/Rpi + toolboard on 3.2b3 - G29 fails

chrishamm

@oozeBot Thanks, I use the same commands on my machine with a BLTouch. I haven't seen any more problems with bed probing with the build that I shared before but I admit I haven't tried many conditional G-codes yet.

@chrishamm here is what I could capture before cutting power before it crashed into the build plate. Note that it actually did complete homing Z successfully the first time I tried in this log, but failed the second time. I had tried right before this and saw it fail several ways, sometimes not extending the probe, other times it seems to skip to the next probe point without completing the current probe. Also note this is the behavior in 3.2b2 that I reported which ultimately led to me rolling back to 3.2b1.

@chrishamm I can confirm I was able to probe a bed with 400 points.
I'll check the homing of the printer in the morning once I'm physically in front of it

@chrishamm ok, caught a better crash while running homez.g which I posted earlier. I just let it probe with the bltouch retracted and protected the bed with a piece of cardboard..

@chrishamm last log file for now. This is also from homez.g which I posted earlier. This time, the first g30 completed successfully, it moved to the left side, touched the probe down once, moved to the right side, probed several times, and then moved back to the left side and started probing again, eventually probing with the probe retracted..

log4.txt

Also, could this be related? Note the 0 at the end of deployprobe0.g and retractprobe0.g. It's found throughout the log but only around 1/3 of the calls seem to be wrong - the rest properly reference deployprobe.g and retractprobe.g..

[debug] Macro file deployprobe0.g not found
[debug] HTTP: ==> Starting code G30 Z-99999 ; sets z-height relative to print bed
[debug] HTTP: Disposing macro file deployprobe0.g

[debug] Macro file retractprobe0.g not found
[debug] HTTP: ==> Starting code G30 Z-99999 ; sets z-height relative to print bed
[debug] HTTP: Disposing macro file retractprobe0.g

dc42

RRF allows each Z probe to have its own deploy and retract files. That's why it's looking for deployprobe0.g first before falling back to deployprobe.g.

@oozeBot Thanks for the logs. I'm afraid I could not reproduce any of the out-of-order replies or stack underruns that I could discover in your log - please make sure the Duet 3 firmware is 3.2-b3+2-ch and NOT 3.2-b2+1 or older (check on Settings -> Machine).

The reason for your problem is probably a combination of these issues but I was unable to provoke them on my setup with the latest firmware.

oozeBot

@chrishamm crap - it appears I am on 3.2-beta2+1. I just ran sudo apt update / upgrade again but nothing new was installed. I also ran M997 from DWC to make sure I updated the firmware.

What am I missing? I'll try to upload it directly to DWC. I'm sorry to have wasted any of your time on my mistake..

oozeBot

After downloading the firmware from the following link and uploading it through DWC, it has now been properly updated. I don't know how that was missed or even installed as I was on 3.2b1 and upgraded to 3.2b3 (skipping 3.2b2) - none of the 3.2b2 resources should have been available to install..?

https://github.com/Duet3D/RepRapFirmware/releases/tag/3.2beta3

It is now properly homing. I am moving forward with a few more mesh bed leveling tested before calling this complete.

@chrishamm said in Duet 3/Rpi + toolboard on 3.2b3 - G29 fails:

@oozeBot I've updated my experimental Duet 3 MB6HC binary again because I found one more potential problem in it.

Please upload this file on the system page and confirm the update prompt.

oozeBot

@chrishamm Sorry - it is very early here and I haven't had any coffee.. I now recognize I've been manually updating RRF at your request.

I just updated the file directly at the link you've provided - it reverted to:

Board: Duet 3 MB6HC (MB6HC)
DSF Version: 3.2.0-beta3
Firmware: RepRapFirmware for Duet 3 MB6HC 3.2-beta2+1 (2020-10-02b1)

oozeBot

@chrishamm OK, I'm now properly caffeinated. I just tested everything again and can confirm the RRF firmware you've linked to is 3.2B2 - not 3.2b3. Any thoughts on this? Was the wrong file uploaded?

chrishamm

@oozeBot Sorry, I uploaded an old file - the build configs have changed recently. Please try to download the file again.

oozeBot

@chrishamm thanks. I'm now on RepRapFirmware for Duet 3 MB6HC 3.2-beta3+2-ch. I'll run through several tests and report back..

edit - homing Z is now functioning properly.. on to mesh bed leveling.

oozeBot

@chrishamm 400 probe mesh completed without issue! System is back to idle. Going to run through it once more and then print something, but overall, it appears the issue is resolved..

oozeBot

@chrishamm I have run through this several times now and feel I can safely report it has been corrected. Mesh Bed Leveling is now successfully completing and returning to an idle state. Thanks

oozeBot

@chrishamm @dc42 - I probably should start another thread for this, but will you please review the attached log to see if anything stands out? I have a job to test bed leveling that I've attempted to run five times now after completing the mesh. The log captured two of those attempts.. something is happening where it randomly loses position very rapidly during non-print moves. I don't know how better to explain it.

I can say with certainty that I've never seen this type behavior before 3.2b3.

Thanks

I just rolled back to 3.2B1 and ran the same job. It completed successfully the first time. With 3.2B3, it couldn't make it past the first layer before drastically losing it's position in X&Y.

@chrishamm - Please let me know how I can help test and identify this issue if it was not captured in the log I just provided.

chrishamm

@oozeBot Can you please explain what you mean by losing its position during non-printing moves? At first glance I couldn't spot anything significant in the logs but I'll have another look tomorrow.

In any case it would help to get a step-by-step instruction on how your problem can be reliably reproduced.

@chrishamm Here are three videos taken back to back after upgrading again to 3.2B3 and installing your latest RRF firmware (3.2-beta3+2-ch). This is the same gCode, which works just fine on 3.2B1, but failed all three times at different places - none making it past the first layer.
