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

[oozeBot]

I just tried to lower the routine to a 49 point mesh and it still failed multiple times at different locations.

Sigh.. I understand it's a Sunday, but if anyone sees this and has any ideas on how to capture detailed info on the issue before rolling back to 3.2b1 in a few hours, please let me know.

Run the same test but also run DCS in debug mode and capture the output.

@gloomyandy DCS is not an option, unless there is another way?

Sorry should have provided more details. You need to do this on the rPi. This is the official doc: https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3#Section_Monitoring_optional

I'm not sure if that is 100% correct for 3.2-beta3 though. In particular you may find that when you run DCS as root (which this will do), you can no longer connect via the web interface. But you should still be able to run the G29 via the USB console. You may also find that this produces a lot of output so you may find that changing the command to:
sudo /opt/dsf/bin/DuetControlServer -l debug | tee log
will help. This will send a copy of the output to a file called log in your current directory.

@gloomyandy here is the tail end of the output before it fails.. there is nothing valuable. It simply stops:

I tried running M122. It's added to the queue but since G29 is still running, it's blocked from executing. The only way I know out of this is to reboot, which clears any errors.

There may be something in there that is useful to Christian when he gets to look at it, so if you have the full log file please post it for him to be able to look at.

[oozeBot]

@gloomyandy @chrishamm Here is the log. It also contains a bonus crash at line 362-364 where it lost connection and soft-rebooted itself. I hadn't seen that before..

I'm going to be rolling back to 3.2b1 here soon. Please let me know if there is anything else I can assist with testing..

Just to add some data to this thread, I'm able to finish 210 point Mesh Probing on Duet3 with Toolboard with no SBC running 3.2 beta3:

09/11/2020, 12:27:29	210 points probed, min error -0.063, max error 0.349, mean 0.079, deviation 0.085
Height map saved to file 0:/sys/heightmap.csv

Thanks, that's a very useful data point. Looks like it's something to do with running the deploy/retract files when they are held on the SBC, because the rest of the G29 probing function doesn't involve the SBC except at the start and end.

@dc42 I still have one machine running 3.2b3 if there is anything you or others want me to test on this issue.

I plan on rolling back to 3.2b1, creating a height map, and the moving then back to 3.2b3 for other testing by this afternoon though.

@chrishamm, is there anything else you would like @oozeBot to test?

I tried it yesterday and it seems to work but from 3.2b2 instead of 3.2b1 to 3.2b3

[chrishamm]

@oozeBot Thanks for reporting this issue, I could reproduce it and I'm testing a potential fix for this problem.

[oozeBot]

@chrishamm great! I didn't get around to rolling this machine back to 3.2b1, so please let me know if you want me to test your fix..

[chrishamm]

@oozeBot Yes, I am quite sure I could figure out what was going on. Please try out this firmware build with DSF 3.2-b3: https://pkg.duet3d.com/Duet3Firmware_MB6HC.bin You can upload it on the System page and confirm the update prompt.

[oozeBot]

@chrishamm This appears to be fixed. I just completed a 196 probe mesh without issue. Thanks!

[oozeBot]

@chrishamm scratch that - while it did complete, DWC is still in a busy state where it will not accept any new commands.

[chrishamm]

@oozeBot Please try to download and flash that file again - I just updated it once more with my other hotfix. If it remains in the "busy" state with that build, please share the debug log of DCS and I'll see what I can do.

[oozeBot]

@chrishamm will do it right now.. thanks

[oozeBot]

it stayed in a busy state. I'll capture the DCS log and upload here soon..
