Just a short update.

My printer is back online, I've been printing happily for the last two days on 3.2.2.

DHT works perfectly fine, no interruptions in printing, no skipped layers, printer comes on immediately.

I'd say all problems are solved! 🙂

Thank you so very much for your help @dc42.

I'll keep monitoring and tinkering with the firmware more, but I expect it to work fine.

@dc42 Okay thanks 🙂 make sense

@dc42 thank you!

Thanks for the update.

@T3P3Tony

Thanks, I'm running the 3.3 Alphas released to address CAN issues and wanted to know if i was safe to backport, as i'm not sure if the Alphas had all of the changes listed for the 3.3 betas in prep.

I promise i read the changelog for both (3.3 beta + 3.2.1), but I wasn't sure if the alpha that i'm running had a changelog.

@dc42 is there a way to properly "flush" the memory on thoses boards ?
I have been working on that issue for couples of weeks now on different setups and boards configuration and it seem to happen more and more often on most of them. I wonder if it could be caused by a bad sector or a bug and because of that spot it just happen more and more. (Sorry for my english here, Im french .. trying to explain clairly..)

Everytime I update/flash the firmware it seem to crash faster too.

At the moment Im down to testing different sd cards, maybe I got some fakes/cheaper cards causing the issue too.

Also important point: the setups I have who never been updated (some benchmarks and extruders tester) dont have that issue. Yet..

Here is a copy of the M122

I tried again to capture before it went into Warn loop but even sitting with wireless keyboard in hand to try and stop the process as soon as the loop started it would clear the putty terminal history.

M122 right after boot

@dc42
Got it back today and all working now, thanks.

@matt3o I see your point; it is not a very fast process and it is worthwhile to know how to tune a PID loop 🙂

Some people just want to build machines and that might be a nice feature for them. The algorithm looks like it performs pretty well...

@dc42 I managed to get it up to 250mm/s before having a memory crash error ( I should had written it down..) but moving 4 stepper + extruding + sending code to the 2x3hc boards at that speed will create issue for sure... and I was also doing a shape, not a square so the file was heavy.. poor board he is getting worked hard. nothing blew up tho !

Yes, I know that you can specify package versions to the be installed that is not really the problem. I still think that this is not the right way to use debian packages.
And it makes no sense from the logical point of view. Why should a later build have a lower version number?
It is clear that this is hard to achieve in classic software versioning, the use of a build number is one way around that. But this has other disadvantages.

Debian is partial helpful https://www.debian.org/doc/debian-policy/ch-binary.html#the-version-of-a-package

I think that the only real solution is to work with a "upstream_version" and a "debian_revision".

One common use of ~ is for upstream pre-releases. For example, 1.0~beta1~svn1245 sorts earlier than 1.0~beta1, which sorts earlier than 1.0.

https://www.debian.org/doc/debian-policy/ch-controlfields.html#id22

Wo not making use of that? Name the package like "3.2.0~Beta4" instead of "3.2.0-Beta4" and you should be fine. [-|~]

Cheers, Chriss

@camcamnz

Thanks,

I have the same issue as you, and I think I have found a lead to solve it. I disconnected the bed and for now, everything looks fine.

@dc42 I can confirm that sending M595 P100 on the 3.3 beta firmware has resolved this issue.
Thanks

@Phaedrux before the auto-tuning I tried a second time manually to see if values changed. In doing so I believe I've found the problem.

The new values are M307 H1 R2.9 C204.0:102.0 D4.00 S1.00 V24 that are very close to the previous ones and indeed I got a fault again BUT it works perfectly if I remove the second C value.

So it seems that at least the toolboard has some issues with the second cooling time constant, removing it solves the issue (or at least it doesn't trigger the issue).

Remains that the duet should not fault without error.

@fcwilt said in Potential bug in release 3.2:

Thank you - that would be much appreciated.

I think the problem is that it seems that no conditional gcode functions are implemented at all in DSF 3.2. Sadly, that isn't documented in release notes.

All of the following fail with a similar message (failed to evaluate 'function_name')

echo "debug " ^ abs(3)
echo "debug " ^ max(1,3)
echo "debug " ^ min(1,3)

Making the assumption that conditional gcode is evaluated on the SBC (and not sent to the duet3 for evaluation,) I searched in github (https://github.com/Duet3D/DuetSoftwareFramework) for the strings of the function names "atan2", "acos" and "radians" and came up with no search results. (The idea was that if the functions were implemented, there'd be at least one matching string literal in the code.
