Missing extruder steps with Duet3 6HC/3HC

dc42

@medicusdkfz, the remaining issues with extruders connected via CAN bus that we are aware of have been resolved in the 3.3beta source code. Please update to 3.3beta3 when we release it, which we expect to do next week.

@dc42

In preparation for its release, how would one update to a beta firmware with a duet 3 in SBC mode?

Thanks.

See here for adding the unstable branch repository.

@phaedrux I assume as I already have a working setup, I just need to add the unstable source and then the sudo update stuff. Correct?

What about the expansion board firmware, will that be downloaded with the update and then follow the update procedure for expansion boards.

Thanks.

Phaedrux

@Rushmere3D Yes, add the repository and update as usual.

The expansion boards should be updated automatically as well, but check them with M122 B1, etc and update them manually if needed with M997 B1, etc

Note this from the documentation linked:

In case you were using the stock package feed, make sure to remove it before you run apt-get:
sudo rm /etc/apt/sources.list.d/duet3d.list

same applied is reverse when switching back to the stable feed - remove the unstable one

Thank you for this answer. But itˋs not so easy... I lost my confidence with the beta firmware, because I had to much trouble with my Duet combination at my Voron. And I thought, it was me... Thinking to give the SKR boards a try especially with the multimaterial option (9 colors) for the Voron 2.4...

@dc42 Has this firmware been released yet?

Thanks.

@rushmere3d 3.3 beta 2 is available.

https://github.com/Duet3D/RepRapFirmware/releases/tag/3.3beta2

and there have been some early test builds for beta3 on DC42s dropbox link.

I think Beta3 should be just around the corner.

@phaedrux I actually updated to 3.2.2 today and so far it's fixed the issue I was seeing.
