M600 Doesn't seem to work with SBC

vishiano

Hello,

I saw the 3.4.0b3 fixed the bug with Duet 3 with SBCs not working with M600. I upgraded to 3.4.0b4 and gave this a try tonight but can't seem to get this to work. The printer does run filament-change.g and then runs resume.g, but then decides to restart the print. Looking at the resurrect.g file shows the printer restarting the print(M23). I have included the relative files below.

This is the console, I ran M122 before I hit resume. After returning to the last position the printer seems to go into resurrect.g and restarts the file.

@vishiano restarting prints instead of resuming them when using SBC is a known issue in 3.4.0beta4. We expect to release beta 5 to fix this later today.

@dc42

Oh, well that's good news! Do you have a list of known bugs somewhere, before I posted I did some searching on this issue and didn't find anything.

@vishiano we only found that bug a day or two ago, so it hasn't made it to a bug list yet. We do sometimes add a "known issues" section to release notes. Eventually they will be moved to github issues.
