DWC Seems to Crash After Uploading a Print

clegg78

@ccs86 So... I may have stumbled on something in my case today... Disabling both filament sensors (Duet rotating magnet ones, one on each print head) = no reconnections/DWC crashes.
Enabling one = some random drops.
Enabling both = Crashes galore.

I am going to be doing more testing on this.

CCS86

@clegg78

I'm actually using no filament sensors. Just a BL Touch.

clegg78

@ccs86 Interesting. I also have a BLTouch. curious what bug was introduced in 3.4.0 to cause these weird behaviors.

CCS86

@clegg78

Have you tried downgrading RRF? That's my next step.

clegg78

@ccs86 I have not. My machine is used for pretty consistent production use and the DWC thing is annoying, very annoying, but hasn't been a show stopper for it to run. And the code/config tweaks for 3.4.0 I don't want to unwind. I guess if it turns out there is no fix, I may have to go back.

CCS86

@Phaedrux @dc42

We might want to move this thread.

I just flashed back to RRF 3.4.0 RC1 (DWC 3.4.0 stable) and the issue vanishes.

dc42

@ccs86 is this still on Duet Maestro?

CCS86

@dc42 Yes

dc42

@ccs86 please provide your config.g file and any other macro files that it calls.

Do you need anything else @dc42 ?

@dc42

Does 3.4.1 have any potential improvements for this issue?

I'm not sure, but worth testing with the latest code base regardless.

Bug seems to be gone in 3.4.1 RC1

Thanks for confirming this. Based on your report and on another one on a Duet 2, I suspected that in some configurations parts of the object model might be getting too large to fit in the available buffer space to send to DWC. So in 3.4.1 I increased the buffer space on Duet 2 and Maestro, and shrunk the object model data a little.
