Issue after updating 3.4 beta 6 to 3.4 RC1

flopo76

I made update from 3.4 beta 6 to 3.4RC1 and DWC not show the print progress. Need F5 refresh page to show the progress or printer stats. On the 5i screen with 3.4 pre1 seems all ok.

With DWC 3.4 beta 7 works......

Phaedrux

Did your DWC get updated as well?

flopo76

@phaedrux yes DWC 3.4 RC1 but not work. I'ts very slow and freeze after few moments.....back to beta 7

Phaedrux

Standalone or SBC?
What Duet board?

flopo76

@phaedrux Duet 3 Mini 5+ Standalone

Phaedrux

What browser? Can you try clearing your cache?

flopo76

@phaedrux Hello cache cleaning and tried other browser. Same thing,DWC 3.4RC1 i'ts very slow and not show the print stats,only if i made F5 page refresh.My browser is Chrome.....

dc42

@flopo76 are you running with attached SBC, and also using M80 or M81? We have found an issue with this combination that causes some DWC fields not to be updated.

flopo76

@dc42 I'm in standalone and yes i use M80 and M81 with on/off module

@flopo76 Please open the JS console via F12 and check for JS errors when you get performance issues. DWC should not be affected by the M80/M81 bug seen in another thread.

@flopo76 Thanks, please upgrade to this DWC version: https://pkg.duet3d.com/testing/DuetWebControl-SD.zip Then please try to reproduce the problem and check the console again. If the same bug occurs as seen from your log, you should get an extra Failed to parse response: message in the JS console. Please right-click that message and copy it to clipboard, then paste it here.

@chrishamm Updated the DWC no print stats. On 5i display all ok.
