Connection issue with 3.5-rc2

chrishamm

@e4d The panel of the temperature graph looks odd to me. Perhaps try to disable your ad-blocker (if any) and if that doesn't help, open the dev tools via F12 and check the JS Console for errors.

@chrishamm my adblocker is already disabled, here's the output of the dev console on 3 differents browser Chrome, Opera and Edge :

@e4d Okay, the new version 3.5.0-rc.3 should have a bug fix for this error message, although I don't think it's the reason why DWC stays in "Connecting". Can you try to upgrade your SBC using apt update/apt upgrade and check if that helps?

@chrishamm thanks for the release, the error message is fixed in the dev console on the browser.

The connection issue was still there sadly. I identified that the issue is caused by the line

M141 H5

If I have it in the config.g file, impossible to connect and when I comment it I can connect on the board as usual. If I comment it on the config, power up and then write "M141 H5" in the console it goes on connection screen.

Is it a known bug or something new ? I can't figure out how to have the control on the heated chamber without using M141 to declare it. Is there a workaround or do you plan a bug fix soon ?

chrishamm

@e4d Is there any way you could provide a minimal config.g that lets you reproduce this problem? I just put M141 H5 in my config.g and after a restart my machine came up as expected.

This config let us reproduce the problem :

To test this I did :

Put this config with "M141 H5" commented
Access the DWC in Chrome browser
Execute "M141 H5" in the console
Refresh the webpage

@e4d Thanks! I could reproduce and fix it. The fix will be included in the next DWC version, so probably 3.5.0 stable.

e4d

@chrishamm thank you for your quick inputs on my issue. Do you have any timeline on the release of 3.5 stable ? I can't use an heated chamber in the meantime ?

chrishamm

@e4d You can replace DWC in SBC mode by uploading DuetWebControl-SBC.zip from here on the Files -> System page. This build should fix the problem again (it was actually caused by the JS error you reported).

e4d

@chrishamm it works well on my machines, thank you again for your time on my issue
