Javascript error after auto bed compensation

[dc42]

Which version of Duet Web Control are you running? With 2.01 firmware you should use either 1.21.2-dc42 or 1.22.

Firmware 1.21-RC4 is not the same as firmware 1.21 release.

Just updated to 1.21.2-dc42 and still get the error

Any suggestions?

I don't know if this will help, but you could try pressing "Load factory defaults" followed by "Apply settings" on the Settings/User Interface page of DWC.

Thanks, I will give that a shot when I get home tonight. I found it works no problem on my phone this morning so I updated java on my PC but that didn't work. Will report back

[ajcraig99]

Still no luck. It works fine on Edge browser though

Have you tried DWC 1.22, available at https://github.com/chrishamm/DuetWebControl/blob/master/DuetWebControl-1.22.zip (follow that link, then press Download)?

@dc42

Just installed 1.22, no luck.

@ajcraig99 There was a thread here:
https://github.com/mrdoob/three.js/issues/4927

with different possibilities, one of them chrome having problems with WebGL. And one quick check was to call
https://get.webgl.org/
whether this page works.

@joergs5

Thankyou, although my graphics drivers were up to date, I reinstalled chrome which solved the issue.

[JoergS5]

@ajcraig99 That's fine. Sometimes reinstall or reboots solves a problem.

Im getting a similar issue. Though my error reads;

it makes it hard to type in a gcode command to move the head. it does it after bed leveling too. I thought it might have been from my filament sensors but it wasn't from that.

@gnatman your DWC is out of sync with the firmware i think. I would grade to the latest stable firmware and DWC:
https://github.com/dc42/RepRapFirmware/releases/tag/2.01

make sure you read the Whats New file for all releases in between your current one and 2.01:
