Odd Javascript Error causing connection failure

SamanthaJaneyCake

Hi,
Just loaded up the printer to start configuring some stuff and it's thrown the following error at me. It didn't the previous times I booted up but this is the first boot with the bed connected. This error causes repeat failure of connection.

A JavaScript error has occurred so the web interface has closed the connection to your board. It is recommended to reload the web interface now. If this happens again, please contact the author and share this error message:

Version: 1.22.6
Message: TypeError: undefined is not an object (evaluating 'lastStatusResponse.temps.current[heater].toFixed')
URL: http://192.168.0.74/js/dwc.js
Line: 4468:74
Error object: {}

Running on a Duet 2 Wifi w/ Duex5. Thanks for the help!

i think you're using an old version of DWC with a new version of firmware. DWC 1.22.6 is ancient and won't work well with RRF2 or RRF3.

Can you provide the results of M122?

SamanthaJaneyCake

@phaedrux Damn, really? I remember setting this up only a few months ago and everything seemed to be doing okay.

M122 reports RRF V3.0.

I'll look into updating DWC now

If you still have access to DWC. Upload these 3 zip files, one at a time in the system tab. Don't extract them first. Reboot after each. Use M115 in the gcode console to verify the firmware has been applied.
https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet2and3Firmware-3.0.zip
https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zip
That will get your firmware and DWC up to date.

You can see the change logs here:
https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x

For your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.
https://configtool.reprapfirmware.org/Start

Backup your existing config files in the sys folder in case you want to switch back to RRF2. It’s easy to switch back and forth, just upload the zip file for the version you want and then upload your config files.

These documents will come in handy during the conversion.

@phaedrux Thanks for the help. I'm needing to do a full config for everything anyway but need access to DWC first!

Which I can't currently do. Is there a Gcode command I can send in via PanelDue to automate get-latest or do I have to extract the SD and copy directly onto there?

Phaedrux

In this case you should probably just pull the SD card and then extract this zip file into the WWW folder.

https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/DuetWebControl-SD-2.0.7.zip

Then you should be able to reach DWC again and can upload the files as described above.

@phaedrux

I got the DWC onto the SD and got it working so thank you!
Started trying to upload the firmware starting with 2.05.1 and got this error upon trying to restart to implement files:

M997 S0:1
Error: Firmware binary "Duet2CombinedFirmware.bin" is not valid for this electronics

Running M115 afterwards shows it hasn't changed. I had assumed that the relevant files had gone through regardless and the irrelevant failed but I take it that's not the case?

EDIT: According to here I need to rename the firmware bin file. I'm trying that now, bear with me

EDIT: Aaaaand now I can't connect at all. M552 says wifi module is being started. That doesn't change. Wifi LED off, IP not showing on portal. Damn.

SamanthaJaneyCake

New day, new problems. Looks like trying to follow those steps last night threw my wifi module out of sync with the firmware... Now I'm looking into how to fix that...

Phaedrux

Did you upload the zip file as is? Without extracting it first?

Can you send M122 from a USB terminal and post the results? Then we can see what firmware versions are installed and can give guidance from there.

SamanthaJaneyCake

@phaedrux Hello again! I ended up doing a complete fresh reinstall from the configurator then made sure I was using the latest stable release.

Good news is I am now connected to DWC 3.3.0, bad news is I have a new issue here.

M122 printout is being flagged as spam by Akismet. I will try and snippet the relevant.
