If you ever do decide to update beyond 2.05...

If you still have access to DWC. Upload these 4 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
https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.0/Duet2and3Firmware-3.4.0.zip

That will get your firmware and DWC up to date.

You can see the change logs here:

For your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.

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.

@dc42 said in Duet2 wifi + Duex5 board thermistor issue:

version

yeah, I saw the beta version, I just went with the latest stable release. I'll have to remember that for when I upgrade.

@dc42 said in Servo on a Duet 2 Wifi + Duex5:

280 P0 S100

Ok, sorry to come back to this post so late but I had other issues and I could not test further...

Now I managed to free other 3 heater ports on the Duex, so I got rid of the buck converter as I could connect all 4 servos to 4 pwm ports on the Duet.
Nothing works anymore.

I tried also this configuration but nothing... The only visible thing that happens when I invoke a M42 or M280 command is that the corresponding heater led lights up (and remains up). So, it could be that the ports do not deliver the 5v? Before, using only the signal pin they worked with an external 5v supply...

Your video is private and I cannot access it.

Can you go through these troubleshooting steps and see how far you can get?

That message is coming from a user macro and not the firmware. What did you push before you got that message?

Hardware seems functional. For further help you'll have to provide some config files. config.g, homeall.g, homex homey homez bed.g and results of M98 P"config.g".
