@MIke-1 Maybe you are new to RepRap, but your firmware is from the Stone Age: more than 4 years old. So don’t expect too much enthusiasm to support you with that old bone.
I saw a lot of changes in the gcode form Version 2 to Version 3. That scares me. The system was in a very bad condition when I bought it. Homing and all the coordinates for the toolchanges are messed up. I do have 2 Hemera and 2 bowden printheads. Homing is either done with the printhead (Hemera) or the toolchanger (bowden) hitting the frame... 2 tools work....OMG
With a tool changer, you really will benefit from the latest RRF versions - this forum will guide you through the upgrade procedures if you need help.
I am scared of naming the ports and updating many files. Is it only the config file?
To your thermistor: did the old M305 Gcode work? The X parameter looks strange, didn’t ever use that in my old config files.
It looks like no changes in the config file or comand line work....
2000°C are measured.
However, a readout of 2000°C means most likely a short in your wiring. So please check that.
The resistiance is 150kOhms and I used the old thermistor that still workes. I switched because the old one is too weak or the PID failed as well...so it should be software.
Just let me know your oppinion. Thanx!!!

With a reason. When I updated my printer from 2.05 to 3.3, it was a long run and took me to re-write most of my config and the macros. The good thing is: @Phaedrux has a helpful text module with all the necessary steps listed
The resistiance is 150kOhms
Did you measure that at the board or the thermistor itself?
A resistance of 150k is not very plausible: having looked up the 104nt-4-r025h42g, its nominal values is 100k (at room temperature). Or do you live in an especially frosty environment?
The reading "2000°C" is the maximum value to display, it corresponds to a very low resistance of the thermistor - that's why I can imagine a short as plausible reason.
so it should be software.
I can think of a quirk with the tool definition in your config, so please post your config.g (use the </> tag from the editor). BUT: as you run a very outdated version of RRF, I might be unable to give good advice

You can find an example config for a RRF3 tool changer here: https://github.com/Duet3D/RRF-machine-config-files/tree/master/E3D_Tool_Changer/dc42-duet3-centreZero-2Titan-2Hemera
If you still have access to DWC. Upload these 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/3.4.5/Duet2and3Firmware-3.4.5.zipThat 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.xFor your config, might be a good idea to run through the configurator tool and generate a fresh set for RRF3.
https://configtool.reprapfirmware.org/StartBackup 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.

I think I got the message.
-So I will copy the sd card.
-Run all firmeware updates.
-Use the configurator
-Make a lot bugfixingWill most likely need your support!
It will take a few month...
Is it going to work?

Now it is flashed to 3.3. Everything including WiFi is gone. Will have to fix this next.

It's possible the firmware for the wifi module didn't flash properly. You can usually resolve this by connecting via USB and using YAT to send M997 S1, or if you have a PanelDue just send M997 S1 from the console. That will trigger a reflash of the wifi module.

What went wrong. Such a dictionary is not existing on the sd card.Just copied the files...now on the best way to 3.45

The 3.3 update adds a firmware directory. Either the directory creation failed or the firmware update looked there before it was created. Once you're passed 3.3 it's not an issue anymore.

Made it to 3.45 now
I finshed the configurator and now want to use this as a basis to build it all up.
The config is quite strange. I have issues with M950 and I think I mess up channels.
Here is a section for the Z-Probe:

M950 uses pin names. You can learn about them here: https://docs.duet3d.com/User_manual/RepRapFirmware/Migration_RRF2_to_RRF3#pin-names

M557 X15:385 Y15:385 S40Does this make sense? The cable is linked to the z-endstop on the board.
Is P7 the motor because ist should be P2 as it is linked to the barod's z-axis ?
-
No P is the probe type.

@Phaedrux
Made some progress. I uplaoded files without any magic smoke.
But the last 3 termistiors do show -273°CAny idea what it could be?

Can you show a screenshot of what you mean?
Can you send M98 P"config.g" in the gcode console and copy paste the results here?

If you get a temperature of -273°C, this indicates an open circuit, i.e. nothing is connected to the defined pins:
Check that the temperature sensor is connected to the correct pins
Check the wiring for breaks
Measure the resistance of the wires that connect to the Duet, and that it corresponds with what the firmware expects
Check that the configuration is set correctly for the temperature sensor. -
