irmware for the wifi module didn't flash properly. You can usually resolve this by connecting via USB and using
M587: Failed to add SSID to remembered list: another SPI transfer is pending ist the original Error
M997: File 0:/firmware/DuetWiFiServer.bin not found is the Error.
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

old code

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. -

Did you see my previous reply?

I have say thanks for great help!!! But somehow I am completely lost.
The old config worked except for the beforlast termistor (I changed it but should be OK)
Now I checked the wiring! 87d3ed42-0e46-4a99-b7dd-e0b7291af44d.jpg
What are these 2 small PCBs on top?
E0Temp
PCB lower
PCB upper
E3Temp 150Ohm
I think I did not get how it works...
Here is my old and new config

Those look like PT100 daughterboards. If that's the case, those are not thermistors, but PT100 sensors, an your config needs to change.

I do have some severe mismatches with the pins, and it will take a while for me to understand this (coding), but wouldn't it make sense to remove the daughterboards?
-
@MIke-1 said in Thermistor 104nt-4-r025h42g:

No, then you would have to remove the PT100s as well and replace them with thermistors.
The coding part isn't very difficult, really. The only thing that needs to change is the M308 lines that describe the sensor setup to the firmware. Right now it's telling it it's a thermistor.
It would help to know exactly which sensor is connected where. I can't quite tell from your photo, but it looks like you have a resistor and a pair of wires connected to the bottom board, and 4 wires connected to one of the top. Can you verify what is connected where?
If nothing has physically changed hardware wise from when your previous config was used we can infer that channels X200, X202 and X203 were in use.

Unfortunately not much of a difference
This is the old setup wich worked except the 3rd thermistor.

@MIke-1 you response is confusing me, it looks like you have thermistors in your original confit but PT100 boards installed, one of the PT100 board has a resistor in it as a reference.
Please can you confirm which wire goes to what hotend and where its currently plugged in for all of the temperature sensors (except the bed as that looks like its working). Once you have that. measure the resistance across the sensors to see if they are 100K (thermistors) or 100R (PT100).
