Your advice works out. It had to do with the Z parameters. I was using Z:16:16:16:16
After changing it to Z:16, the error message is not shown anymore!

My Extruder steppers still do not shown amperage yet.

For me it now works!

Used another cable to another surface tablet on a docking station, and it worked!

Don't know if it is the cable or the docking station. But I'm happy to see it work!
Interestig to see that when the printer is switched off but connected to the surface, the genuine BL touch lights up.

Thanks for the support,

Harald

@Phaedrux @Veti
Phaedrux, your suggestion was to ask for a warranty exchange.
I did ask for the exchange, the company seemed to be not too willing to help out. Luckally they checked with the people of Duet3d and I could exchange my controller board.

Although the card seemed to be used already, the problems were over. My four Z-motors are finally working correctly without any flaws.

It was somehow surprising to see that the temperatures measured by the NTC's were significantly different, although I used the same parameters as before. But that is a next step.

Thank you very much for your help solving my problems! Again many thanks!

This topic can be closed, problem solved!

It finally worked !
Updating the Pi sd card to the latest version, finally did it. It is connected to the duet3 again, great!

Also surprisingly this time my pi asked me to update the firmware something it did not do before. So now I upgraded the Duet3 to version 3.1.1 and updated the RPi too.

Now updating firmware of the three expansion boards

Thanks for the help

@Phaedrux @dc42 I think it is best to close this thread. My board is found and updated.
I will open a new thread for other problems like homing.....

@Phaedrux Yes I will, thank you again!

@Phaedrux

Uploaded the config files for my setup and connected again.

Problem solved!

Thanks a lot Phaedrux
