@dc42 Thank you! The K"J" parameter did the trick, it works prefectly
I saw it was also changed in the documentation
I noticed one more place (in the new docs) where it could be changed, Im sending the picture and link: https://docs.duet3d.com/User_manual/Connecting_hardware/Temperature_connecting_thermocouples

Otherwise we can mark this topic as solved

Thank you again

@dc42 thank you, I’ll give it a try today

@aronmeszaros is there something wrong with my syntax or it could be because of the firmware version?

@stefvandermeer it sounds like a wiring problem, try with another thermistor or check the sensor pin position if it is really the one that you connected it to

@fabian-du Are you connecting the Nema 34 directly to the duet board?

Hello, I would like to configure a J type thermocouple with the following command: M308 S8 P"1.spi.cs0" Y"thermocouple-max31856" T"J" A"Nozzle" . It throws the following error: M308: expected number after 'T'
Type K works just fine I have 3 of them working. The TC boards are on an expansion board thats why the 1.spi
Im running: RepRapFirmware for Duet 3 MB6HC version 3.4.0beta6 (2021-11-06 11:38:57) running on Duet 3 MB6HC v1.01 or later (standalone mode)
Im afraid to upgrade because there were a lot of things that were not working after this update and this version had the combination where it all did

@t3p3tony Only VIN power is applied nothing else and I double checked the power supply

@dc42 Thank you for the reply, Im afraid the MCU is blown because this issue happened right after a short circuit that was accidentally made on a CN1 port of a servo drive
That could have forced 24V into the StepDir pins of the expansion board and burn the MCU;
Btw its Slovakia, Bratislava

@zapta Digital resistor is a very good idea, it gave me an inspiration, thank you

Ive been using 3 EXP1XD boards with the Mainboard 6HC for a while. Suddenly one of them stopped blinking. Only the 5V light is on. The Status and the green light are all off when I turn the board on.
I tried to reset the board with jumper wire but no help. The status light should be blinking and show an error code based on the flashing frequency but there is no documentation about what does it mean when the status light refuses to turn on.

I suppose there must have been an overcurrent acting on the pins from an industrial servo driver that might have caused this issue

What do you think? Is there something I might try before throwing it to the trash?
