    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

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

          @aronmeszaros there was an error in the documentation. The thermistor type letter parameter is K not T. I have corrected the documentation.

          However, you should upgrade to 3.4.0 stable.

              @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
