      @appjaws there's RC1+1 available here https://forum.duet3d.com/topic/23025/software-package-3-3-rc1-released/2
      Please upgrade to that

      Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

                @phaedrux Do you think I have the correct entries in config.g?

                Just to let you know, I also have installed an accelerometer:
                ; configure accelerometer
                M955 P0 C"spi.cs3+spi.cs4" ; configure accelerometer

                  @appjaws said in Error: Temp reading fault on heater 1: unknown sensor 3.3rc1+1:

                  M950 H1 C"spi.cs1" T1 ; create nozzle heater output on e0heat and map it to sensor 1

                  Actually, no.

                  Where do you have the heater physically connected?

                  M308 S1 P"spi.cs1" Y"rtd-max31865"             ; configure sensor 1 as thermocouple via CS pin spi.cs1
                  M950 H1 C"e0heat" T1                           ; create nozzle heater output on e0heat and map it to sensor 1
                  

                  Should be e0heat rather than an spi pin. The SPI is for the temp sensor. The M950 needs to be the heater itself.

                    Really strange, that is what I had at first and in trying to solve the problem ended up with the wrong code.
                    I can now report that I have an ambient temperature reported.
                    Thanks for your help.
