Error: Temp reading fault on heater 1: unknown sensor 3.3rc1+1

appjaws

I have installed a PT100 Daughterboard and a PT100 sensor but I am getting the following error:-
Error: Temperature reading fault on heater 1: unknown sensor

This is the config entries:-
M308 S1 P"spi.cs1" Y"rtd-max31865" ; create sensor number 1 as a PT100 sensor in the first position on the Duet 2 daughter board connector
M950 H1 C"spi.cs1" T1 ; create nozzle heater output on e0heat and map it to sensor 1

Perhaps I have misunderstood the instructions, do I need any other config entries?

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

Updated firmware but still have the same error.

@appjaws Can you confirm firmware version with M115?

@phaedrux
M115
FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.3RC1+1 ELECTRONICS: Duet Ethernet 1.02 or later + DueX5 FIRMWARE_DATE: 2021-05-01 21:43:27

Thanks for confirming.

@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.

@phaedrux
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.

Glad it was something simple.
