Thank you Tony.
It works with RRF3.4.0 B5 with the "-" removed...

Using a Duet 6HC motherboard + Duet 3HC daughter-board, 2 thermocouples connected to the thermocouple board V1.1 on the 3HC
Firmware Version: 3.3 stable June 16

Configuration of Thermocouples :

M308 S1 P"1.spi.cs1" Y"thermocouple-max31856" K"k" ; configure sensor 1 as thermocouple on pin sp1.cs1  expansion board 1
M950 H1 C"1.out0" T1                               ; create nozzle heater output on 1.out0 and map it to sensor 1
M143 H1 S498                                       ; set temperature limit for heater 1 to 498C
M307 H1 B0 S1.00                                   ; disable bang-bang mode for the nozzle heater and set PWM limit

M308 S2 P"1.spi.cs0" Y"thermocouple-max31856" K"K" ; configure sensor 0 as thermocouple on pin sp1.cs0  expansion board 1
M950 H2 C"1.out1" T2                               ; create nozzle heater output on 1.out1 and map it to sensor 2
M143 H2 S498                                       ; set temperature limit for heater 2 to 498C
M307 H2 B0 S1.00                                   ; disable bang-bang mode for the nozzle heater and set PWM limit

It worked fine with RRF3.2.2

I switch to RRF 3.3, I get the error message :

M308 S1 P"1.spi.cs1" Y"thermocouple-max31856"
Error: M308: string too long

The heaters switch to error status

Tried with RFF 3.4.0 Beta 4, same error.

Switch back to RRF3.2.2, everything is OK...

What am I doing wrong?

Thanks, the printer is not at the office, I'll test tomorrow, and post the results.

Thank you

Installed RRF 3.2.0beta4 + DWC 3.2.0beta4 on an machine :
Duet 3 6HC + Duet3 EXP3HC (controlling 2 heads + Bed leveling) + SBC RaspberryPi4 + 7 inches screen, Pi4 powered by a 5A power supply

Since I have installed DWC 3.2.0beta4 on the SBC, the configuration of Pi camera (that worked fine before) disappeared.
Impossible to find out what was the previous configuration, does somebody can help me ?

What is the WebCam URL to enter when using a Pi Camera ?

The log of Pi :

Note : I have checked the header of GCode is the same than the GCode printed last night i doesn't give macro SBC error...

I call my customer, take the control of the pi and send you the log soon...

Note : it seems to appear only with the 3.2.0beta4

I don't use start.g
