Duet 2 Wifi with generic Max31865

KeithW

Hi All,

I just want to confirm what I am doing is ok and correct and to get some help with some configuration.

I have upgraded my Duet 0.8.5 with a Duet 2 Wifi running Firmware 3.11. I already had a generic Max31865 for my PT100 sensor and want to continue using this with the Duet 2 as it works OK.

Previously I have it connected to the 50 pin connector as shown here. Now on the Duet 2 WiFi I have it connected as follows.

Is this correct and how do I go about telling the Duet which channel to use? Would is be as simple as adding this

 M308 S1 P"spi.cs0" Y"rtd-max31865"

to the config.g and what M950 command would assign it to the hot end?

Thanks

Veti

M308 S1 P"spi.cs0" Y"thermocouple-max31856" ; 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
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H1 S280 ; set temperature limit for heater 1 to 280C

M563 P0 D0 H1 F0 ; define tool 0
