Check your slicer for fan settings. If it's Cura, check the printer profile. It looks like you have it set to command Fan1.

M106 S127.5 P1

Note the P1.

Glad to hear you got it sorted.

Ok so last night, got my temps to work. I realised that when they were working, I was on older firmware 3.1.4, but then I recompiled to the latest trying to sort my homing issue, which killed my temps. Here is the heater config which is working perfectly. I may try and update to the latest firmware and use this same heater configs.

; Heaters
M307 H0 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit
M305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M305 P1 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 1
M143 H1 S300 ; set temperature limit for heater 1 to 300C
M305 P2 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 2
M143 H2 S300 ; set temperature limit for heater 2 to 300C

So final issue to solve is this BLtouch. I have triple checked all of my wiring and its correct as per the duet3d docs.

you can't brick the range of duet products that have atsam chips by programming them as the bootloader is in read only memory.

(ir sensor, smart effector and the filament sensors that uses attiny instead of atsam chips are exceptions, where you could in theory mess up programming fuses)
