Cannot get the print fan to come on

Hi,

Anycubic Delta Linear + with duet 3d and smart effector

I can't for the life of me get the print fan to come on. I've unplugged it and held it against the 'always on' connectors and the print fan springs to life so i know it's not broken

I currently have the hot end fan plugged into P0, and the print fan connected to P1. Is it my settings. Is my Duet3d connection broken. If I had hair I'd be pulling it out. Here's the important bit out of my config.g:

; Heaters
M305 P0 T100000 B4138 C0 R4700 ; Set thermistor + ADC parameters for heater 0
M143 H0 S120 ; Set temperature limit for heater 0 to 120C
M305 P1 T100000 B4138 C0 R4700 ; Set thermistor + ADC parameters for heater 1
M143 H1 S280 ; Set temperature limit for heater 1 to 280C

; Fans
M106 P0 S1 I0 F500 H1 T45 ; Set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned on
M106 P1 S1 I0 F500 H1 T45 ; Set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on

; Tools
M563 P1 D0 H1 ; tool 0 uses extruder 0, heater 1 (and fan 1)
G10 P0 X0 Y0 Z0 ; Set tool 0 axis offsets
G10 P0 R0 S0 ; Set initial tool 0 active and standby temperatures to 0C
M501

thanks

You have both fans set to thermostatic control.

Our intention is that you use Fan 0 for the print cooling fan and Fan 1 for the heatsink fan. This is easiest to set up in firmware, and is how the firmware uses the fans by default.
