Flashforge CP-dual extruder configuration issues

So I have a duet wifi 1.04 installed and everything generally seems to be working - no prints and calibration quite yet.
I am trying to setup the dual extruders and I am having a bit of trouble with them. I have had fans turn off when the tool was still on.
My config file is here: https://gist.github.com/madebyjeffrey/3318c98e944668b8a51b34fecc949f99
The relevant sections:
; Fans M106 P0 S1 I0 F500 H1 T75 ; set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned on M106 P1 S1 I0 F500 H2 T75 ; set fan 1 value, PWM signal inversion and frequency. Thermostatic control is turned on M106 P2 S0 I0 F500 H-1 ; set fan 2 value, PWM signal inversion and frequency. Thermostatic control is turned off ; Tools M563 P0 D0 H1 F0 S"Left" ; define tool 0 G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets G10 P0 R0 S0 ; set initial tool 0 active and standby temperatures to 0C M563 P1 D1 H2 F1 S"Right" ; define tool 1 G10 P1 X34 Y0 Z0 ; set tool 1 axis offsets G10 P1 R0 S0 ; set initial tool 1 active and standby temperatures to 0C
So fan 0 goes to the left, fan 1 goes to the right. My most recent test of the right extruder had the left fan on and the right fan turned off when the right hot end was hot and the left was below the threshold.
Could anyone guide me as to how I should configure these? I want to be able to do dual extrusion where the fans operate independent of each other and with their respective hot ends. It would be nice to have one of the hot ends to go into standby mode when the other is used to prevent oozing - but I have no idea if this is what I would really want or how to do it.
The parts fan is on fan 2.
@zzing Have a read of:
You have set Fan 0 and Fan 1 up as thermostatically controlled fan for Heater 1 and heater 2 (so far so good). This means they will cool those extruder heatsinks from 75C and higher in your config.
You have then setup tool 0 and tool 1 to use fan 0 and fan 1 as the part cooling fans, really they should (presumably) both use fan 2?
