Hi, I have been having some problems the out7 out8 out9 pins getting to turn on. I am using a 24V power supply. Can someone help me determin if those ports are fried? Thanks

What board are you using? What firmware? What gcode are you sending? What do you have connected? How is it connected?

@Phaedrux Its a duet3 board the firmware is RepRapFirmware for Duet 3 MB6HC version 3.4.1

I try something like this:
M950 F0 C"out8" Q500
M106 S127
M106 P0 S200 H-1

I tried the slider tool too and no dice

@rister502dad Fan 0 on out8 is set as a thermostatic fan so it will only turn on when the hotend is above 45C, however you have an S0 in there which is either invalid or will prevent it turning on at all.
