Toolboard + fixed fan

tecno

How do I change following to have the tool fan always on! No M106 to touch this !!!

M950 F1 C"121.out2" ; // TOOL FAN
M106 P1 S1 H-1 ;

Must be 100% ON >>>> NO M106 to tamper this

As there is no power output=Vin connector need to have C"121.out2" to do this for me.

I think I have a solution for my needs, please correct me if I am wrong.

M950 P0 C"121.out2"
M42 P0 S1

So why a problem, S3D posts gcode with M106 S0 and I do not want to manually edit each and every print I want to do.

If you used OUT1, you could use the GND pin rather than out1 and you should have an always on fan.

Out1 is set for part cooling, yes it would be so as you describe but I am out of these bloody miniature crimp connectors so a switch is not possible
