I created a fan output with
M950 F4 C"PE3" Q100
M106 P4 S0 H-1 L50 X255 C"CPAP"
But when controlling it S[1-50] all set the speed to 50, which makes some sense, as L told it it should start at 50, but is there a way to make it so S0 is off, S1 is converted to 50, and everything from S1-255 is mapped to return 50-255 instead?
My hope is to be able to control the fan normally from S0 to S255, and it then be mapped to something like
M106 S0 > 0
M106 S1 > 50
M106 S2 > 51
