Fan remapping
-
I am having trouble mapping fans. I don't know why but it is so time consuming for me.
I have two extruders E0 and E1.
I have two blower fans(part cooling) for E0 and E1.
I have two fans (parallel wired) to keep the heatsink cool which is temperature cooled(T45)Basically heatsink fans not working with the temp control.(connected to FAN1 on board) What I am missing here?

@secure said in Fan remapping:
M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency
M106 P1 S0 H-1 T45For a thermostatically controlled fan you need to day which heater its monitoring so not H-1 but H1 and/or H2

You mention you have both heatsinks cooled by one fan pin so this, untested, may work:
M106 P1 S0 H1:2 T45

@secure your fan mapping looks wrong
; Fans M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency M106 P1 S0 H-1 T45 ; set fan 0 value. Thermostatic control is turned on M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency M106 P0 S1 H-1 ; set fan 1 value. Thermostatic control is turned off M950 F2 C"fan2" Q500 ; create fan 2 on pin fan2 and set its frequency M106 P2 S1 H-1 ; set fan 2 value. Thermostatic control is turned offyou have the M106 for P1 before the M950 for F1.
you should probably have this; Fans M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency M106 P0 S0 H-1 ; set fan 1 value. Thermostatic control is turned off M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency M106 P1 S1 H-1 T45 ; set fan 0 value. Thermostatic control is turned on M950 F2 C"fan2" Q500 ; create fan 2 on pin fan2 and set its frequency M106 P2 S0 H-1 ; set fan 2 value. Thermostatic control is turned offNote the layout change.
I've also inverted your S values on each M106 as they were incorrect
You should then map F0 and F2 to your tools in M563
This is of course assuming that fan 0 and fan 2 outputs are your cooling fans and fan1 are your heat sink fans
