RC Servo position controlled by slicer fanspeed
-
I'm currently in the process of building a 90°C heated chamber 3d printer with 2 independent xy gantries for dual extruder use.
Using a duet2wifi and duex5 and am currently working on the chamber heater and "part cooling solution" (with hot chamber air) and I'm wondering if it's somehow possible to control a the position of a RC servo via fanspeed from the slicer to control a flap.I haven't really found anything online regarding that topic yet. Input is greatly appreciated.

@vogel25 you could use daemon.g to set the servo position, using the fan speed looked up from the Object Model.

@droftarts My impression with partcooling fans is: they are already too late, because the fan needs to spin up.
Now adding another delay by using daemon.g makes things worse eg. for bridging.
IIRC a lookahead strategy is possible with the multi gcode planner, but how? -
@vogel25 you could try setting the PWM frequency to 50Hz and use the M106 L and X values to set the PWM range to values that RC servos understand.
