Adjusting part cooling fan speed turns off extruder fan
-
I have my extruder fan (Fan 1) thermostatically controlled, and my part cooling fan (Fan 0) set up to just run when instructed to do so by the user or gcode. When the hot end gets to 50C the extruder fan turns on most of the time but sometimes will just sit there and hum. To make matters worse, when I adjust the speed or turn off the part cooling fan, it shuts off the extruder fan, even though the extruder is at full temp....
Any ideas?

@wrenches adjust your M563 and remove the 1 from F.
You should only map your cooling fan to a tool -
@jay_s_uk thank you for your help, it works as it should now
