Output_pin display name in GUI?

Your case is not a trivial one, and it would have been clearer from the beginning if you had followed the required template

  • You seem to be using a Creality K1
  • Creality is using a modified Klipper version
  • Your fans are deeply embedded into macros
  • As @theophile pointed out, they are defined as PWM out pins:
[output_pin fan0]
pin = !nozzle_mcu: PB8
pwm = True
cycle_time = 0.0100
hardware_pwm = false
value = 0.00
scale = 255
shutdown_value = 0.0
  • You can rename them, but it likely requires renaming every occurrence of fan0 etc or otherwise your macros will no longer work
  • If you give them a name like My_Cool_Fan then the webinterfaces are clever enough to rename them to My Cool Fan

To make it clear: This is not a Klipper limitation but comes from the special way Creality chose to define this
