Nidec 4028 Fan
I have a Nidec fan it is connected and working properly. The tachometer reading I get is always 0 RPM (in red) even when the fan is running. This is how I have it in my config. Have I missed something?
pin: !fan_part_cooling_pin cycle_time: 0.01 enable_pin: PA9 tachometer_pin: ^PD13 tachometer_poll_interval: 0.0005

check your fans datasheet for the specific tachometer specs.
Refer to this section for tachometer configuration options: https://www.klipper3d.org/Config_Reference.html#fan
Thanks I will let you know when I have it sorted.
I have the tachometer working now. The issue was I had it connected to a fan header PD15. It is now connected to PG12 which is a 3 pin header and works perfectly.
