4028 fan speed control reversed

I have encountered a problem with my 4028 fan. The fact that the fan runs at 100% after boot up is known to me. The problem is that the fan only goes off when I set the fan speed to 100%. If I set the fan speed to 0%, the fan runs at full speed. This makes me think that it is reversed. Can I change this in the software or is this a hardware error in my wiring?

https://os.ratrig.com/docs/guides/4028#pwm you probably forgot the ! in the example code:
[fan]
pin: !fan_part_cooling_pin
[fan]
pin: !fan_part_cooling_pin

Thank you very much. I'm glad it was my fault and not a hardware problem. I followed the wiring instructions and then the RatOS configuration. It didn't occur to me that I needed to add anything to my printer.cfg file. Maybe a note in the cabling instructions that you need to change something in the printer.cfg file would be helpful.

Not sure what you mean, Rat-OS doesn't have cabling instructions

I followed the cabling instructions found here: https://ratrig.dozuki.com/Guide/12.+Wiring+Firmware+&+RatOS/143

RatRig the company created that. Rat-OS was made by Mikel. They are not the same thing
