Do I need to do anything special in ratos 2.1 for a 4028 fan?
I’ve recently upgraded to 2.1.0rc3 and want to add a 4028 part cooling fan. I’m currently using dual 5015 fans and would like something a bit stronger.
Other than the wiring which is covered in the build guide, will I still need to adjust my printer.cfg as such [fan] pin: !fan_part_cooling_pin cycle_time: 0.01 enable_pin: PA9 #using this pin as example Does this need to be added before i install the fan? I had bad luck wiring up my last 4028 and fried it 😦

Yes, you will need to update your printer.cfg to match your changes
Run the configurator again and change the fan to pwm signal insted of input voltage. Either toolboard or mainboard
