4028 fan setup MantaM8P 1.1
Hello,
I have been trying for a few hours to get my pwm fan to work.
I can get it to spin at 100% power all the time, or not at all.
Here is my current config for the fan which doesnt work at all.
[fan]
pin:PC14
#tachometer_pin:^PC14
enable_pin:!4p_fan_part_cooling_pin
#tachometer_ppr: 2
#off_below: 0.0
cycle_time: 0.01
#tachometer_poll_interval: 0.0015
#shutdown_speed: 0.0
#kick_start_time: 2.0
Im trying to use the Fan4 and Fan5 headers on the board as I assume I will need one for the pwm and the other to supply power.
If anyone has any idea how I need to wire this and set the config I would greatly appreciate it.

Check the manual, I don't think those 4pin fan headers can handle the amp requirements of the 4028 fan that ratrig uses for cooling
Maybe, Im not sure. Its a 1 amp fan and when I do wire it up so it's always on the thing is just screaming fast
I cant find anything in manual about how to wire up a pwm fan to it
Its a AVC DBTB0248B2G fan
4028 fans default to 100 percent on when they can't get a proper pwm signal
can I test for a pwm signal?
