Connecting a 4028 fan | RatOS
4028 server fans are becoming a popular option for part cooling because of their light weight and great pressure and flow rates. In this guide we'll go over how to connect one and use it for part cooling. 4-pin fans usually aren't used in 3d printers, and many boards only provide 2-pin ports, but fear not! There's always a way.
invert the pin
yes i tryed
[fan]
pin: !fan_part_cooling_pin
cycle_time: 0.01
but it is not working
same as cycle_time: 0.01
i can put the slider on 50% it works fine
watch with audio
Its not an uncommon issue, i thought it was inverting the pin that'd fix it. Search this discord and I'm sure you'll find an answer
That's the main MCU fan pin, but you have it connected to the tool board
So you have to reference the tool board pin name
Something like
!toolboard:fan_part_cooling_pin
pin: toolboard_t0:PA0
thats what i did
And it worked?
no
Try with the
!
like in my example, that's what inverts ityes the ! did it thanks al lot
