Delta Fan not turning off at 0%.
I have installed a delta fan today, and the fan will not shut off when its indicating 0% in the dashboard. I have everything connected to the octopus 1.1 pro board like in the screenshot attached. I also included the following to printer.cfg:
[fan]
pin: !fan_part_cooling_pin
cycle_time: 0.01
enable_pin: PA3 #I checked the pin diagram for the heater controller pin HE1
Would anybody know what I'm doing wrong?

Now I've tried wired as in the attached screenshot, and replaced the fan override in printer.cfg with the following:
[fan]
pin: !fan_part_cooling_pin
Same result but the fan is at a higher RPM whilst stating that it's at 0 procent in the dashboard. I'm a little bit lost thb
If you move the slider to 100% does it speed up?
I can't move it to the right. It's the part cooling fan of which I don't have a tacho installed.
don't need a tach pin to control speed, you control it via pwm pin. Like in your drawing
I'm going to recrimp the pmd wire. It behaves the exact same while it's pluggin in or out
Alright.. After recrimping the pwd wire I accidentally connected it to the 12v pin of the board so I think I fried the fan
woops
Board can't be fried by that can it?
Everything is working on the board just not the fan
If the board is working, then the board is working 😄
I'm closing this thread until I get a new 4028 unless anybody has an idea what my original mistake was.
