4028 Fan inverted control
Hi all I have got a question, I have V-Core 3.1 and I have connected 4028 Fan, +12V is from stepdown, GNf pole is on heater 1 as enable pin and PWM is in toolboard EBB42 v1.2 PA0. But the Fan runs the oposite way if I send M106 S1 it runs at 100% and as I am going higher M106 S5 - 255 the fan slows down how can Iinvert the logic? Exclamation mark in front of fan pin makes no diference. Thank you

pin: !toolboard:PA0
cycle_time: 0.01
enable_pin: PA3

post your printer.cfg please
The Fan settings are in the original post. The rest is standart.
Order matters, so we really do need the whole file not just a snippet
Understand, I will send config tomorrow, at the moment I am out.
This is the actual config file. Thanks for any hints
And as I mentioned in original post, I have removed the exclamation mark and it did not help.

You didn't put the overrides in the correct spot - lines 159-162 should be in the USER OVERRIDES section

RatOS uses a modular configuration that heavily takes advantage of the config file include and merge logic in Klipper. For this reason, the order of includes and overrides are very important, do not change the order of the configuration unless you know what you're doing.
Great thank you, you were right. I did put it there, but on the wrong place so it did not make difference, now it works. Cheers. 🙂
