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
