Thank you for accepting me into your forum.
I have recently fitted a BTT SKR 1.4 Turbo motherboard to my printer.
I’ve got everything working except for the Part Cooling fan which doesn’t turn when needed.
I’m using Marlin 2.0. Bugfix version.
I have my hot end fan connected to the HE1 connection (pin 2_4) . Which is defined in Config.h as; E0_Auto_Fan_PIN P2_04 , which switches on at 40 degrees.
The fan for the Part Cooling is connected to Fan0 (pin 2_3). I only found reference to this in the ‘pins_BTT_SKR_common.h which is under the heading Heaters/Fans.
I checked the cabling etc and tested the fan0 skt but it was only putting out around 3v even when setting the screen settings to full or off.
I have attached the pin file, if someone could see if there is an error which would be stopping the fan from working I would be very gracious.
