No Output on Fan0 for Part Cooling #18298

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.

I have included a copy of the Config.h and Config_adv.h files as well as the Pin file. The fan won't turn on with the m106 s255 command, or won't turn on during printing when called for by the slicer program Archive.zip

@quad121 still an issue?

quad121 commented 4 years ago

Under further investigation, the fault lied with the MOSFET which supplied Fan0 not the Marlin firmware. So apologies, I will close this ‘request’ error.
