Geeetech

No, but these fans are 12 V.

I need help to make them working, my PWM is working ( 2 pin ), now I have a extra fan who does not want to work, I tried in plug FAN 1,2 and 3.... nothing ! I have a Anet 8.

My printer is ANET A8, I changed the stock board for a GT2560, on your list I don't see ANET A8 (I know not from Geeetech), which one should I choose, I guess I will have to change some setting to fit ANET A8 specs.

Thanks, my PC has recognized the new port... but... in Arduinio 1.8.5, I did what Geeetech show on their web page... the firmware code doesn't show... I chose Arduino Mega 2560, no code at all to upload ????? Any help! Thanks.

I did a search over the internet... still no answer... any one knows where to get the driver, first of all I plugged the USB cable but my computer does not recognize it. HELP .. thanks !

Ok thanks for your help, much appreciated.

Thanks for your help Gingko!

Sorry I don't get it, are you saying, although my hot end and hotbed is powered directly from my ATX psu, still I need to connect 2 X 12V on the board? In the future, I will power my extra fan directly from my ATX psu.
