I like to install a fan for Filament cooling. My Printer has a GT2560 Rev B board. Unfortunately there is no circuit diagram for this board available. There is a connector on the printhead board available for an additional fan. But I´m not able to find out how to use it. There are some informations in this Forum, but they don´t answer my questions.
Can you please send me a circuit diagram for the board? Or can you tell me how to use the additional connector for the Filament cooling fan?
best regards
Peter

Hi Peter,
to connect an additional fan to the printhead board you need an 3-pin JST-PH connector. If you have plugged the connector in the board the pin on the top is + (red) and the middle pin is - (black).
After I updated the firmware to the latest version the fan is working without a problem.
You can find the firmware here: http://www.geeetech.com/forum/viewtopic.php?t=17046
I hope this helps.
