hello,
i have a dual extruder setup with a Ramps 1.4 Board and heating bed.
so i need a fan for every extruder so it switches on when heating is turned on and i need an aditional fan that is controled for cooling the print while printing (for bridges and cleaner prints)
i have a fan extension board
how can i attach all 3 fans so they will be controled when needed? each extruderfan and the printcoolingfan?
anyone done this already?
