gt2560 pins

[jorksx]

Hello.
Does this geeetech gt2560 board have any unused pins that I can control 12v ledstrip?
Right now I just activated extruder 2 and soldered led strip to it and it works. But I would like to script it to change colour with temperature.
I've looked through the pins.h file and nomatter what I change or try, the pins dosent seem to change. example I tried chaning extuder 1 pins to extruder 2 pins and 2-1 and still, the extruder 1 had old pins. From pins.h I changed the pins where it was "board ultimaker"

Another question can I use drv8825 stepper driver with this board and what do I have to change?
