3D Printing Forum

Someone here that knows if any of the UN-used plugs on the plugboard (behind where the ribbon cable is connected to tha gantry) can be used for switching 4 LEDs ON/OFF from a switch I mount beside be screen ?

I assume there is some power to get inside (only <=100 mA) it could be nicer instead of having two extra wires running along the ribbon cable.

None knows anything at all ?

Now I got 4 white LEDs mounted in a printed bracket around the nozzle, driven by a constant current sink 20mA and cable along the filament hose to an external power suply - it works nicely !

Now I just need to find a method to get the cable from the gantry to the base box and there find a power source.
