Makerfarm i3 8" Prusa Printer Tweaks

Certainly you can power them directly from a power supply. You might want to add a switch to turn them off since the circuit is outside of the printer control board and GCode switching. I'm bummed now because I took my power supply and trimmed off all of the extraneous wires and left only the ones that feed my controller. I then taped and used head shrink on the nub of trimmed wires. Now I'll have to undo all of that to tease out a pair of 12V leads. Some light in there will be nice as I'm always in there there with my small LED flashlight.

I am going to wire in where my 12V supply wires into the RAMPS board on the bottom left hand corner of this diagram. I am not going to bother with an an/off switch. The LADs can stay on all the time that the printer is powered up.

That makes sense. They draw such low power and put out little heat. Plus, the lifespan is so long who cares, right? If you rim the rest of the frame in blue it will look very "Tron."
