Talk:Mendel LED print light
I had been thinking of hooking up a LED under the X-axis carriage; this could either be powered in parallel with the heating element (meaning it would switch on and off with the hot-end heater), or preferably, would have its own wires back to the power supply so it is always on. I hadn’t got around to working out what specification of LED(s) I should install, when I came across a cheap USB LED-Illuminated Magnifier in a “Specials” bin at the local supermarket – only $4 for a really bright lamp with 18 LEDs in a ring, and a nice flexible “gooseneck” for positioning. I have attached this to my Prusa Mendel, and it draws power from the 12 V supply to my RAMPS (using a 100 ohm resistor to limit current / voltage on the lamp module).
