Lights for 3D Printer

2021-04-14 21:44 - Making

I've wanted extra lighting on my 3D printer for a while, but only a little. A while back I replaced the broken extruder(s). The old ones had fans built in, but they always seemed pointless: they were mounted on the outside of the extruder, so they couldn't even cool the stepper effectively. And they were incompatible with the new extruders so they came off.

LED light strips installed on the bottom of the top layer of my 3D printer.

This left extra unused power connectors exactly where I planned on installing lights. Today I finally took the time to put some LEDs from the strip I already had in place, using that connector. They provide decent illumination, but reveal how unreliable the 12v rail is: I can now see as the heaters kick in, because they cause an immediate dip in the brightness of these LEDs. I'll need to try adding capacitor(s), at least.
