Grounding upgrades to the Melzi board out of a Wanhao duplicator / Monoprice select 3d printer
Early revisions of this board have issues with inconsistent extruder / hotend temperatures. This mod is

Found what seemed to be a fairly decently made book light / work light at a local hardware store. Turns out it will overheat and melt the top over time. The original light lasted a half hour when used non-stop. The one tested in this video only lasted a few minutes.
