PCB heated bed. I'm working on this idea for nearly six months, inspired by neufeld.newton.ks.us/electronics/?p=864 .

Sides

PCB Bed has two sides, one with the traces (bottom side) and one with silkscreen (top).

Printing on top side is safer, works great.

Printing on bottom is more effective and heats up quicker.

Connection

Polarity doesnt affect anything.

Leds

There is place for two leds you should put each of them in different direction so atleast one of them is lighten up, no matter what polarity you use.

RAMPS

Its now in working state, Printed load of kits on it, working great. PCB HEATBED DIAGRAM.jpg PCB HEATBED.jpg


Main Idea is to use resistance of pcb traces as heating element.
