Y-axis Reprap redesign with integrated PCB Heatedbed.

The Prusajr’s PCB heatedbed is a very interesting commercial piece for its simplicity and performance. The problem is that it doesn't fit perfectly with the design of the Y-Axis of Reprap.

Due to heat, expansion, and fixation at the four corners, the platform could reach warp. To fix this I have set the platform under an 3 mm aluminum plate to provide rigidity and protection. The platform is placed upside down, where hotter. The protection of the upside PCB is replaced by the aluminum sheet
