Summary

Everything below this point is working notes. This board is a work in progresss. It is currently working as shown built on an Arduino manufactured Arduino MEGA Shield, but we plan on printing it on Mendel with the marker or plastic printed on copper etch resists methods suggested by Vik. This board is mostly a copy from Adrian's Pololu_Electronics. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. It has provisions for the cartesian robot and two extruders and a heated bed. It fits five Pololu A4983 stepper drivers and all needed mosfets and thermistor circuits.

It is designed to be printable on a Mendel :)

This is the front of the shield.

To Do:

The wiring for the back of the shield is quite tedious and error prone. Modifications to Arduino Mega may not be preferred for everybody.The voltage regulator on the Mega board does not like voltages higher than 12v, my power supply's voltage of 12.6v gets it pretty hot
