About this 3D model

This PCB connects an mbed microcontroller board [1] to a Sparkfun Quadstepper Motor Driver Board [2].I use it for my RepRap Prusa Mendel 3D printer but you can use it for any CNC machine.The firmware [3] for the mbed board is based on the Tonokip firmware and is compatible to ReplicatorG using the fived driver. There are jumpers for a 100k thermistor, a hot-end (via 3.3V mosfet) and a thumb-joystick.Update: new version (mbedquadstepperminimalNOatmega8u2.brd) has 2 mosfets and 2 thermistors and 3 min-endstops pins... but no support for atmega8u2 or thumb joystick anymore...[1] http://www.mbed.org[2] http://www.sparkfun.com/products/10507[3] https://github.com/renebohne/RepRap-Firmware-for-mbed-microcontroller
