mbed 3D printer PCB
thingiverse
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...

There is only one jumper wire (on the top layer). Adjust the firmware to your printer and have fun printing :)
