This Project is close to realized and has renamed to XStepper. If you need actual informations, please visit this links:
i want to create a box with some Arcarde Buttons for feed Hold and so on ...
My Problem is, i have only the Buildlog Stepper Shield. It is difficult to connect the wires at the right place. In this moment i decide, maybe it's better to design a new Stepper board with all connects for spindle on/off, buttons and endstops.
Here is my first draft, the most elements are stealed from RepRap project. They use a Atmel mega ... in this example i use a normal 328:

He use also a FTDI Chip for USB Connect ... this schema is close the same as Arduino + StepperShield + EndStop terminals + Spindle Terminal (Solid State Relais is planned)
First some points:
* It's only a draft, maybe you or you see some mistakes ... please let me know where
* at this time, i create only a schema in eagle, feel free to make a board with this data
