Just answered your ticket.
The Carbide Motion board is available on an as-needed basis. Issues are:

- power supply connector — some folks have just wired power in w/ a soldering iron
- heat sink and enclosure
There some other options listed at: https://wiki.shapeoko.com/index.php/Advanced_Electronics and Discussion of alternative controllers and I will specifically note:
