Ok still some way to go yet before it's working, as has been mentioned controlling the extra axis could be a little tricky, would be cool if someone figures out how to use a brushless gimbal board with Ramps or other controller.
Of course I need a rotating unit for the 4th axis, and need to rotate the Y axis 90 degrees, but I'm waiting on a few parts before I can complete the Y and second Z axis
