I wonder - I got a Sieg KX1-NU CNC mill, without controller. It had two boards in it; one was a specific speed controller board, the other was, from my understanding, a common Sieg board.
Go to littlemachineshop.com and look at the replacement parts for their smaller CNC mill. (look for replacement parts, CNC machines, 3993 control board, 3501 spindle; it plugs into the "motor controller, 3501 spindle" board) Ok - the little board had on the screw terminal connections: - isolated power supply; - 110v input; - isolated 5v output; - analog speed in; - ground; - direction; - something else. It was really, really easy to send the +5v, ground, and analog in lines to the Gecko G540 that I put in. I did have to adjust the on-board potentiometer on this little board to give me maximum speed with +5v; as it was probably set up for 0-10v. I wonder if this board would fit in your machine? A bit expensive, but a plug-n-play solution, if your "motor controller board is the same.
