The breakout board in the photo (reply #14) is a 5-axis CNC breakout board sold by StepperOnline. You can download the PDF manual from that site. The manual has the complete "Ports and Pins" settings, pin #'s, setting the Spindle 0-10v , Limit/Home switch setting pin #'s, and a very good pictorial schematic of all the connections.
It will work with a parallel port cable, or the UC100 USB / Parallel device.
I have assembled a 3-axis router package for a client, using the UC300 board (the big brother to the UC100), and followed the PDF manual. Everything works as described. There are some very specific Ports and Pin connections to get it all working correctly, so following the manual is advised.
You will need a 12 or 24 volt source for the 0-10v output for an inverter. It is a very compact, and simple board that works.
