Hey guys,

So I am order all my parts in the next week here to convert my Harbor Freight mill to CNC. I found lots of different breakout boards. This seams to be the most popular-> CNC Router 5 Axis Breakout Board for Microstep Controller 0 10V Analog Output | eBay
But my eye caught this one-> Upgraded 5 Axis CNC Breakout Board for Microstep Controller Cables Software | eBay

So my main worry is getting a breakout board with out the driver for the USB. so since this comes with a CD it makes me feel a bit better. Now I see most have a DB 25 with USB, Can you choose what you wanna use? Or do you have to use the DB25? If so whats the USB for?


Thanks!
