I am a novice to the CNC Router game but I am going to attempt to build one of these wonderful machines. My question is ... From what I have read, some people make plotters, small CNC machines from old printers. I have several old printers around the house. Can I use one of these printers as the drive board for stepper motors? Or am I missing something here. Why do I need to purchase a driver board? Couldn't I use the printers board instead?

It's tempting but don't bother. Printer motors are specialized for what they do and what they do is not CNC. Go to www.usdigital.com and for $50 bucks pick up the motor they are selling. Go to Camtronix and pick up on some of the fine motors they have. You will spend the same or more on a drive, be it Xylotex or someone else's.

Have the motor be what's needed. Pick one about 3 to 4 amps per phase. Use a 36VDC to 48VDC supply. Then you will get the mechanical power needed to move your load.
