I have been browsing through some of the information I find about CNC controllers using the Arduino, and I find a lot of useful information, but also some confusing information.
I have just started planning to make a CNC router, and I have got most of the parts, except the controller, which I will try to implement via Arduino Uno, if that is possible.
I have picke up some VEXTA PH265M-33-CS step motors for next to nothing in Chinatown Bangkok (I'm here for a vacation and will return home 16.th of July). This is a unipolar modell DC 24V 0,21A. I have read one place that high voltage give you a faster motor, and another place the low voltage give you a faster motor, so I don't know if I have made a bad choice (not a big problem - payed less than 30 $ for 4 motors).
Next thing I will need is schematics for a controller that can handle 24 volt, but I recon that will be on another forum.
