Parts needed. Power supply and USB board.

[ukracer]

When you say they are throw away do you mean its not possible to buy new boards and use the same power supply and then connect them to the motors in the CNC bed??

This for example?? (first one I found) http://www.ebay.co.uk/itm/3-Axis-DIY...item51c3886595

I realsie to make life easy I will need that

UC100 USB motion controller Will these not replace the motor controllers in my cheap chinese box? http://www.ebay.co.uk/itm/CNC-Router...item5d477c7b0c (if they are dead?? But if I need a new control board I am wondering if I should get this http://www.shop.cncdrive.com/index.php?productID=367 and 3 stepper drivers assuming my motors are OK and compatible. I am trying to learn which parts does what , as much as save money. I hope you understand :) Regards Andy T
