RE: [CAD_CAM_EDM_DRO] 20 questions - long

Hi,

For a small 3-axis stepper controller you cannot go past
http://www.xylotex.com/

If you need a breakout board have a look at: http://www.campbelldesigns.com/
They have other parts that may be of use to you.

For a PCB spindle have a look at:
http://www.angelfire.com/az2/proff/PaulJonesPCBSpindle.html Paul also has
other parts that may be useful to you.

Cheers,


Peter Homann
