Thanks for the kind words. The source code is available here: https://github.com/sshwarts/2.xLaser/
As are all the STL files for the parts I 3D printed.
I used NEMA 17 steppers. 200 step/rev.
I used three of these drivers: http://www.lightobject.com/Mini-2-Phase ... -P650.aspx
I bought a 24V DC 14.6A 350W Regulated Switching Power Supply on eBay: http://www.ebay.com/itm/24V-DC-14-6A-35 ... 3cd0b1c717
The daughter board I built has a buck converter on it to take the 24V down to 9V for the Arduino. It also has a 5V regulator to power the red dot laser target and the relay boards: http://www.amazon.com/gp/product/B00E0NTPP4/
I used 22/4 Stranded shielded to go from the Steppers to the drivers and from drivers to AWC-608. For all the internal wiring (not counting 120V), I used 22 AWG. It all runs in sleeves (Techflex 1/8" Expandable Sleeving). Wiring from limit switches was twisted pair (salvaged from ethernet cables).
Ask away any questions!
