L297/L298

I finally finished my Fireball V90 CNC build.  In May, I got the frame, and I planned to use the motors and electronics I purchased for upgrading the Valkyrie-clone CNC.  So I made some NEMA-17 to NEMA-23 adapter plates from CD-R disks, and got it all up and running.  It's running off 12V for now, with 24V planned in the future.

In the picture from top-left, clockwise to bottom-left: the terminal block (24V power up to 13A), the 2 X-axis drivers, the Y-axis driver (blue heat sink), and the Z-axis driver (blue heat sink), the Arduino controller (direction x3/enable x3/step x3), and just below the terminal block there is a small 9V regulator board to shift 24V down to 9V for the Arduino.  Everything is mounted on an MDF board, and the board is mounted with baling wire.
