There is strong evidence to suggest that a shorter wavelength laser (450nm blue) has different ablative properties than 10,400 nm (CO2 - IR).

So, a 5 Watt blue laser was added to the short bed tool head.

The CO2 laser head is on the right, pointing up, the 450 nm laser on the left. The ink jet printer head in the center.

TheInkShield is at the bottom.

Of course in operation the assembly is rotated 180 degrees.

I hope the three days invested in this mod are not wasted!
