From CAD to Product using the blackTooth Laser Cutter
Here is the complete process (overview) on how to create create a box with using the box joint (finger joint) method. The overview will explain the process of drawing the sides of the box in CAD, applying the machining operations in CAM and finally cutting the parts with the blackTooth laser cutter and engraver.

How to Determine the Focal Length Measured from the Tip of the Nozzle.
Here, I describe one technique to determine the proper level of the nozzle so you can get the optimum focal length form the tip of the nozzle, not from the lens within the assembly. Trying to determine the length from the lens to the surface to be lased is very difficult because the lens is hidden within the assembly of the nozzle. This technique will allow you to determine this distance from the tip of the nozzle to the working surface.

Katy Makerspace blackToe Build Part 1
We're proud to be affiliated with the Katy Makerspace. We recently provided them with a blackToe for their members to use. In this first part we'll be examining how they went about organizing parts for the initial build, as well as constructing the table.
