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.

CNC Halftoning Tutorial
In my usual morning reading, I came across a post at Evil Mad Scientist Labs showing off CNC halftones using ASCII art. I was compelled by one link in this post showing a very creative alternative to the usual halftoning done by a CNC machine. The link provides the steps to achieve this effect using your CNC machine.

Step 7: Z-Axis Transmission Nut
This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. Instead of using allthread for the lead screw and a standard nut, consider using a 5 start lead screw and anti-backlash nut. It will keep you from pulling out your hair by running much smoother and faster. We will install the method that provides transmission to the z-axis. The transmission consists of a lead screw and a nut. Very simply, the motor will turn the screw, and the nut is fastened to the z-axis assembly, moving the assembly as the motor spins. That is to say, when the motor turns clockwise, the nut will travel up, and if the motor turns counter-clockwise, the nut will travel down.
