Cutting Aluminum with the greenBull CNC and Onsrud End Mill
In this video, we are showing 2 examples of cutting aluminum. The first example will be dry cutting which is cutting in the absence of a coolant or cutting fluid.

How To Have Two Motors on a Single Axis Spinning in Opposite Directions on a CNC Machine
In this tutorial we will demonstrate how to have two motors on a single axis spinning in opposite directions with the use of a hex inverter.

Step 8: X-Axis Front and Back
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. We are going to cheat and skip to the x-axis for a minute, well... actually 8 minutes since that's about how long the video is. The CNC router has a table, right? The flat piece that you put the stuff on to cut, right? Well, that piece has this thing called the gantry riding over it. How does that gantry move? It needs to hug this surface and requires a piece underneath. In other words, the gantry cannot move unless this surface is lifted above the ground to accommodate the gantry support and the motor underneath.
