In my previous videos, I used this CNC 3018 Pro to make some aluminum 3D printer parts. As many of you are interested in how I upgraded this $149 CNC to cut aluminum, I am going to make a series of videos to show you everything including the hardware upgrade, firmware configuration, using Fusion 360 CAD for 3D modeling and using Fusion 360 CAM to generate G-code for the CNC. In this video, we will start with the most important part, upgrading the 500W spindle. You will see the detail process, what hardware and 3D printed models you need for this upgrade. I will also show some aluminum cutting footage so you can expect what you can get after the 500W spindle is installed.
