This page describes my capabilities and lessons learned with CNC machining. My first CNC machine is the MyDIYCNC machine, found here: and was built from the complete kit. The machine was upgraded with a more powerful spindle (300W DC), and corresponding stronger Z axis sled. The X-axis base was modified to increase travel range to 11.6", with a final total X/Y range of 11.6 x 4.2". I have since purchased a Harbor Freight Mill (#44991), aka Sieg X2 clone, which should be capable of machining aluminum. This page will also serve as a cost breakdown of all components needed for the complete systems.
