This 3-axis CNC milling machine is proficient in working with circuit boards and soft metals like aluminum. The machine's software, compatible with dxf and gerber files, utilizes Planet-CNC controller to generate g-code. Manual operation is possible with the jog pendant, which displays digital readouts of axis positions on the PC interface. The innovative design employs aluminum extrusions as slides for the mill, requiring adjustments in printer settings for optimal slide fitting. The exploded diagram and bill of materials serve as a guide to assembly. Hardware such as screws are not included, necessitating individual procurement. Despite limited testing, the machine demonstrates precision and accuracy. A tool makers vise is used for aluminum milling, enhancing cutting smoothness. This design may inspire further innovations among users. Inventor files are provided in a dedicated folder for easy access.
