MAS 863 - David Carr. My final project is a 3-axis CNC milling machine that costs less than $100 (currently $87) to build.
It can mill PCBs, wood, and even mild steel. These PCBs were milled using the machine. The traces are 10-15 mils. HolzMechanik.de. This compact CNC Router is suitable for all those who want to mill soft materials like wood or plastic.
Her smart and stable design (hence the name Solidis), allows it to build the machine from wood. Because wood is very easy to work. Anyone with a drill, a jigsaw and a router (or table saw) can build the machine. High quality components like Ball Screws (D=16 x 5 mm), Linear Motion Ball Slide Guides and Units (D=16 mm) and powerful Stepper Motors (180Ncm, 2.5A, 1.8°) are used.
