1 | Hey everyone! Excited to share my DIY DREMEL CNC machine project with you! Imagine a CNC machine that won't break the bank – built with a Dremel, LMU12 bearings, Nema17 motors, Arduino, and aluminum profiles, all under $350. I wanted to break free from the limitations of 3D printing, so I created a versatile CNC machine for wood, metal, and more. Follow my easy-to-understand guide, watch the videos, and grab the 3D printing files to assemble your machine hassle-free. You can find more information here: | |||||
