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:

Aluminium profiles 20x20mm 600mm long2https://amzn.to/4azt8Xohttps://bit.ly/3TUNDp4https://bit.ly/2O1HR53You will most likely buy longer pieces of aluminium profiles, rods and lead screws and cut them to a proper length, if you want to build, bigger machine you just have to change lengths of those items, everything else stay the same

It may depend on your construction I used 12 of these, it's fast to print so you can always print more quickly
