This is the build of a cartesian 3d printer made of an old Anet and Geeeteck, some 2020 alu profil and linear rail. Powered by a Rumba with a Nextion screen. It should be modular and accept dual Extrusion and laser engraving.

Cartesian style CNC with a working area of around 360mm x 360mm x 120 mm (X, Y, Z) using Linear rails and ball screws. The linear rails are (Hiwin?) HGR 20mm x 520mm and the ball screws are SFU1204 (12mm lead 4mm) of around +/- 430 mm. The base structure is made from rectangular aluminum profiles of 70mm x 45mm x 3mm (thickness of walls).

I decided to start designing this printer, this will be my solution for a more rugged printer that you can use as workhorses...

It's a Z floating head idea. Works well. Recommend cleaning the inside of your holes well with Q tips, and polishing the 1/4-20 bolts with car wax and you won't need oil as it slides perfectly. Hope this helps

That is the only cnc you will need for most of your diy projects.
