What ? My biggest project. It's a 1000x500x80mm CNC router.
Why ? Different tools can be set on the machine (laser, spindle, plasma torch, cutter etc.) and so it offers a quantity of possibilities for anything fabrication!
How ? I'm currently building the mechanical function. I use standard BOSCH 30x60mm Aluminium profiles for the structure. Axis motions are made through ballbearing screws. I designed brackets for NEMA23 stepper motors and 3D printed them. As soon as machine is operational, first machining shall be these pieces, easy to print still strong, but with expected short life duration. I am constantly updating design along the building.
Recommend a perfect axis drive stepper motor and driver.
