Hi!
I am interested in your project. I can start as soon as necessary.
In my portfolio I have photos of a CNC that I built, I designed the structure, the spindle mechanisms, and the pcb board.
The firmware I use is a free one that gives me excellent results. I need more details, for example, the type and size of the motors you want to use.
Anyway, I'm sure I can help you.
Greetings!!
