Hi all,
I build my CNC, to do PCB, i started from an old project and I add some addiction and I create the electronic with limit switch probe etc..

Here my tutorial to build 3D printed CNC
https://www.mischianti.org/category/tutorial/cyclone-pcb-factory-how-to-build-it/

And Here the FlatCAM tutorial
https://www.mischianti.org/category/tutorial/flatcam-complete-tutorial/

But my first CNC is in my heart :laughing: It's working, and I create a lot of PCB with that...

Naturally It's for home use, but I resolved a lot of situation with that.
