This is my first CNC machine build that I like to use for PCB milling. I decided to use the C-Beam Machine Plate Maker as starting point. I build the machine using the build video during the x-mas holidays. The build is not finished yet but everything is operational. The first thing I like to add is a panic button. In the future I like to buy a DeWALT router for more demanding work. For now I think the Dremel 4000 wil work for PCB milling. I 3D printed an insert for the standard router mount to fit the Dremel. I designed and 3D printed a housing for the xPro and the end caps currently in blue. For PCB milling the bed levelling is essential. I saw that other builders use a mill to flatten the waste board. Is this the best way? Does anybody have experience with this?
