Results

Roland MDX 20

PCB milling

 

For the next boards to be milled, we concluded:

 

  1. Tool diameter: 1/64”
  2. Cut Depth: 0.004 in.
  3. Offset number: to be defined by application.
  4. Offset stepover: 0.5
  5. Speed: 0.8 for milling (if we use a higher speed while using the 1/64” cutter, chances are that it will break).
  6. Origin: x=0, y=0
