Milling with Genmitsu 3018 Tips that may be helpful

  • A good distance from the spindle to the milling bits would ideally be (15mm). Beyond 15mm the trace would be too deep; less than 15mm, the mill will not cut through

  • Airpass. Airpass is very important, it would reduce the chance of failure

  • Heightmap. I learn that a PCB board is not always flat. Heightmap will help to make the machine adjust to the PCB - especially if you’re using a jig rather than a sacrificial board
  • The more you mill, the more you cause wear and stress on the milling bit. This can affect your milling results. In the context of tracing, after several mill jobs - you can start offsetting the height so that your trace tracks will come out cleanly.
