Re: [CAD_CAM_EDM_DRO] Re: CNC: Spindle speed control

Hi guys;

If you have the proper files for making the circuit boards, you can have them
made by one of the many companies that provide just that service. Some of them
aren't all that expensive for one-offs. I can probably dig up a few URLs if you
need them, but you should be able get quicker results with a web search.
