Total newbie to CNC. In fact I don't even own a machine yet. I am considering buying one of those cheap CNC 3020 routers on eBay. Mainlly to etch PCBs. I figure it will make a really cool toy.
I saw some articles on etching PCBs. A really important step is to get the PCB really flat. One trick to do this is to super glue the PCB to an aluminum plate (a little acetone and the PCB is free). But would this make drilling an issue? I think the people that do this, work with surface mount parts which require no drilling.
Is it possible to do this operation in two steps using Mach3? Is there any way to set a "home position" so the routing job matches up to the drilling job?
I would imagine there would be similar issues with double sided boards.
