Hi Gene Why not up to speed with Eagle, albeit a horrible package. This has all been done !
The free version of eagle should suffice. There is an automatic g-code generator. Thats the best part. And some guys have written apps to probe the board prior to milling, to correct for undulations. If you look through the archives on the Yahoo forum, you should find all the info you need. See www.pcbgcode.com Regards Roland On 11 January 2012 07:53, gene heskett <ghesk...@wdtv.com> wrote: > Hello all; > > In carving these pcb's for the encoder, I only have room to clamp one edge, > the back edge of the pcb. > > I carved a dead flat pocket about 30 thou deep and slightly larger than the > raw pcb material, gouging out the left front corner so the board, when > pulled left & forward, isn't riding the corner, but is located by the left > & front edges of this plywood containing the milled pocket.
