I have done some PCB routing. I am using a Sherline mill for the hardware and Eagle PCB (www.cadsoftusa.com) layout for the design. Eagle has a user language program (ulp) that generates good G code. Some comments: 1. Very fine line routing will be disappointing, it tends to push the coper out of the way rather than cut. This is in part due to the low spindle speeds. The velocity of a 1/32 or smaller mill at the cutting surface is quite low. A high speed spindle will help immensely. For wider lines the resolution is good enough and it is quick. 2. The best method, at least for me, is to use a toner transfer technology to produce an etched circuit and use the CNC mill to drill the holes and cut out the board. This process has a number of limitations but gives me decent boards fairly quickly. Hope this helps, Frank ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
