Hello All,

Been doing PCB's for years, though usually using the tried and true laserjet and deadly acids method

Anyways, I have a mill, and wanted to start playing around with PCB milling but have a few questions.

First, I have aspire and mach3 on the mill. I was wondering what I do with the files that pcb-gcode seems to generate. Do I try to dump them directly into mach3, or run them through aspire first?

Second, alignment. Most of my projects are two sided boards, so I was wondering what techniquies you guys use in order to align the other side of the board. I know with wood, I would usually drill some holes in all four corners, evenly spaced, and use them as guides when I flip the workpeice.

Thanks
