I've already cut a piece which has two holes that I would like to move to another location on the same piece. Naturally, I no longer have the x-y coordinates on the machine. Is there a procedure that would allow me to precisely place and drill new holes on the piece? I was thinking of using the two existing holes on my piece and use this as a datum points for establishing new xy coordinates on mach3, but this requires a lot of trial and error, I think.

SO you wanted to be a machinist huh. Doing a reset is part of the gig.
Remount your piece then touch off to the inside of the hole then set an XY value to that point NOW you have a datum point to position your new holes based on the OLD hole.

I know it's perhaps going off on bit of a tangent but you may find this thread of interest, particularly as I am using two holes to reference the job. http://www.machsupport.com/forum/index.php/topic,22932.0.html

That works well WHEN you know the radial offset of the original holes from true. Otherwise you have to add/subtract the reference angle from the G68 offset.
