Bill:
>>My interest is in 3-D contour machining and was asking for
information not included in the manual regarding Mach2's specific
capability. G51 is the standard G code for it and an entry for
tolerance. Not included in Mach2...
Actually G51 is kinda standard for scaleing of axis, but then theres a lot
of standards. Sometimes called mirroring, but then thats simply a scale
of -1. Perhaps your speaking of finishing capability where you specify a
tolerance to stay away from the actual toolpath by a set amount??
I still don't get your point on faceting problems or excessivly long
programs. Though if your speaking of a finishing capability, then I can see
where the files would be longer by having the CAM program generate the final
passes, but then file length is not very important these days with multi-gig
hard drives everywhere. But how would lookahead have anything to do with
file length or contouring..
Forgive me if I'm being dense Bill, I just don't understand the question,
but "lack of lookahead" ius something I hadn't come across before, Mach2 has
more than any controller I've heard of in terms of CV.. I think I'm missing
something here...
