Facing Macro

I use this a lot for quick stuff. Thought it might be useful to someone.

V1.1

Been a while since I had to think through a programming problem and I ****ed up the loops so it went to the wrong position without the reverse direction of last pass flag set.

Probably going to set it up to use SFM and FPT rather than RPM and FR later.

Nice Job!!! I barely know what I'm doing when it comes to custom Macros, but I really wanna learn more!

Might try that out next week when I get a chance.

Thanks for sharing

If you're using a Haas there is a programming reference in the back of their book.

The standard that Fanuc based controls are using I think is RS274D but there is also RS274-NGC and ISO 6983.
