IF-THEN Statements in G-code

[Kirk Emmons]

Can a person put an IF-THEN statements in a program.

This for a HAAS 3-Axis Vert. Mill.

For example, this is what I want to do.

Run part of a program

M00

Wait for operator input (a "Y" for yes or a "N" for No)

If the op type y, the program continues on to the end

but if the op types "N" then the program goes back to rerun a certain tool.

Is that scenario easy to do & how do I do it

[Thad]

No problem on our Fadals. You may have to pay extra on a Haas for Macro programming.

What does the syntax look like.

We have three FADALs also.

Something along the lines of...

I haven't done any of this stuff since the late 90s, so I might be a little off. Check the macro section of the Fadal manual for more examples.
