What do you not like about the G code?
I do see that the Z commands are all z0
I don't know MCX very well, but I'll try to help.

Your code does not look good. Going to Z0 first, then a rapid in the X-Y plane looks dangerous.

There should be considerable initialization before your first line of code. Mastercam post is a problem or you have not supplied Mastercam enough information.I would expect a % at the beginning followed by an O-number, and at the end M30 and the ending %.

I didn't see anything other than an extra "G00"?

That looks like a bunch of extra code, what type of cnc machine are you running?

The code shows an "A-axis", are you just running a 3-axis mill (XYZ)?

[frankg521]
