I noticed that the G-Code posted by VisualMill 5 is in metric even though I have units set to inch. Is there something I am missing here ? Maybe another setup for post options ?

Thanks

I figured out that VM has a post code generator and with that you can look at the post type you are using (in my case Mach3). I saw that the units setting was for metric rather than inch. I change it to inch and hit save, Now when I do a post it comes out in inches rather than metric.

Hi. First post here.

I just solved this, I hope, this way:
- From the top menu, go to Post Process / Post Process Generator
- Select your post processor from the list.
- Select "Edit" (Mach3 in my case)
- In the "General" tab, under "Units" make sure "Inch" is selected.
- Here's the tricky one, under the "Start/End" tab, look at "Program Start Up Code". This will be the code "block" at the beginning of your G-code. There probably is a "G21" entry. That tells your controller to use the metric system. Sneaky, huh? Chage the "G21" to "G20"
- Save the whole thing, or, if so inclined, Save As.. with a name like "whatever INCHES.whatever"
- Use this new post processor next time.

Hopefully that does the trick.
