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. |
