Any G-Code CNC Experts?
 

I have little work project that involves turning camera X-Y data points into a 2-D CNC program in G-code.

I don't know too much about G-code, so:

What instructions make the path inside vs outside the shape?

What is the origin as reference, is this set on the machine?

How do you indicate the cutter size? Can you modify the cutter size from actual to create an offset? i.e. to cut slightly larger or smaller?

I have some rough code I was given, if that's a good starting point let me know and I will post some of it.

Hmmm...where to start!

Ok, here are answers in order:

G41 (Left) G42 (Right) tell the machine what cutter comp to use. Instead of thinking of left or right, think climb vs conventional milling.

Your 'orgin' is set on the machine during program load/setup.

When you load/setup your program, you will (generally) assign your tools, by size and Z (quill) offset.

Sure post the code. I'll have a look at it. Let me know if you have any other questions.
