Gcode I think

[Mr.Chips]

My machine is almost done and I was wondering if someone would write three routines for me.

I want to run each one seperately. This will let me know how accurate it is.

1. Cut a square, 10" on each side and 1/8" deep.

2. Cut a circle with a 4" radius and 1/8" deep.

3. Drill four holes 1/4" dia and 1/8" deep 20" apart. Drill at the corner intersections of a 20" square.

Tool will be 1/4" in diameter.

Skiping a bit of other stuff that may be needed...
Be aware that different controls may require differences in the G-code.

X Y zero is the center of everything. Z zero is the top surface.
no cutter comp or spring passes. Just one pass at the desired finish size.
Putting in feed of 10.0 Change based on your spindle speed and material to cut.

Please check this on your control and make sure it runs as expected before putting a tool close to the part. While this would work on the controls I have, there are several unknowns about how your control expects g-code to be.

Thanks Dale,

That's exactly what I was looking for.
