Why can't you measure the original?

With the sizes of the part, a program of approx 20 lines of nc code would make that part.

Without the true measurements its a guessing job, and a picture of 150*150 pixels is useless.

G20 is Inch measurements

G21 is Metric measurements

G40 cancels all old offsets

G00 is move in rapid

G90 movements are absolute

G80 cancel all drilling/tapping cycles

G91.1 use incremental arcs in G02/G03 (must be on a line of its own)

G90.1 use absolute arcs (must be on a line on its own)

Looking at your last program I would suggest :-

G20 G40 G00 G80 G90
G9g.1

Note

G9g.1  G90.1 or G91.1 depending on what your CAD/Cam system puts out for IJ's on G02/3

I think its the G80 that kills all modal commands, I asked Art about changing this some time back, so everything went back to how it was before the cycle call, but it sounded is if that may be a major job.  Maybe in Quantum.

Finally got hold of Ed, he gave me new email addresses that work.

Job sorted, thanks,

If you draw a rectangular box the length of the circumference of your ring/counter in the y axis and fit your text into it.

Then configure your A axis so that it is linear, work the steps out for 1" or 1mm of arc at the circumference of the ring.

Post out the code and change all the Y axis moves to A.

Run the program at your own risk.

Or

Use a CAM system.
