Probing on the 4th is basically the same as probing on Y(flat Plane) the difference is the Point values are angular not Cartesian.

So you may have to convert the values back to cartesian for the program that deals in points clouds to be able to use them.

Then when you are ready to POST the gcode it has to be converted BACK to angular values for the A axis to use.

I am assuming that you want to probe engraving on a post or something similar?

Just a thought, (;-) TP

How would I convert from angular to Cartesian?

Just a thought but it IS possible to trick MACh3 into using the A axis as Y so you could do the process directly as a standard XYZ plane instead of angular thrown in the mix.

You could also engrave on the A axis the same way. Mach3 will think that  A is Y.  There is a subject here on the site that deals in it

TP you have given me food for thought.

All I really want to do is take it we ms that I turn on my wood lathe, probe them on my rotary axis, then design something that can be cut on the surface.  As Gerry mentioned I can use a single line of points for this, once I figure out how.

It would be nice if there was a program that could convert raw data points from angular to Cartesian and/or vise versa.

OH there probably is (;-) Somewhere. I'll take a look. Most cams can take Cart (XY)and convert to Angular(XA) on posting. It is a wrapping feature.

Yes Gerry HAS the right approach(;-) BUT that just gives you a LATHE solution for the profile.  IF you are wanting to carve a design into the profile it is another matter.

Just a thought, (;-) TP
