Probe Problems

[IMSlo]

I tried to digitize a simple rc airplane body today. What should have taken 15 minutes took two hours.

I was running a diy probe. The procedure I use for digitizing is I jog to a point I want, probe it then jog to the next point. All I want is the x and y coordinates I am not usually interested in z.

Somewhere, maybe here, I got a digitizing program. It was an automatic program that would probe a grid.

I broke the program into three files. A program to open the probe file, a program to probe and a program to close the file. The procedure I use is open the file probe all the points I want then close the file.
,
Today I kept get a "probe tripped before G38 (of whatever the probe G code is) command executed" error. I finally got around the part after starting over many times and fiddling around with Z jogging. I even got my meter out and checked the the probe. It didn't look tripped but I thought it might have something in a contact that I couldn't see. The probe was not tripped.

My question: Is there a command that will save coordinates to a file without probing? I am always sitting on the point I want before I do the probe. If I could just save those points I wouldn't need the probe.

Thanks for the reply cncbasher.

Apparently there is a bug in the release I'm running. Maybe I can get an update before my next digitizing project. I only digitize occasionally.

I copied the code on the link supplied by cncbasher.

It works like a top.

All I need to do now is sharpen a 1/4" dowel, chuck it up in my router and start digitizing.

Thanks again for the reply.
