G-Code, CAD, and CAM discussions / Radius to end of arc differs

« on: November 22, 2007, 04:48:19 AM »

I can run the contour section by itself with no problems. But when I try to run both parts or just the 3/8 hole part, I get the radius error. I don't understand what the error is or why I'm getting it and especially how to fix it. I could write the program so that it will work but I'm trying to use the L word to shorten the program to under 100 lines or so.

Oh that L19 is exactly what I've been needing. I'll have to do a little studying to fully comprehend the G91 and G90 thing but I think I have the basic idea. Using L19 could really shorten some programs, couldn't it?
Thanks, gs

I'm not sure why this code is skipping depth passes after the stops at the beginning. I'm trying to run the same contour code over and over and incrementing the depth by 0.02" each pass. For whatever reason, it goes from -0.02, to 0.06 to 0.10, to 0.14. It's skipping 4, 8, 12 etc. Did I do something wrong or is this a limitation of the demo?

How exactly does the Run From Here button work in ToolPath view? I've tried it a couple of times but couldn't get the results I was expecting.

I have a digital caliper that opens to about 12" or so. That should work in place of the dial shouldn't it?
