I have the following code that I'm running as a test just to see if everything moves the way it's supposed to.    I'm getting the following error...

R ijk words all missing for arcline 15.

The program stops on line 15 and generates this error.  I'm not sure what this means considering that this line is a Z retract move, not an arc in the XY plane.  Has anyone seen this error before?  Other than this error, the machine runs the program as it should.

Thanks...

G3 is modal - stays in effect until changed.

Put a G00 or G01 in front of the Z move

Thanks very much...That's what I get for messing with too much at one time.  I was playing with some posts and that got changed.
