Different responses from two computers running the same gcode

[rexdc]

I am new to using mach3 and I have a problem in that I am using one computer (my laptop) to check gcode file and do testing on for scripts and the other to actually run my CNC router. one computer will read a gcode file differently than the other computer. The following code was load to the two computers.  This basically cuts a circle a little over 1 inch and .1 inch deep.  On my laptop this code runs properly but on the CNC router computer it somehow adds the     I-0.552 in line 5 to the diameter of the circle causing the end result to be an elongated x axis on the circle.  By changing line 5 to read G03 X0.552 Y0 I0 J0 F5 the cnc router will cut the circle properly.  Has anyone got a cue to what I am doing to cause this problem?
G00 X0 Y0 Z1 F5

G01 Z-0.1 F5
G03 X0.552 Y0 I-0.552 J0 F5
G00 Z1

Is the IJ (Gen. Config.) mode the same on both computers?

Thanks John that was the problem.   I had looked at the Gen Config file earlier but missed the IJ mode box.  I a greatful to you for the help!

It is a good idea to have the IJ mode set in the first line of your code, that way it will never be wrong for that particular code.

That sounds like and excellent idea, the omly problem here is that I am a newby, so help me with a clue with that line of code.

G90.1 is Abs IJK mode and G91.1 is Inc IJK mode.

Thanks so much for the help.  There are some nice guys in the world.  Sincerely, I do appreciate the help.  I am having some fun with this,  it marries two of I passions, computers and woodworking.  I've already tackles some screen mods for Mach3 and they actually work!  Been doing a lot of reading and some trials, not unlike some other programming I have done in the past, as i get a better understanding of mach3 and g-code this will be a lot of fun.  Thanks again to both of you.
