<snip> Isn't the math: I(relative) = I(absolute) - X(start) J(relative)=J(absolute)-Y(start) ?
Carl Helquist Hello Carl Your math's is right (I think so) However your assertion in my ability or inclination to write a script or program, sorry wrong. Best wishes Dave </snip> If that math is correct then couldn't you simply use Gedit (or your favorite editor) and do a replace and whenever I or J is encountered change it to subtract the variable stored for the current X or Y position from the I or J value ? (I haven't rooted around in the variables list recently but I'm pretty sure that the current is stored as a variable). If scripting (which is a lot easier than you might think) isn't your thing then it might be worth a shot. Learning a little bit of programming even at the basic levels can help out a lot in your future exploits. I'm tired and probably missing something but I've used the Find/Replace dialog to make wholesale changes to G-Code, of course I always preview it before running it. So tell me what I know I'm missing but I can't put my finger on right now...
