I.ve started learning about this g-code, and did some basic cuts. Today I.ve uploaded a greyscale image in artcam and set a 3d relief toolpath with 2 cutters for the job, and generated some code for carving a 10 by 10 cm horse. It has 816 lines of code, but the program always stops at line 500. I assume I should change the tool at this point. It just stops and refuses to continue, no matter what I do.
Reading about this, most sugestions are about editing a file called m6start.m1s. I.ve done this with all the scripts I could find and still could not make it work.

I.m hoping to make the cnc stop, come to a defined position to let me change the tool, rezero the z, and continue from where it left.
So, how do I do this?
