Charlie,
Thank you for responding so fast! I preface this by saying , that I'm still newish at this. I will explain my workflow, and maybe you have an insight into what I'm doing wrong. So, I have a photo I want to carve a half tone of in to a piece of wood. I feel like the thickness of the wood itself is arbitrary since I am just essentially making marks. I set the canvas properties to 5x7 with a Z size of .040" and a Z origin of 0.00. I import an image same size as the canvas , invert it, set the Z Size to .040" and the Z origin at 0.00. Z fill for both is set at zero. I set up a Spiral Carving operation with a 60 degree V-bit set at .06" step over, min depth of 0.00 and max depth of .040" and .1" rapid height. When I simulate the operation it looks money. output the gcode - this is the first few lines

It seems like its adding the thickness of the canvas to the rapid height? Anyway, when I go to machine the image, it seems like the bit is hovering by about that much (.14") over the work piece. I have an xcarve, and I use the metal puck to set the workpiece zero. So, you're saying that if I add just the G53 command at the beginning of my code it will negate the "G0 Z0.14000"? I really appreciate your help with this!
Kind regards,
Michael
