I am trying to get Bobcad to get me a basic can cycle to work. First off it wasn't entering M03 so I manually added the text. I set the tool with the probe, then did a Z face measure to set the offset in G54. When I ran the program it looked like the depth was way to deep to start so I changed the X in G54 to 0.4, it ran ok but it still didn't get me to the correct diameter of the part. I made the correction to the of set to .356 and the part was dead on. It takes such a deep cut right off the bat that the tool pushes the stock into the chuck.

What I could use help with is;

What should the X offset in G54 be based on this program?
Why is it taking a .1 cut right off the bat?

Thank you, Prescott
