Error message: cut start is above rapid clearance plane

I have a new system. Have had some good success, but keep getting this error message with Sheetcam: cut start is above rapid clearance plane. I do not have the z axis on my machine, and have the height settings pierce height, plunge rate and cut height set to 0. Any suggestions on what to check? Thanks, JoeO

Do you have your x axis zero set to top of work in sheetcam? I’m just guessing here.

I think I fixed it by making the rapid height higher. At least I think this may be what I did. Thanks for the quick reply and help.
