I have this job I am carving for a donation. They were given a Mahogany tree and I though a plaque might be a good idea. Unfortunately the carve has a y axis error at 17" into a 19" carve. The 19" board is in a sled.

When I try to make a zero cut box (new at it) for the first 16 1/2" then insert the board. Do a measure fine, then when I go to carve it. It goes through the bits, then after it is done it stops saying "cut depth exceeded"

Help what am I doing wrong. Can someone make me a zero cut region or what ever is done so I do not have to re-carve the first 16 1/2"

Mohagony plaque final.mpc
