Top offset bottom offset

So when you enter the offset values top & bottom and say your material is 3/4 thick, do you enter 13/16 or try i don’t think it let me in Carveco .So as to make sure it cuts through in case your stock is not perfect or leave it alone??

My methodology is to adjust my zero based on what I’m doing.

If I’m doing a through cut, zero off the wasteboard. Then it doesn’t matter if your stock is a little thinner or thicker than your model.

If I’m doing a pocket or engrave, zero off the top.
