Trying to learn something new. I've always zeroed from the top of the material for everything. I now want to zero from the spoilboard for my profile cuts. So I put the zero plate on the spoliboard and zero as normal. Now I need to tell the machine how thick the material is, right? So I need to change the number in the Zero space to a negative number coninciding with the thickness of the material, correct? How do I go about this? I've played with the Zero tab but can't seem to find it there. Any help, maybe crayons and construction paper, would be appreciated. Thanks!
