I am new to X-carve. I was thinking of added a 1/4" piece of plywood the same dimensions as my 3/4" piece that I am going to make the though cuts on. When I add the 1/4" piece under my work piece, will that “undocumented” 1/4" piece mess up the carve when I go use to z-probe to zero the work? This is probably a dumb question just very unfamilar with Easel and X-carve and trying to learn. I also don’t want to mess up the wasteboard by accidentally cutting into it. Thank you ahead of time!
