I am trying to produce the Eagle Box project that I purchased from CarveWright. When my machine begins cutting the pattern out, the left side of the pattern is more narrow than the right side (It's even in the software). In other words, if looking at the board length-wise, the pattern is cut unevenly on the left than the right. Any thoughts on what to do and how to troubleshoot the problem? It only happens when being cut out. Using 1?8" cutting bit and using Poplar right now as a test wood.
