Using the stock 0.125 cutter with a 5mm acrylic sheet, I used the default parameters to cut out a 1" x 1" square with a 0.5" diam hole in the center. Measuring with calipers, the part came out as a 0.990" square with a 0.507 diameter hole. When I measure the diameter of the cutter, it is undersized, but the resulting path is oversized. I make custom cutter settings setting the bit diameter to 10 thou larger and the new result was 0.998" square and a 0.498 hole. Does one need to change the apparent cutter diameter for different types of material? Or is there a different setting I should be using to compensate to improve the dimensional accuracy? Thanks for any feedback!
