Just for giggles, I tried cutting a 40mm square. Got 36.35 on the X and 36.5 on the Y. I’m still using rotozip bits, so they’re kinda long, and downcut 2 flute, so that may have something to do with it. Real endmills get here maybe Friday. My lower outside bars are 5.25 inches from the table, with a half inch spoil board on top of that. If I want to go lower I’m going to have to cut the leg tubes, they’re touching the bottom panel of my table.
