I was happily going along cutting stuff on my Sphinx 1050 not knowing how out of square it was. Then I tried out the surfacing gadget (nice software Peter) with a 1 inch mortising bit. I can now go into the roofing business. This thing shingles like crazy. The "NOD" I believe it is called is out about a 1/16 of an inch. Its leaning forward. It didnt show up until now, the drilling was ok (i thought) I was drilling 1/8 holes .5 deep for cribbage boards, You wont see anything wrong there. Also 3d carving again nothing real shows up. Anyone know how I can adjust this?
