router adjustment
take a 6 inch piece of 1/8 diameter wire and bend the last half inch of each end 90 degrees to make "sort of an S" ... insert it into a 1/8 collet so you can rotate it above the table ... as you rotate it above the table manually, it the router is vertical, the end of the wire will be the same height off the table in all 4 directions ... use some sort of flat stock as a feeler gauge ... adjust as needed
... years back some guy made a bracket and a few set screws to adjust the router, sort of like a pool table
The decimal point seems to be the most important on the z axis... x & y not so much....
