Hey all, I am near completion of my all aluminum data-cut router. I was wondering what kind of tests I can perform to check out its accuracy/repeatability and how to perform the tests.
Here are some thoughts:
(1) testing square in x, y and z
(2) testing for backlash (if any)
(3) testing for precision across the table
For testing for square in X/Y, I was thinking of a series of 6"x6" boxes around the table, then measure with calipers.
For testing square in Z, mill a deep thru hole and measure roundness (not sure if this will be of much use if the table is a bit out of whack.
I suppose for testing precision across the table, I could just make small boxes with a precise pen in the tool holder at the extremes of the table. Repeat them and see if they line up.
thoughts? comments?
