I have checked and adjusted sqaure for the x-y axis. I used a metal dowel rod centering tool, plunged it into the spoil board at 0,0; 0,53; 113,0 and 113,53.
I then measured diagonally from from point to point and found that the diagonal opposite to 0,0 was 4mm greater.
I snapped a line connecting the two dots 0,0 - 0,53 and then 113,53. Then I did the ole 3,4,5 square check. It was off about .03"
I tried adjusting the y-car in an attempt to improve this without luck. If I'm looking at this right, that says the machine is out of square 0.03" over 12 feet. Am I trying to achieve a result that exceeds the machines resolution?
