Laser calibration troubles

circles are looking better, but still off by about a .25mm, calibrated movement so its making an exact 100mm box. But the corners don’t touch and the circles dont close. This is a new machine btw. fox alien masuter pro with 10w laser.

So far I did find the wheels were very tight making it hard for the y axis to move, now it moves smoothly by hand.
