Seem like as I’m moving toward the left hand side of the bed, the tolerance will get more true.
For some odd reason, couple hours later as I was making a video to show my seller the tolerance swap side from left to right.
Machine inspection:
-Machine age 5 weeks
-Controller RDC6442G-B(EC)
-X/Y axis are calibrated to the .002in
-Belt aren’t loose
-Bed is level
It sounds strange, but check your supply chain for the laser head, I have had a very similar problem which turned out to be too short / tight supply chain.
… and of course you have checked all the mirrors and the lens to see if it is tight. What about your timing belts, could there be any stuck dirt in a particular place?
If you draw the largest possible square, you can easily measure the diagonal difference with a tape measure. Maybe you can not measure it in thaw part but you will at least get a best possible indication.
