If the machine is cutting parallelograms where rectangles or squares were desired, the problem may be machine squareness.

This error is typically consistent and has a magnitude of 0.010" to 0.100", but depends on the size of the whole part.

One way to test for this is to:

• Cut two large squares or parallelograms
• Flip one piece upper right corner to lower left corner, top-side-now-down.
• Lay the parts over each-other in this orientation
• Compare opposite corners. If across one diagonal they are too long, and the other, they are too short, you likely have a squareness issue.
