Hey Adam,

[Is your router frame a parallelogram? Mine was!](https://forum.onefinitycnc.com/t/is-your-router-frame-a-parallelogram-mine-was/6086)

For the machine to be rectangular (“squared”), the diagonals have to be equal, you can ensure this with a method [like this](https://forum.onefinitycnc.com/t/is-your-router-frame-a-parallelogram-mine-was/6086/61). Note that the length of the Y rails on left and right have to be equal too!

This is very likely. I would check if the problem disappears after making sure the machine is accurately rectangular.
