All set up but now accuracy is weird

I created a 4 inch by 4 inch square, then when I cut it, it came out 3.5" x 4.5". How can I tighten this up and reign it in? What settings should I be looking at?

What frame, what Maslow, what hardware, what software and how did the calibration go?

It’s resolved now, just had to rerun the calibration.
