In this video we're going to calibrate our XY & Z Steps that will make our prints more dimensionally accurate. This is going to give us spectacular results on assembled prints. If you're running more than one printer, it'll will help to make sure that parts from the different printers will all fit together properly. It's also going to help us eliminate deformed parts. For example, if you're trying to print a cube and it looks more like a rectangle, there's a good chance that your XY & Z steps are off. It'll also help us get better top layers by making sure they are flush and not sticking above or below the side walls. Remember, you'll want your eSteps and flow rate determined before performing this calibration. I have videos on my channel that can guide you through those steps if you haven't done them.

NOTE: Typing error at the 4:15 mark in the video! The formula for the Z axis should read

(400 x 40) / 39.88 = 401.2 instead of (80 x 40) / 39.88 = 401.2,

I would fire the editor for not catching this but unfortunately I'm a one man show!
