Yup! Here is a tutorial on it and the grid file: Grid update and more free cutout files
The easiest way I have found to explain it is the calibration print for a new print head, which is a 20 minute print that “aligns the printer head with the rest of your printer”. So if it takes 20 minutes for the machine to align with the print head, then you know it is not doing it each time before you print. Meaning that your machine already has your print head mapped out to the machine and is using the information from the print head setup any time you print. So with the grid method, you are basically asking your machine to show you where it understands the coordinates to be.
