I have just bought a Creality Ender 3 Pro. During setup, I think I must have applied an offset... The nozzle lifts up about 5 mm from the bed when starting to print.

I am reading that M502 resets to factory settings and M500 saves the settings. I have looked everywhere I can think of but am unable to find these files to download. Can someone help me please? Where can I find these files?

    What "files" are you talking about? If you mean the `M502` and `M500`, those are commands that are sent to the printer. More info can be found at [What is a printer console/terminal?](https://3dprinting.stackexchange.com/questions/10573/what-is-a-printer-console-terminal). – agarza Nov 25 '21 at 17:42

M502 and M500 are not files, they are G-code commands (well, they are actually M-codes, but don't worry about that)1.

To reset your printer to the factory default settings, simply connect a terminal and send M502.

If you are using Linux, see How to directly send G-code to printer from a Linux terminal?

See also M502 will reset all configurable settings to their "factory defaults", which settings are those?

1 Simply put: G-codes control movement; whereas M-codes control other functions (which aren't movements).
