This can be adjusted by using the Z-Offset from the LCD menu

I think I'm possibly too much of a noob to go rebuilding the printer to add levelling sensors. I'll need to get a bit more confident before I venture into that.

As far as I can see there is no native z-offset setting on the Mega S. Should I level the plate using a very precise thickness of paper, or is there a command I can instert into the g-code file to execute the z-offset for each print?

This was another useful vid I hunted down just now: https://youtu.be/6QhUgq4C008

Many thanks for the guidance.
