Won’t be standard if it’s still using an Arduino firmware… There are more Marlin forks than there are in my grandmother’s silverware.

That’s what the bed probing and bed leveling is for, no?

No, if your Z is not orthogonal, it would assume that the surface is not level and compensate for it - it’s what the bed leveling matrix does… How it works if the gantry is also tilted at a 20 degree angle though, I don’t know.

Err… Right, I see what you mean, because your first reference point would always be at the same layer height.
