Why do some 3D printer beds require turning knobs on the bottom for leveling? - eviltoast

On my ender 3 I have to turn the knobs on the bottom for leveling.

I just picked up a Bambu Lab P1S and it doesn’t.

Fundamentally, what is different that allows the P1S and other printers to get away without it?

    The knobs get you “close enough” and then the touch probe accounts for the rest. You wouldn’t want your extruder to have to move up and down 1mm for each layer if it was really far off.
