Tevo Michelangelo nozzle below build plate?
Just move the Z-endstop up a little higher, also make sure the bed leveling screws are not completely screwed in.

So:


Move the head of the printer up.
Move up the Z-endstop so that the nozzle is a little higher than the build platform.
Home the printer.
Disable the stepper motors and move the head over the bed to a certain position (e.g. a corner without disturbing the Z axis), once you get to a new position of the bed, raise the bed by unscrewing the screws until a piece of paper shows noticeable drag when pulled between the nozzle and build platform.
Goto 3 until you have done all corners several times, also the center of the bed. It is advised to once in a while re-home the printer, this way accidental Z-axis movement is compensated again.
