It sounds like your having bed adhesion issues. Start by manually leveling your bed then calibrate the bltouch or whatever auto leveler it has. Then you'll have to calibrate the z-offset.

You can also try using some hairspray on the bed to help with adhesion. There also some stuff called magigoo that works well but is pretty expensive.

Calibrating a new printer is very time consuming and confusing if you don't know what your doing.
