BFB-3000 Set Up and Operations Manual
 Press Z+ to reduce the gap between the hot end and bed to approximately 2 mm.
This will enable finer levelling.
 Repeat the levelling process.
Caution: Observe each extruder movement. The nozzle should not
touch the bed. Moving the extruder with the nozzle touching the bed
will damage the nozzle and the bed. If the nozzle touches the bed,
immediately lower the bed using the Z- button.
 Finally, check the centre location of the bed by pressing Y+. This can be used to
identify an excessively worn or warped print bed as the height in the middle will
differ from the perimeter of the bed.
 Press Escape to leave the function, and return to the main menu.
