Rotate the platform leveling knob counterclockwise to
lower the platform
In coarse tuning, the approximate distance between the
nozzle and the glass plate is the thickness of a piece of paper.
If the distance is too great, the platform leveling knob should
be rotated clockwise to move the platform upward. If the
distance is too little and the nozzle is too close to the platform,
turn the leveling knob counterclockwise to move the platform
down.
