5.2 Coarse tuning of distance between the nozzle and the hotbed
*If the nozzle is far from the surface of hotbed, loosen the M3x50mm screw to extend the bottom
part.
Then the printer will home at a relatively lower place, the distance between the nozzle and the
hotbed will be decreased.
*If the nozzle is too close to the surface of hotbed, tighten the M3x50mm screw to shorten the
bottom part.
Then the printer will home at a relatively higher place, the distance between the nozzle and the
hotbed will be increased.
You may need to calibrate for many times at this step.
The recommended distance between the nozzle and the hotbed is 0.5-1mm.
