2.2 Coarse Tuning of distance between the nozzle and the hotbed
*If the nozzle is far from the surface of hotbed, loosen the M3x35mm screw to decrease the
distance between the nozzle and the hotbed.
*If the nozzle is too close to the surface of hotbed, tighten the M3x35mm screw to increase the
distance between the nozzle and the hotbed.
You may need to calibrate for many times at this step.
The recommended distance between the nozzle and the hotbed is 0.5-1mm.
