4.2.2 Levelling the heated bed
To make 3d printer have better printing result, levelling bed before printing.You can
refer to these steps to levelling the 3d printer.
Before you levelling the heated bed, please make sure gantry frame is perpen-
dicular to Z axis aluminum extrusions, you can calibrate the couplers to make the
frame same scale on both Z axis aluminum extrusions.
The recommended distance between the nozzle and printing surface is
0.05~0.1mm(Thickness of A4 paper). There are 4 knobs under the heated bed,
by which you can tighten or loosen the springs to reduce or increase the distance
between the nozzle and printing surface. The distance from nozzle will increase if
you tighten knobs, otherwise, it will decrease distance from nozzle.
Step1: Click “Prepare”→“Auto home”→“Disable steppers”
Step2: Manually move the extruder to the 1st right hand corner of the heated bed,
you need to place a piece of A4 paper between the nozzle and the heated bed,
fine-tuning until you feel slight friction from the paper when you pull on it(Repeat
for all 4 corners and centre of the bed)
