Hotbed height calibration
For a proper use, the nozzle movement must be parallel to the Hotbed Surface.
To achieve that, there are three screws available to calibrate its orientation.
There is a risk of the nozzle hitting the hotbed glass so the first layer not sticking on its surface when the base is decalibra-
ted. The following steps must be followed:
1. Click on Autohome (Prepare > Autohome) so the printer axes move to their initial position.
2. Tighten the three M5 screws located on the printing surface to compress the springs holding the base in order to
lower it.
3. Untighten the same screws five turns so the nozzle does not collide with the glass in preparation for the next step.
4. Click on Prepare > Move Axis > 1 mm > Move Z to move the extruder platform to Z: +000.00 mm.
5. Move the nozzle closer to the X tightening screw following the glass surface. To do that, click on Prepare > Move
Axis > 1 mm > Move X and set it to X: -085.0mm.
6. Untighten once more the closest screw until the nozzle tip is 0.2mm from the glass. Use a folded paper to check
the distance, at 0.2mm it should slightly graze both the nozzle and the glass.
7. Move the nozzle close to the front tightening screw. To do that, click on Prepare > Move Axis > 1mm > Move X and set it
to X: +060.0mm and in menu Y set it to Y: -060.0mm.
8. Repeat the levelling process using a folded paper.
9. Move the nozzle close the rear tightening screw. Follow the same
procedure and use the values X: +045.0mm and Y: +060.0mm.
10. Repeat the levelling process using a folded paper.
11. To finish up, move the nozzle back to the first screw leveled using
the values X: -085.0mm and Y: +000.0mm.
12. Once again, level it using a folded paper.
