3. STARTUP PROCESS
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’s a risk of the nozzle hitting the hotbed glass or the first layer not sticking on its surface when decalibrated. The
following steps must be followed:
1. Click Autohome (Prepare/Autohome) so the printer axes move to their initial position. The first time, caution
should be exercised because the nozzle can collide with the base plate. If it is anticipated that this will happen, ma-
nually press the Z axis end stopper.
2. Adjust the screw triggering the endstop so the nozzle almost touches the glass when clicking Auto-home.
3. Tighten or loosen the three black screws leveling the base plate. The distance between the nozzle and the glass
should be 0,2 mm. (Tip: use a folded paper to check)
4. Position the extruder in the left side using your hand (in case any resistance is felt, disable the stepper motors
using Prepare > DisableSteppers). Level the base plate once again using the same procedure.
5. Move the base plate to the front to level the rear end of the plate.
6. Repeat the process until its four corners are leveled.
