Step 2 Checking homing functions
The X/Y/Z mechanical endstops are installed at the
x
= 0,
y
= 0, and
z
= 0 position,
respectively. During homing, whenever the X/Y/Z endstop is triggered, the motor(s)
in that axis will be stopped and the position of extruder’s nozzle tip will be registered
as the origin of that axis.
•
Click the “Home X” icon. The extruder will move to the left until it triggers the
X-axis endstop.
•
Click the “Home Y” icon. The HBP will move backwards untill it triggers the
Y-axis endstop.
•
Z-axis homing will be tested in the next section when leveling HBP.

Leveling HBP
A 3D object is formed layer by layer by extruding the melt filament onto the last layer of
object. The first layer of object is directly printed onto the printing surface. In order to
