3.7 Z Axis Subassembly

Z axis subassembly drive the hot bed to move up and down. Z axis subassembly can be maintained by

removing the rear lateral plate.

The trigger plate of photoelectric sensor has been in its position, no further adjustment by user is required.

Only when there is any problem in manual leveling of the hot bed, users may be required to inspect and

adjust the position of the trigger plate. Upward adjustment of the trigger plate of photoelectric sensor can

make the zero point of hot bed move downwards, and downward adjustment of the trigger plate of

photoelectric sensor can make the zero point of hot bed move upwards.

3.8 Castersand Skirt plate

There are 4 casters under the machine, which are used for the short-distance movement in door and the

adjustment of orientation. They shall not be used for long-distance movement out door, otherwise the

casters may be damaged.

Clockwise turn the casters to make them in movable state, and anticlockwise turn the casters to make

them in locked state. After the placement position of the printer is confirmed, the casters shall be kept in

locked state, otherwise the printing quality may be impacted.

During long-distance transportation, the printer shall be placed on support plate first before being

transported by forklift. Be sure not to transport the printer by forklift directly, otherwise the bottom of the

printer may be damaged.
