The “Blocks zero” product consists of a 3D printer assembly kit. For assembling the kit, the
user must follow the assembly manual strictly. This electro-mechanical equipment is in-
tended for the creation of digitally shaped parts or models through the deposition of mol-
ten thermoplastics. Despite the quality we believe we have achieved with this machine,

1. Blocks Zero should always be used with the power supply supplied with the printer.
2. Never use damaged power cords.
3. This machine have moving components that can cause injury if handled while the printer
is operating.
4. The nozzle in Blocks Zero operates at high temperatures, so it should never be touched in
the heating and cooling processes or while the machine is printing.
5. Never access the electronics area while the machine is connected to the power supply.
6. Do not use the printer in explosive environments or near chemicals that may react to
high temperatures or electrical surges.
7. Do not leave liquids near the printer.
8. The printing process should always be supervised.
9. The printer should be installed in a well-ventilated area, as vapors that are harmful to
health may be released during the printing process. The recommendations of the material
manufacturer must always be followed.
10. Do not install the printer in direct contact with solar radiation or in an environment that
may exceed the recommended operation temperature, It may occur deformation of
some printed parts that can cause damage to the equipment.
11. Note the following symbols:
This symbol indicates the presence of moving parts inside
the machine.

2. Open the carton box by the correct side marked with a sticker.
3. Carefully remove the top components, the toolbox, polished vertical axis rods, and acrylic
panels. Take special care to remove the acrylic panels as these are fragile.
4. Follow all assembly steps of the machine inthe correct order as described in the assembly
manual.
5. During the assembly process, if any components are missing or damaged, contact the
dealer where you purchased the equipment immediately.

04.2 Plate leveling
Plate leveling is one of the most important processes in 3D printing. By making sure the
printing platform is leveled, you are ensuring that the entire surface of the plate is at the
ideal distance to the nozzle.

3. If you choose to clean the nozzle, wait while the Hot End reaches the required temperature.
After the cleaning is complete press the button to start the plate leveling, but wait until
the hotend reaches a safe handling temperature (<50°C) before proceeding to the next step.
4. Place a contact card or a paper with similar thickness between the nozzle and the plate.
Adjust the plate screw adjacent to the nozzle until you feel a slight friction when sliding
the card or paper between the two components. Press the button to continue.
5. Repeat the previous step for the second point.
6. Repeat the previous step for the third point.
7. In the last step, the nozzle moves to the center of the plate and the user must place the
contact card between these components again and ensure that the friction when sliding
the carton is as close as possible to that of the previous steps. Press the button to end this
process.

The Blocks Zero printer gives the user the option of controlling various parameters directly
on the machine, either in standby mode or during printing.
1. Auto home - Serves to reposition the print head at the origin of the spatial coordinates.
2. Move axis - Allows the user to activate the motors and thus move the print head on

ment extruder if the Hot End is at a temperature which allows extrusion (>180ºC).
3. Disable steppers - this option allows to unblock the stepper motors when they are in standby.
4. Temperature - here the operator can directly change some print parameters. Whether
in standby mode, during printing or in maintenance and cleaning operations, the Hot End
temperature and the cooling blower speed can be set or changed. You can also acceler-
ate the cooldown of the Hot End.

05.1 Removing objects and cleaning the build plate
The roughness of the build plate on the Blocks Zero provides optimum adhesion. It is not
necessary to add glues, lacquers or other similar products, just ensure that the plate is lev-
eled and at an ideal distance from the nozzle. To remove the printed objects you can bend

the plate between prints. To clean it you can use water or alcohol and can also resort to a
spatula or x-acto if necessary.
05.2 Cleaning the Nozzle
After several prints it is normal for the nozzle to show some dirt due to the accumulation of
plastic debris. To clean it it is necessary to set the nozzle temperature to 220ºC. After reach-
ing this temperature, the operator can use a dry cloth or cleaning paper to remove the dirt.
