General Safety Information
This User Guide contains important safety directions that should be followed during installation and operation of Robo
3D printers. It also includes warnings against negligence and misuse that could cause damages or injuries.
It is essential to update the firmware so as to avoid any kind of failures. Visit our website: https://robo3d.com/ regularly
to see the latest news and updates.
Robo 3D printers operate at high temperatures and have easy to access movable components, therefore, you must be
particularly careful when handling or operating the devices. While operating the printer, it is extremely important to
avoid situations that may lead to burns or interference in proper functioning.
Do not leave the machine unattended during the print job - check it periodically for proper functioning in order to avoid
potential accidents or failures. Turn off the printer once the print job is finished. Monitor your printer for wear and
tear regularly. Contact our Support Center at: http://help.robo3d.com/ for assistance while replacing worn or broken
parts.
Keep the printer away from heat sources, fire, flammable materials, humidity as well as water and other liquids. Place
the machine away from any equipment emitting radiation. To prevent any inadvertent use, keep the device out of reach
of children and animals. Do not shake or drop the printer as it may cause the printer to fail in performing as expected.
Health and Safety during operation
All service and maintenance activities as well as device operation require wearing safety gloves included in the Starter
Kit. Wearing safety gloves is also advised while removing the finished print from the platform.
The vapors released during the printing process are not hazardous, however, it is important to ensure proper ventilation
in the print room.
Food and beverages should be kept away from both the 3D printers and 3D printed objects. While operating Robo
devices, all measures regarding health and safety provided in this User Guide as well as in separate regulations should
be taken into account.
Electrical Safety
The Robo C2 3D printer has been tested for compliance with Low Voltage Directive. In order to ensure the high-
est safety standards, including protection against short circuit, overload, overvoltage and printer overheating, do not
attempt to modify the printer and do not use electronic replacement parts other than those recommended by the Man-
ufacturer.
Replace electronic units according to the instructions and be particularly careful while using the tools supplied with
the printer.
Before plugging the power cable into the outlet, make sure that the power supply voltage in the outlet matches the
required value provided on the nameplate at the back of the printer. Avoid overloading the outlet with too many
devices.
The printer must be well-grounded. Always make sure that the ground complies with local and national regulations.
Use only the original power cable supplied with the printer. Do not damage, cut or repair the cable. A damaged cable
should be immediately replaced with a new one.
All maintenance and repair work should be carried out while the device is off and unplugged. Do not expose the device
to moisture and liquids. Modifications such as soldering of electronic subunits are forbidden.
Mechanical Safety
Robo 3D printers have movable components, such as the drive belts, Z-axis screw, extruder or build plate. Therefore,
do not reach into the printer or put anything inside the printer when it is running, about to start running or at rest. This
may lead to serious injuries or damages.
Tools and accessories from the Toolbox should be used with special care for intended purposes only. Improper use
may cause serious injuries.

C2 User Manual, Release 1.0.0
Removing the prints from the platform should be done carefully so as to avoid injuries.
Risk of Burns
There is a high risk of burns while operating Robo printers as the hotend’s temperature may reach up to 3000C [5720F].
Do not touch the hotend with bare hands. Be extremely careful during maintenance and repair work of heated units.
If it is necessary to touch a heated component, use the pliers which are specially adapted for this purpose. Cooling of
components should not take less than 30 minutes.
Electromagnetic Compatibility (EMC)
Each Robo printer complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1)
this device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with this instruction manual, may cause harmful interference to radio communications. Operation of this equipment
in a residential area is likely to cause harmful interference - the user will be required to correct the interference at their
own expense.
The EMC test report for the Robo C2 or the Robo C2 is available on request at [email protected].

Printer -The print screen is the default screen when printing. This will show you file printing, extruder temperature,
a progress indicator, and pause and cancel buttons while in use.
Utilities -The Utilities menu offers a variety of options including: motor control, temperature control, z-offset wizard,
network settings, and a way to update your printer
2.2 Setting the Z offset
Here we will calibrate Robo C2 by setting the Z-Offset and making sure your first layer is applied correctly. We will
be covering three ways of zeroing in on your Offset. The first is the Z-Offset Wizard found in Utilities> Wizards;
the second is the Fine Tune Wizard - also under Utilities> Wizards; the final is manually adjusting your Offset in the
EEPROM manager.
What is “Z-Offset”? Simply, its the distance between your nozzle and your print bed when the print bed is at home
(bottom of printer), which is technically known as a Home Offset. This offset can change by not seating your print
bed correctly or a shifting hotend.
2.2.1 Z-Offset Wizard
From the home screen select “Utilities”
Then select “Wizards”
