1. Product manual
Before you use the printer, please first finish the installation. Before the installation, please
carefully read through manuals of installation, manual leveling etc. After the installation, please
carefully read through the manuals again to check if the printer is correctly installed and correctly
wired. If it is not correctly installed and wired, it may lead to machine malfunction.
Safety note:
Hotbed and nozzle are high temperature parts, do not touch in case of getting burnt.
Power supply part has potential danger, touching may lead to harm.
Attention:
1. For the printer, please prevent contact with water and other liquid. Otherwise, it may lead to
machine damage.
2. When loading the model, please do not turn off the power. Otherwise, it may lead to data loss of
model.
3. During the printer debugging, there will be filament coming out of the nozzle. please make sure
there is at least 50mm distance between the nozzle and the printing platform. Otherwise, it will
lead to nozzle blockage.
4. Normal working temperature of the printer is room temperature, and humidity 20% - 50%.
Exceeding the range can affect forming quality. During the operation of the equipment, there may
be odor in the extrusion process due to material difference. Please keep the air well circulated. If
you feel discomfort, please stop using immediately and seek for corresponding treatment in the
hospital.
5. The SD card supports FAT32 file system. You can store G-Code into it for offline printing.
6. One of the keys to successfully print a model lies in the printing platform. If you are using ABS
material, hotbed platform should be preheated to 90 degrees Celsius, keep the hotbed platform
clean to increase adhesion. If you are using PLA material, you can apply glue (recommend UHU
glue) to the hotbed platform, or preheat hotbed platform to 50 degrees Celsius.
7. During the printing, temperature control of nozzle is also important. If you are using ABS
material, recommended temperature of nozzle is 220-240 degrees Celsius. If you are using PLA
material, recommended temperature of nozzle is 80-210 degrees Celsius. Please set up the
temperature according to material during actual printing.
8. Please note the baud rate is 250000 when connecting the printer to the computer.
9. When you print for the first time, first tighten the nozzle; when the temperature reaches 170
degrees, tighten the nozzle again. In this way, blockage of nozzle will be unlikely. Also, change
the step per mm to 92 as below picture.

2
10. To make the forming quality better, please set up a reasonable printing speed. Higher printing
speed can reduce the printing time, but can result in poor forming quality; lower printing speed
results in longer printing time, but higher forming quality.
11. After using the printer for a period of time, you need to check critical parts such as the
synchronous belt, push rod and screws if they are loosened.

3. Technical Manual for Installation
I. Installation procedures
ROSTOK 3D printer is easy to install due to its simple hardware structure. Below
are some tips and suggestions for installation.
Before installation, please keep necessary tools on hand. Tools needed are a set of allen
driver for repair, M3, M4 screw tap, nipper pliers, wire stripper and etc. Please be careful
with the pressure you apply during installation in case components were damaged due to
overexertion.
The mechanical structure of the printer is mainly comprised of slider, acrylic board, fixed
units, belt and various attachments. Each component has its own specific installation
position and plays an important role, so please be sure to install in a proper way. You must
also pay close attention to installation procedures. The whole printer structure is not
complicated indeed, but if you don’t follow certain steps, you might risk wasting lots of
precious time. Now let’s move on to specific installation procedures and methods of
ROSTOK 3Dprinter .
