Safety Instructions
Building your printer will require a certain amount of physical dexterity, common
sense and a complete understanding of what you are doing. These detailed
instructions have been provided to help you easily assemble your 3D printer.
However, we cannot be responsible for your health and safety whilst building or
operating the printer, with that in mind be sure that you are confident with what you
are doing prior to buying and commencing to build your 3D printer. Before you
begin, read this entire manual so you are aware of all the individual steps and to enure
that you are confident that you can complete this task before you commence to build
your 3D printer.
Building and operating your 3D printer involves working with electrically powered
equipment, so all necessary precautions should be taken and adhered to. This printer
operates on 12Volts which is supplied by a certified power supply, so you shouldn’t
ever with voltages exceeding 12V but bear in mind there can still be high currents
involved and even at 12V extreme causation and safety awareness should be taken at
all times.
3D printing involves high temperatures. The Extrusion nozzle of the hot end can run
about 230°C, the heated bed runs 110°C and the molten plastic extruded will initially
be at around 200°C, so special care and attention should be made when handling these
parts of the printer during operation.
It is not recommended that you leave your printer running unattended, or at least until
you are confident to do so. We cannot be held responsible for any loss, damage,
threat, hurt or other negligent result from either building or using the printer.

Preparation
1. Unpack the kit and check that all parts have been supplied with the kit.
Check the condition of each part as there might be some damage during
shipping. To help you with this procedure we have supplied you with a bill
of materials (BOM) which can be found in the box. Each part has been
packed in a bag with an easily identifiable part number.
2. Should you identify damaged, missing or incomplete parts, please contact our
customer service immediately by email or through the website. At the bottom
of the BOM, there is a signature of reviewer, please take a picture of it and
attach the picture in your mail.
3. Read through each chapter of these instructions to gain an over-all idea of
what is involved and how long it might take, before starting on the work
described.
4. Before you start, you can sort all the parts in order, this will save you time
especially when trying to identify individual screws and nuts. Take care not
to mix up these parts as they may appear to be very similar to each other.
5. Ensure you have the necessary skills to carry out the work, or enlist the help of
someone who does.
6. Work on a big firm table or bench in a clean dry well-lit area.
7. This kit contains tiny parts; please keep them away from kids under 3.
8. If you run into problems, ask for help –our contact details are on our website
and we will always do our best to resolve any problems you may encounter
quickly and efficiently.
9. Due to parts upgrade and production batch is different, the pictures on the
manual might be a bit different with what you actually received, but the
function and installation will not be change. Geeetech reserves the right to
explain.

Step 2. Mount the pulley on to the motor shaft. One of the screws should be
screwed on the flat section of the shaft –ensure to screw them tightly, be
careful not to damage the screws.
Note:Pulley looks different here in the picture, but it will not affect the assembly and
use.
Step 3. Mount the 3 motors to the assembled motor holders. Fix them with the
M3x12 screws (#19) and M3 washers (#5).
* Note: It is better to have the wire connector mounted so then it is facing either left
or right. Do not mount it so the connector is facing up or down as it will
interfere with the base or the table.
