Safety Instructions
Building the printer will require a certain amount of physical dexterity, common sense and a thorough understanding of what you are doing. We have provided this detailed instruction to help you assemble it easily. However ultimately we cannot be responsible for your health and safety whilst building or operating the printer, with that in mind be sure you are confident with what you are doing prior to commencing with building or buying. Read the entire manual to enable you to make an informed decision. Building and operating involves electricity, so all necessary precautions should be taken and adhered to, the printer runs on 12V supplied by a certified power supply, so
you shouldn’t ever have to get involved with anything over 12V but bear in mind
there can still be high currents involved and even at 12V they shouldn’t be taken
lightly. High temperatures are involved with 3D Printing, 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. We wouldn’t recommend leaving 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 if all parts are in the box and check the condition of each part, there might be some damage during shipping. To help you with this, there is BOM in the box and each bag was labeled with part number.
2. Contact our customer service immediately by email or through the website if you find any missing or damaged parts. And on 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 put all the part in order to save your time especially those screws and nuts. Do not mix them up.
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. Ask for help if you run into any problems - our contact details are on the website and we will always do our best to resolve any problems encountered.

Tips:
1. Before assembly, you are advised to put all the parts, especially the screws and nuts in order, which will save you a lot of time looking for the required parts.
2. The part ID is corresponding to the number labeled on the bag of every part. Some parts may not have label, you can refer to the pictures on the package list.
2 Assemble the rods of a Y axis
Watch the video
Step1. Assemble the 2 threaded rods.
Thread the nuts and washers into the two M10 threaded rods separately. The order should be:
1) Thread the Y plate connecting plate A14 in the middle.
2) Thread the M10 washer > M8 spring washer >M10 nut > M10 nut > M10 washer

* Tips: Try to keep the rods parallel and the four acrylic pieces parallel. The Y-axis
must be a rectangle, that is the rods on both side should be parallel, so is the front and back plate. Otherwise it will cause obstruction for the belt later. You can use a Digital Caliper to measure. *Note: As we re-designed the rear plate, there are two more holes on A12, in this
case, you need to use the screw locking ring to fix the smooth rod.

Keep both end of X axis at the same place of the rod, you are advised to measure the distance of the both side so that they are at the same level when you put them up.
Step2. Plug the threaded rod on the X motor end to the left coupling on the left bottom of the Z axis. Then thread the 320mm smooth rod into the linear bearing.

Note: the smooth rods and the threaded rod of Z axis are vertical and the X axis is
horizontal, which is very important, or it will hinder the move of the Z axis.
Step5. Fix the locking rings on the end of the rod if you got the silver rings.

Step5. Now we can connect the wires to the PSU.
1) Mind the color of the wires. The wrong connection of the wire will cause serious damage to the PSU and even to the control board of the printer.
As you can see, there are 7 wires and 7 screws in total. Note the correspondence between the color of wires and the connector.
Brown------L
Blue ------N
Yellow------ GND
Red ------ --+ V
Black------COM

GEEETECH
2) Pay attention to the switch on the right side of the PSU, there are two options of voltage: 110 V and 220V, choose according the standard in your country. As shown in the following picture. Remove the yellow paper; you can use some hard sticks to reach the switch.
