How to Assemble the Ender 3 V2 3D Printer: A Complete Walkthrough
Ender 3 V2 is an upgraded version of the popular Ender 3 Pro 3D printer. It offers several improvements over the original Ender 3, including a larger build volume and a more powerful main board. It also has improved motion control and a resume print function that allows the printer to pick up where it left off after a power outage.
Assembling the Ender 3 V2 is a simple process that requires minimal tools and no prior 3D printing experience. To start the assembly process, you can follow these simple steps.

Step 1: Unbox the 3D Printer
Carefully remove the packaging materials and ensure you have all the parts and pieces that came with the printer. You should have:
All set? Let’s proceed.

Step 2: Installing the Z-Axis Switch and Z-Axis Profile
Get the limit sensor, install it to the z-axis profile, and lock them using the 4 M5X45 screws and the spring washers to ensure that it’s tightly fixed.
Take the z-axis profile and attach it to your 3D printer. Ensure that the profile and the limit switch sensor are at the same height.

Take the second z-axis profile and lock it to the right-hand section of the printer using the two m4X18 screws.
Step 3: Install the Z-Axis Motor Kit
The Z-axis motor kit comprises the Z-axis motor and a thin white metal rod. To start assembling, loosen the screws on the motor to create space for the motor rod to pass through. Then insert the metal rod and tighten it using the screws shown below.
Ensure that you align the Z-axis motor kit with the Z-axis profile.

Step 4: Install the Pneumatic Connector to the XE Kit
Take the pneumatic connector and tighten it to the XE using an open-end wrench. Then, use the two M4X16 screws to fit the XE shaft to the X-axis profile, as shown below.
Next, insert the timing belt through the XE shaft.

Just ensure that you insert it using the right direction.
Step 5: Assembling the Nozzle Kit
Take the already installed pneumatic connector and XE kit, insert the nozzle from one of its ends, and move it almost towards the end.
Next, take the Z-axis passive block and attach it to the X-axis profile.
Use M4X16 screws with spring washers to lock and tighten the Z-axis passive block.
Step 6: Install X-Axis Tightener
Start by inserting the timing belt into the tightening block and then put both of them into the X-axis tightener.
Tighten the plastic thumb nut and use the M4X16 screw to tighten them to the Z-axis passive block.
Once done, take the installed z-axis moving module to your printer. Adjust the tightness of the X and Y axis to ensure that it’s moving smoothly.
Just ensure that it does not fall off on its own.
Step 7: Install the Gantry Profile and Screen
Take the four M5x25 head cap screws with washers to fix the gantry to the top of the profiles.
Next, take the screen and install it on your 3D printer. Use a hexagon socket wrench to lock the screws to the display module.
Just verify that the screen is aligned correctly with the front profile.
Next, take the filament spool holder and install it to the upper profile of the gantry, as shown below.
The filament spool holder helps you be organized during 3D printing.
Step 8: Connect the Bowden Tube and Rotary Knob to the Extruder
As shown below, insert the Bowden tube into the extruder until it goes no further.
Next, take the rotary knob to the top of the extruder motor shaft. Push the covers of the profile on both sides to the top.
Step 9: Install Electrical Connections
Take the X, E, and Z-axis stepper motors and connect them based on the yellow labels on the connectors.
Next, connect the X and Z axis switches based on the yellow labels.
Ensure that the plugs and sockets are correctly aligned. Once done, set the correct voltage.
Next, plug in the power source.
Turn on the switch, and you should see the screen turning on.
Step 10: Level the Bed
On the screen section, go toPrint > Auto home.You will see the bed and the pneumatic connector kit moving. Once it stops moving, selectDisable Stepperon the screen.
Next, you will need to use a piece of paper tolevel the 3D printer bed. You can insert the paper between the bed and the nozzle. Adjust the nuts below the bed in each corner of your printer until the paper is scratched slightly.
Next, go toPrepare > Preheat PLAand wait until the temperature matches the one shown on the screen. you may theninsert the card with your G-code.
Step 11: Loading the Filament
Once you assemble all the parts, you must load the filament appropriately into your Ender 3 V2 3D Printer. There aredifferent 3D printer filaments available, and you should buy the one specific to your nozzle. Before loading your filament, prepare it properly. Take the end of the filament and cut it at a 45-degree angle.
Next, insert the filament and ensure it goes into the right hole. Push it in until it stops, and make sure that it is secure and not coming out. Use the knob to move the filament until you no longer see it moving.
Now that you have fed the filament, it’s time to check the results. Ensure that the filament comes out of the nozzle correctly and extrudes correctly. If everything looks good, you’re ready to start 3D printing!
Enjoy a Perfectly Assembled Ender 3 V2
Assembling the Ender 3 V2 is a relatively straightforward process that you can finish in less than an hour as most of the parts are assembled already, unlike other 3D printers like Anet A8, where users have to assemble everything from the ground up.
Just take your time and follow the instructions carefully. There are a lot of small parts, and it can be easy to miss a step or two. Use the correct screws in each section, and ensure that the voltage used is right, as the wrong voltage can affect the power supply.
If your 3D printer bed is not correctly leveled, you’ve got a problem.
