About the ET4 Pro 3D Printer

The ET4 Pro 3D Printer is designed for DIY enthusiasts. Some parts require assembly by the customer. It is recommended to secure connections with hot glue or silica gel. Please follow the instructions carefully to avoid injuries or damage.

Important Safety Precautions

• Keep the printer away from heat sources, fire, flammable, and explosive materials. Place it in a ventilated, cool, and dust-free environment.
• Do not place the printer on unstable surfaces, as vibration can affect print quality.
• Use only the original power cord supplied with the printer. The working power supply is 110V/220V AC. Ensure the power plug is connected to a three-hole socket with a ground wire to prevent electrical hazards.
• Do not touch the nozzle, extruder, or heating bed while the printer is operating to prevent burns.
• Avoid wearing gloves or bracelets when operating the machine to prevent entanglement with moving parts.
• After printing, clean material residues with tools while the nozzle is still warm. Do not touch the nozzle with bare hands during cleaning.
• Regular maintenance is crucial for good condition and high-quality prints. Turn off and cool down the printer before any repair. Use a dry cloth to wipe away dust and debris. Lubricate sliding parts, screw rods, and bearing parts with grease.
• This printer is not intended for use by children under 14 or individuals over 60 without assistance and guidance.
• Self-disassembly or modification may lead to damage, abnormal performance, and void the warranty.
• Always cut off the power supply after use.

Assembly Guide

Step 1: Assemble the Gantry

This step involves assembling the main frame structure of the printer. It shows the vertical frame components being connected to form the printer's base and uprights. The X-axis assembly, which houses the print head, is then mounted onto the horizontal rail of the gantry. The diagram indicates four connection points (x4) for this assembly. Close-up views illustrate the X-axis rail and how the assembly moves along it, along with the associated X-axis motor.

Step 2: Install the Timing Belt

This step details the installation of the timing belt. A coiled belt (labeled '2') is shown. The belt needs to be routed correctly around the pulleys located on the X-axis assembly and the printer frame. An arrow indicates the need to 'Tighten' the belt. Close-up images demonstrate the proper attachment of the belt to the carriage and the motor pulley. A visual comparison shows an incorrect installation (marked with a red 'X' symbol) versus a correct installation (marked with a green checkmark symbol).

Step 3: Mount Components and Connect Wiring

This step focuses on mounting various electronic and mechanical components onto the main printer frame and connecting their wiring. A diagram lists key components such as S-Z, BL, TMP, FAN, E-M, S-M, and X-M, showing their placement on the frame. The overall printer structure is depicted with the X-axis and Z-axis assemblies in place. Close-up views highlight the extruder assembly, the print bed, and the Z-axis motor. A wrench (labeled '8') is shown with a nut, indicating the need for fastening components.

Step 4: Install Filament Holder and Extruder

This step covers the installation of the filament spool holder and the extruder assembly. The filament spool holder (labeled '5') is attached to the top of the printer frame using three screws (x3). The extruder motor and its associated assembly (labeled '4') are shown being mounted onto the X-axis carriage. Components labeled '3', '6', and '7' are depicted with quantities (x2 each), likely representing screws or brackets used for these attachments.
