User Instruction

In order to prevent damage to you and others during use, please be aware of the following:

Please do not attempt to use the machine in any way undescribed in the instructions to avoid accidental personal injury and property damage.
Please do not place this machine near inflammable and explosive materials or high heat sources. Place this machine in a ventilated, cool, and dust-free environment.
Please do not place the printer on a large vibrating or other unstable platform. The shaking of the machine will affect the printing quality.
Please do not replace the power line of other products during installation. Use the original power line supplied with the machine. The working power supply uses 110V/220V AC. The power plug must be plugged into the three-hole socket with a ground wire to avoid damage to components or accidents such as fire and electric shock.
Please do not touch the nozzle and heating bed while the printer is working to prevent high temperature burns and personal injury.
Please do not wear gloves or wrappers when operating the machine in case the movable parts cause entanglement and cutting damage to the human body.
After printing, use the remaining temperature of the nozzle to clean up the filament with the help of tools. Do not touch the nozzle directly with your hands during cleaning to prevent scalding.
Regularly maintain the product. When the power is off, clean the printer body with a dry cloth to wipe away dust and bonded printing materials, foreign objects on guide rails. Lubricating oil is recommended for sliding parts, screw rods, and bearing parts.
Children under 14 years old or people above 60 years old should use this machine under adult supervision to avoid personal injury.
Some filaments will produce a slight odor, but it won't make people feel uncomfortable. It is recommended to use the A8 Plus in a well-ventilated environment.

Quick Operation Guide (More details please check the TF card)

Operating Interface Introduction

First Print

Leveling

Turn to zero: Main Menu “Position” → “Auto home”
Turn off Step Motor: After turning to zero, main menu “Quick Settings” → “Disable stepper”
Leveling: Adjust the distance between the nozzle and the hotbed to 0.1mm.

Filament Installation (take PLA for example)

Preheating: Main Menu “Quick Settings” → “Preheat PLA”. Enter preheating state.
Install Filament: When the preheating temperature reaches the setting data, push the filament into the tube as below. Installation is successful if the material overflows from the nozzle. (Also need to preheat the nozzle when pulling out the filament from the extruder.)
The thumb presses the screw head of the extrusion head, and the index finger holds the air guide. Quickly push the consumables down until the nozzles are spitting out.

Print Operation

Choose Print File: Main Menu “SD Card” → “Print file” → “Model File” Confirm. After the extruder and hot bed reach the setting temperature, the extruder starts moving and prints.

Troubleshooting

Here are some common problems and solutions for the A-Net 3D Printer A8:

Problem: Poor print quality
Solution: Check the nozzle for blockages, ensure the print bed is level, and use high-quality filament.
Problem: Warping
Solution: Increase the print bed temperature, use a brim or raft, and ensure the print bed is clean and level.
Problem: Adhesion issues
Solution: Increase the print bed temperature, use a brim or raft, and ensure the print bed is clean and level.
