Wiring

Check Before Use

1. Pulley elastic adjustment
   Check if the print head is shaking. If it is, adjust the hexagonal isolation column located underneath the print head until it slides smoothly and without shaking.
   Check if the print bed is shaking. If it is, adjust the hexagonal isolation column located underneath the print bed until it slides smoothly and without shaking.

2. Belts
   Please manually move the print head and print platform. If there is any difficulty or abnormal noise during the movement, adjust the tensioner to ensure smooth sliding of the print head or platform.

3. Connecting to Power
   Connect the printer to a power outlet with the power cable, then power on the printer.

Power-on guide

• Note: The current interface is for reference only, Due to ongoing feature upgrades, please refer to the Ul of the latest firmware release for accurate information.

Leveling

Press “Tools” – “Control” – ‘Auto Level”. Wait for the machine to complete the leveling process.

Note:

1. Please check whether the PEl board is installed before leveling.
2. The leveling sensor is only used for platforms with metal surfaces. If you replace the printing platform by yourself,!

please choose a platform with a metal surface to ensure the normal use of the automatic leveling function.

Loading Filament

1. Put the filament onto the spool holder.
2. Insert the filament into the extruder until you feel some resistance. While doing so, press and hold the button on top of the extruder.
3. Press “Tools’ – “Filament” – “PLA/ABS”. Wait for the nozzle to heat up to the preset temperature. Press “Extrude” and wait for the filament material to be extruded from the nozzle. After stopping the filament feed, please clean the nozzle.

First print

1. Select a model from the local or U-DISK and start printing. *We recommend using one of the pre-loaded files as a first test print.

Other Function Descriptions

Vibration Compensation: It is recommended to perform a resonance detection when the printing time exceeds 300 hours or after the machine has been moved, in order to achieve better printing results. Resonance detection helps identify any resonance or vibration issues that may occur during the printing process, and allows appropriate measures to be taken to mitigate their impact. Regular resonance detection helps maintain the stability and accuracy of the printer, improving printing quality.
Press “Tools” – “Control” – “Vibration Compensation” and wait for the machine to complete the calibration. Please do not
touch the machine during the calibration process. Filament Runout Detection: This function is designed to prevent printing failures when the filament runs out during the middle of a print. It alerts the user to replace the filament before continuing the print, effectively preventing wasted prints due to filament shortage.
Note: After filament runout, you will need to remove the remaining filament from the filament tube and then insert a new filament. Retraction Instructions:Press “Tools” – “Filament” – “PLA/ABS”. Wait for the nozzle to heat up to the preset temperature. Press “Retract and wait for the filament material to retract, or manually pull out the filament directly by pressing the button above the extruder.

Maintenance Recommendation

2-axis Lead Screws

*The Z-axis lead screw needs regular lubrication, as proper lubrication ensures smooth movement. It is recommended to perform maintenance every three months. Before applying lubricating grease to the Z-axis lead screws, it is important to clean them thoroughly, removing any dust or plastic particles. Then, using the axis mavement controls, move the print head to a higher position. Apply a thin coat of lubricating grease on the 2-axis lead screws, and then home the printer again. You can repeat this movement process a few times to ensure the grease is evenly distributed over the Z-axis lead screws. Once completed, clean off any excess lubricating grease that may have accumulated near the leadscrew nuts.

X/Y-axis double metal spindles

*The X/Y-axis double metal spindles require regular lubrication, as proper lubrication ensures smooth movement.it is recommended to perform maintenance ance a month. Before applying lubricating grease to the X/Y-axis double metal spindles, it is important to clean them thoroughly, removing any dust or plastic particles. Then, apply a thin coat of lubricating grease on the X/Y-axis double metal spindles and home the printer. You can repeat the movement process a few times to ensure the grease is evenly spread over the X/Y-axis double metal spindles.

Troubleshooting Guide

If there is a leveling anomaly, please follow the steps below to check:

1. After powering off, check the wiring of the leveling calibration module to ensure it is connected properly. Then, restart the machine.
2. Press (Tools]-[Control]-[Module Calibration)-(Position Calibration]. Use the [X Move) and [Y Move] options on the screen to move the nozzle to the center point of the calibration module. Once done, click on [Save]. Afterward, perform the leveling operation again.

X/Y/Z axis motor not moving or making abnormal noise:

1. Check if the motor wires are loose and recheck the connections.
2. The corresponding limit switch may not be triggering properly. Check if there is any interference with the axis movement and ensure that the limit switch wires are secure.

Extruder abnormal extrusion:

1. Check if the extruder motor wire is loose.
2. Ensure that the extruder gear is securely tightened to the motor shaft.
3. The print head may not be getting sufficient cooling. Make sure that the print head cooling fan is functioning properly.
4. There may be a clog at the nozzle. Try briefly heating the nozzle to 230°C and manually extruding the filament with force to clear the clog.
   Alternatively, use a fine needle to clear the nozzle while it is preheated.

Model not sticking to the platform or warping:

• The key to model adhesion to the platform is whether the filament attaches to the platform during the first layer. If the distance between the nozzle and the platform exceeds 0.2mm during the first layer, adhesion to the platform will be significantly reduced, requiring releveling.
• When slicing the model, set the print platform adhesion to “Brim,’ which helps enhance adhesion and prevent warping issues.

Model misalignment:

1. The movement speed or print speed may be too fast. Try reducing the speed.
   • The X/Y axis belts may be too loose, or the timing pulleys may not be securely fixed.

Excessive stringing:

1. Insufficient retraction distance. Increase the retraction distance in the slicing software.
   • Slow retraction speed. Increase the retraction speed in the slicing software.
2. Enable Z-lift during retraction in the slicing software, with a lift height of approximately 0.25mm.
3. The printing temperature may be too high, causing the filament to be excessively viscous. Lower the printing

Attention

1. Anycubic 3D printer generates high temperature. DO NOT reach inside of the printer during operation. Contact with extruded materials may cause burns.
2. Use high temperature-resistant gloves when operating the product.
3. This equipment is not suitable for use in locations where children are likely to be present.
4. The fuse rating for the printer is 250V 10A. Never replace the fuse with one of a higher amperage, otherwise it may cause fire.
5. The socket-outlet shall be easily accessible. If the above problems cannot be solved, please initiate consultation in our after-sales service system, and our engineers will reply you in the form of email within one working day.
