Check Before Use

Pulley elastic adjustment

ANYCUBIC-Kobra-2-Neo-3D-Printer-FIG-11

  • 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.ANYCUBIC-Kobra-2-Neo-3D-Printer-FIG-12
  • 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.

Belts

ANYCUBIC-Kobra-2-Neo-3D-Printer-FIG-13

  • 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.

Power On

  • Connect the printer to a power outlet with the power cable, then power on the printer.

Note: When inserting the power cord, please avoid the print head cable to prevent any interference issues.

Screen Interface Overview

ANYCUBIC-Kobra-2-Neo-3D-Printer-FIG-15

Note: The current interface is for reference only. Due to the continuousupgrading of functions, it shall be subject to the latest firmware Ulpublished on the official website.

Leveling

ANYCUBIC-Kobra-2-Neo-3D-Printer-FIG-16

  • In the settings page, select [Auto level] and 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.
  3. This PEl sheet can be used for printing on both sides, but you need to follow the following rules: If you level the bed using side A, then you should also print on side A. If you switch to side B, you will need to re-level the bed.

Loading Filament

ANYCUBIC-Kobra-2-Neo-3D-Printer-FIG-17

  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. In the settings page, select [Filament] – [Extrude], and wait for the nozzle to heat up to the preset temperature. The filament will be automatically extruded.ANYCUBIC-Kobra-2-Neo-3D-Printer-FIG-18
  4. Wait for the filament to extrude from the nozzle.
  5. Select [Stop] to end the filament loading process.
  6. Clean the melted filament off the nozzle.

Retraction Instructions

ANYCUBIC-Kobra-2-Neo-3D-Printer-FIG-19

In the settings page, select [Filament] – [Retract]. Wait for the nozzle to heat up to the preset temperature, and the filament will automatically retract. Press the button on the top of the extruder and pull out the filament.

WARNING: During the printing process, filament replacement can only be done manually, and retracting or extruding filament cannot be performed.

Start printing

  1. Insert the TF card into the printer’s card slot.ANYCUBIC-Kobra-2-Neo-3D-Printer-FIG-21
  2. Select the corresponding model and start printing.

Note: After starting the printing process, please observe the situation of the first layer. If situations 1 and 3 occur on the first layer, it indicates that the Z-Offset value is not matchina. You can adiust the Z-Offset value during the printing process to adiust the distance between the print head and the print platform.

Model Resume Function Description

Power Loss Resume

In the event of a sudden power outage or accidentally turning off the machine, this function does not require manual setup. Simply reconnect the power and turn on the machine. You can then resume the print. The PEl platform adheres better when heated. However, if the power loss is too long, the platform will cool down, and the model may detach, making it impossible to resume the print.

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.

Warning

  1. This function requires the purchase of a filament runout detection sensor and its installation to be effective.
  2. After filament runout, you will need to remove the remaining filament from the filament tube and then insert a new filament

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.ANYCUBIC-Kobra-2-Neo-3D-Printer-FIG-25
  2. Select [Module Calibration] in the settings page, then choose [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

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