¶ Step 1: Install the printer
After you receive the printer, please refer to the following instructions and unboxing video to install the printer and complete the printing preparation.
Kobra 2 Neo:
Kobra 2 Pro:
Kobra 2 Plus:
Kobra 2 Max:
¶ Step 2: Enter the user boot process
After the installation is complete, please power on the printer. The printer will enter the boot process and then follow the prompts to complete the Settings.
Then click "Tools" - "Control" - "Auto-Level" on the display screen and wait for the machine to finish automatic leveling.
Note: The leveling sensor is only used on the metal surface of the printing platform, please check whether the spring steel is installed before leveling.
¶ Step 3: First extrude the filament
Place the filaments on the stand and insert them into the extruder while holding down the button at the top of the extruder until some resistance is felt. Then click "Tools" - "Extrude" - "PLA" from the display screen, wait until the nozzle heats to the preset temperature, click "Extrude" and wait for the filaments to extrude from the nozzle.
Note: Straighten the end of the filaments before inserting them into the extruder.
¶ Step 4: First printing
After checking the extrusion effect, it is recommended to use one of the pre-installed files as the first test print.
Note: After you start the printing process, please observe the first layer. If something like the following occurs, the Z-Offset does not match. You can adjust the Z-Offset during the printing process to adjust the distance between the print head and the printing platform.
¶ Step 5: Model slicing and printing
After the first printing, please download the Anycubic Slicer Next Slicing software from the following page, then follow the software instructions to import the model and complete the slicing. Once the slicing is complete, you can save the gcode file to a USB flash drive and insert it into the printer for printing.
Note: When you switch filaments from different manufacturers, it is recommended that you calibrate parameters such as temperature and extrusion flow before slicing and printing.

¶ 1. Common Problems:
¶ FAQ
If you have questions about the parameters or functions of the machine when printing, please browse the documentation below for answers.
¶ The print head fails to heat up
If the printer shows a heating failure when heating the nozzle, it may be due to poor cable contact or hardware fault. Please follow the following documents to rectify the fault.
Kobra 2 Neo- Print head fails to heat up
Kobra 2 Pro- Print head fails to heat up
Kobra 2 Plus- Print head fails to heat up
Kobra 2 Max- Print head fails to heat up
¶ The print head NTC is abnormal
If the printer indicates that the NTC of the print head is abnormal when heating the nozzle, the NTC cable of the print head may be loose or the hardware is faulty. Please refer to the following documents for troubleshooting.
Kobra 2 Neo- Print head NTC exception
Kobra 2 Pro- Print head NTC exception
Kobra 2 Plus- Print head NTC exception
Kobra 2 Max- Print head NTC exception
¶ Hot bed heating failed
If the printer indicates a heating failure when heating the hot bed, reinsert the hot bed cable or measure the voltage of the port on the mainboard.
Kobra 2 Neo- Hot bed heating failure
Kobra 2 Pro- Hot bed heating failure
Kobra 2 Plus- Hot bed heating failure
Kobra 2 Max- Hot bed heating failure
¶ The hot bed NTC is abnormal
If the printer indicates that the NTC of the hot bed is abnormal when heating the hot bed, reinsert the hot bed wire or measure the resistance of the hot bed NTC wire. You can rectify the fault according to the following documents.
Kobra 2 Neo- Hot bed NTC anomaly
Kobra 2 Pro- Hot bed NTC anomaly
Kobra 2 Plus- Hot bed NTC anomaly
Kobra 2 Max- Hot bed NTC anomaly
¶ Module calibration exception
Kobra 2 Neo- Module calibration exception
Kobra 2 Pro- Module calibration exception
Kobra 2 Plus- Module calibration exception
Kobra 2 Max- Module calibration exception
¶ 2. Print effect problem:
¶ Model drawing
The model is drawn because of excessive discharge from the nozzle during nozzle movement. Please follow the method below to improve the model drawing problem.
(1) Modify the printing parameters: the model has a long empty driving distance, which leads to the outflow of consumables from the nozzle during the empty driving process, so when printing multiple models, it is recommended to reduce the model spacing and increase the pumping length and pumping speed, and reduce the printing temperature.
(2) Drying consumables: the consumables are damp, and the water vaporization in the consumables during printing leads to abnormal flow of consumables, so it is recommended to dry the consumables first, and then level the printing.
(3) Check the nozzle: If the wrong nozzle configuration is selected during slicing, there will be too many supplies flowing out of the nozzle during printing, so ensure that the nozzle configuration is consistent with the actual nozzle specifications before printing. In addition, please check whether the nozzle is worn due to long-term use and needs to be replaced with a new nozzle.
¶ Model warping
When the model is curled or falls off the hot bed when printing, please use detergent to clean the printing board, increase the temperature of the hot bed, reduce the speed of the cooling fan, it is best to open the Brim, increase the width of the Brim, and then level the printing. In addition, the model of thin and tall pieces is recommended to use tree support, and you can also change the placement method or cut the model after printing.
¶ Model misalignment
If the model has regular misalignment during printing, please adjust the tightness of the synchronization belt first, and then perform vibration compensation to reduce the printing speed before printing the local test model.
¶ Resonance patterns appear in the model
The resonance pattern of the model is caused by the natural frequency oscillation caused by the print head or the hot bed emergency stop and emergency start. Please check the setting of the adding speed and speed of the slice first. Then adjust the tightness of the synchronization belt and check the tightness of the print head bracket and the hot bed bracket.
¶ Model gloss effect layering
At the same printing temperature, the lower the printing speed, the brighter and smoother the surface; At the same printing speed, the higher the printing temperature, the brighter and smoother the surface. The essence is that the degree of material melting is different, resulting in the surface roughness of the printed part is different, and this phenomenon is more obvious when printing on silk consumables. It is recommended to replace a larger printing layer when slicing, appropriately reduce the printing speed and increase the printing temperature.
