• ? Ventilation: Operate the printer in a well-ventilated area, especially when printing with materials that may produce fumes.
• ? Supervision: Keep the printer and its accessories out of reach of children.
• ⚠️ Modification: Do not modify the printer's electrical components or structure without proper knowledge, as this may lead to hazards.

Printer Components Overview

Familiarize yourself with the main parts of your Anycubic Kobra 2 Max:

• Printer Base: Houses the main control board, power supply, and the heated build platform.
• Gantry Frame: The vertical structure that supports the print head assembly and moves along the Z-axis.
• Print Head Assembly: Contains the extruder motor, hotend, nozzle, cooling fans, and the X-axis linear rail. This assembly moves horizontally (X-axis) to deposit filament.
• Build Plate: A removable, flexible magnetic PEI sheet attached to the heated bed. It provides a good surface for print adhesion and allows for easy print removal.
• Filament Holder: Mounts onto the printer frame to hold the spool of filament.
• Control Screen: A touchscreen interface for operating the printer, adjusting settings, and monitoring prints.
• Extruder: Pushes the filament from the spool through the Bowden tube to the hotend.
• Z-Axis System: Consists of threaded rods and motors that move the gantry up and down.
• X-Axis System: A linear rail and motor that moves the print head assembly left and right.
• Y-Axis System: A linear rail and motor that moves the build plate forward and backward.

Assembly Instructions

Follow these steps to assemble your Kobra 2 Max:

1. Attach Gantry to Base: Align the gantry frame with the mounting points on the printer base. Secure it using the provided screws and Allen wrench. Ensure it is firmly attached and stable.
2. Connect Cables: Connect the necessary cables from the gantry (e.g., stepper motor cables, endstop cables, hotend wiring) to the corresponding ports on the printer base. Refer to the quick start guide for specific port locations. Ensure all connections are secure.
3. Mount Filament Holder: Attach the filament holder assembly to the designated location on the printer frame, typically on the side or top.
4. Install Build Plate: Place the magnetic PEI build plate onto the heated bed. Ensure it is centered and lies flat.
5. Final Checks: Verify all screws are tightened and all cables are properly connected and managed.

First Use and Setup

Prepare your printer for its first print:

1. Power On: Connect the power cable and turn on the printer using the power switch. The control screen should illuminate.
2. Auto-Leveling: Navigate the touchscreen menu to initiate the auto-leveling process. The printer will probe the build surface at multiple points to create a mesh for compensation.
3. Load Filament:
   • Place the filament spool onto the filament holder.
   • Feed the filament end into the extruder inlet.
   • Use the touchscreen controls to preheat the nozzle and extrude filament until it flows smoothly.
4. Wi-Fi Connection (Optional): If your model supports Wi-Fi, follow the on-screen prompts to connect to your network for remote monitoring or file transfer.

Printing Process

Transforming a 3D model into a physical object involves several steps:

1. Slicing Software: Use slicing software (e.g., Anycubic Slicer, Cura) to import your 3D model file (STL, OBJ). Configure print settings such as layer height, infill, print speed, and temperature based on the filament type. The slicer generates a G-code file, which is the printer's instruction set.
2. File Transfer: Transfer the generated G-code file to the printer. This can be done via a USB drive or Wi-Fi connection, depending on your printer's capabilities.
3. Start Print:
   • Select the G-code file from the printer's interface.
   • The printer will preheat the nozzle and bed to the specified temperatures.
   • Once heated, the print will begin.
4. Monitor Print: Observe the first few layers to ensure good adhesion and proper extrusion. Periodically check the print's progress.
5. Remove Print: After the print is complete and the bed has cooled sufficiently, carefully remove the magnetic build plate. Gently flex the plate to detach the printed object. If necessary, use the provided scraper carefully.

Maintenance and Care

Regular maintenance ensures optimal performance and longevity:

• Nozzle Cleaning: After prints, use the cleaning needle to clear any residual filament from the nozzle tip. Periodically perform a "cold pull" if clogs persist.
• Build Plate Cleaning: Wipe the PEI sheet with isopropyl alcohol (IPA) and a clean cloth before each print for best adhesion. Avoid touching the surface with bare hands.
• Lubrication: Apply lubricant (e.g., white lithium grease) to the Z-axis rods and linear rails periodically to ensure smooth movement.
• Belt Tension: Check the tension of the X and Y-axis belts. They should be snug but not overly tight. Adjust as needed using the tensioning screws.
• Firmware Updates: Visit the Anycubic website for the latest firmware updates to improve performance and add features. Follow the update instructions carefully.

Troubleshooting Common Issues

Address common printing problems with these solutions:

• Print Not Sticking to Bed (Adhesion): Ensure the bed is clean and level. Adjust Z-offset for optimal first layer squish. Consider using a brim or raft in your slicer settings.
• Stringing or Oozing: Reduce retraction distance and speed in slicer settings. Ensure filament is dry. Lower printing temperature slightly.
• Under-Extrusion: Check for nozzle clogs. Verify filament path is clear. Calibrate E-steps for the extruder. Ensure filament diameter setting in slicer is correct.
• Layer Shifting: Check belt tension. Ensure stepper motor drivers are not overheating. Reduce print speed or acceleration.
• Warping: Use a brim or raft. Ensure the heated bed temperature is appropriate for the filament. Consider using an enclosure to maintain ambient temperature.
