3. Setup Guide

3.1 Unboxing and Initial Assembly

Carefully unpack all components. The printer comes largely pre-assembled. Refer to the included quick setup guide for detailed visual instructions. Ensure all packaging materials, especially the large styrofoam blocks under the print bed and any zip ties, are removed before proceeding.

• Mount the LCD display.
• Connect all necessary cables. Ensure the LCD cable and motor cables are properly routed and connected.
• Secure the 4 main bolts as indicated in the quick setup guide.

3.2 Power Connection and Voltage Setting

Before powering on, verify the voltage switch on the back of the unit is set correctly for your region (e.g., 115V for USA, 220V for other regions). Incorrect voltage setting can prevent the printer from operating correctly.

3.3 Automatic Leveling

The Anycubic Kobra S1 Combo features automatic bed leveling. Follow the on-screen prompts on the LCD display to initiate the auto-leveling process. This ensures optimal first layer adhesion and print quality.

4. Operating Instructions

4.1 Filament Loading

Insert the filament into the designated guide. Use the "Filament In" function on the LCD screen to automatically feed the filament through the hotend until it extrudes smoothly.

4.2 Preparing Print Files (Slicing)

The printer requires G-code files for printing. Use a compatible slicing software (e.g., Cura, often provided on the included SD card or downloadable from the manufacturer's website) to convert 3D models (.stl files) into G-code. Ensure the latest version of the slicing software is used for best results.

• Load your .stl model into the slicing software.
• Configure print settings (layer height, infill, supports, etc.).
• Slice the model to generate the .gcode file.
• Copy the .gcode file to the root directory of the SD card for the printer to recognize it.

4.3 Starting a Print

Insert the SD card into the printer. Navigate the LCD menu to select your desired .gcode file and press "Print". The printer will preheat and begin the printing process.

4.4 Remote Control via Anycubic App

Utilize the Anycubic App for remote control and monitoring of your printer. This allows you to start prints, check status, and even record time-lapse videos of your prints from your mobile device.

5. Maintenance

5.1 Filament Drying

Proper filament storage and drying are crucial for print quality. The Anycubic ACE Pro unit provides efficient drying. Always store unused filament in a dry environment.

5.2 Hotend Maintenance

The tools-free hotend disassembly design simplifies maintenance. Regularly inspect the hotend for clogs or wear. Replacement hotends are available from Anycubic.

5.3 Firmware Updates

Regularly check for and install firmware updates to ensure your printer operates with the latest features and improvements. Updates can often be performed via Wi-Fi (OTA Update) or by downloading the firmware to an SD card.

6. Troubleshooting

6.1 Common Printing Issues

• "Spaghetti" Detection: The AI monitoring system will alert you to filament tangles or print failures resembling spaghetti. Pause the print, clear the issue, and resume if possible.
• Print Not Starting / Black Screen: Verify the voltage switch on the back of the printer is set correctly for your region (e.g., 115V or 220V). An incorrect setting can cause the screen to go black when attempting to print. Power off, adjust the switch, and restart.
• Filament Unloading Issues: If filament has a bulge at the end, it may be difficult to unload. Gently pull the filament while heating the hotend, or refer to the detailed manual for extruder disassembly if necessary.
• Poor Adhesion: Ensure the print bed is clean and properly leveled. Adjusting bed temperature or using an adhesive may improve adhesion.
