3. Setup Guide
Follow these steps to set up your ANYCUBIC Kobra S1 3D printer for the first time.
3.1 Unboxing and Initial Preparation
Carefully remove the printer and all accessories from the packaging. Ensure all components listed in the packing list are present.
Video 3.1: ANYCUBIC Kobra S1 Unboxing and Setup Guide. This video demonstrates the initial unboxing, removal of protective materials, and installation of basic components.
3.2 Unlock Print Head
Before operation, unlock the print head by cutting the zip ties and removing the cardboard protection that secures it during shipping.
Figure 3.1: The image shows the print head secured with cardboard and zip ties. These must be carefully removed before use to allow the print head to move freely.
3.3 Unlock Hot Bed
Remove any protective foam or securing elements from the hot bed area to allow for proper movement and prevent damage during operation.

3.4 Spool Holder Installation
Attach the filament spool holder to the designated slot on the printer's rear panel using the provided screws and Allen key. This ensures stable filament feeding.

3.5 Power Connection
Connect the power cord to the printer's power input and then to a suitable power outlet. Ensure the power switch is in the OFF position before connecting the power cord.
3.6 Activated Carbon Filter Installation
Install the activated carbon filter into its designated compartment inside the printer. This filter helps to reduce odors and fumes produced during the printing process.

Note: After completing the installation, power on the machine and follow the on-screen boot options to finalize the setup before starting your first print.
4. Operating Instructions
4.1 Automatic Bed Leveling (LeviQ3.0)
The Kobra S1 features LeviQ3.0 automatic bed leveling. Access this function through the touchscreen interface to ensure optimal first layer adhesion. This process is quick and requires minimal user intervention, making it easy for beginners.

4.2 Loading Filament
Insert the chosen filament into the filament sensor and feed it into the extruder until it is properly loaded. The printer supports various filament types including ABS, ASA, PLA, PETG, and PLA+.

Note: When printing TPU, it is only supported by the standalone printer and cannot be used with Anycubic ACE Pro.
4.3 Printing via Anycubic APP and Makeronline
The Anycubic APP allows for remote monitoring and control of your prints. You can view real-time progress, record time-lapses, and access a library of high-quality models from Anycubic Makeronline.

5.2 Cleaning and General Care
- Regularly clean the print bed with isopropyl alcohol to ensure good adhesion.
- Inspect the extruder nozzle for clogs and clean as needed using the provided nozzle cleaner.
- Keep the printer's interior free of dust and filament debris.
- Check belt tension periodically; the printer includes belt tension monitoring.
6. Troubleshooting
6.1 Common Printing Issues
- Poor First Layer Adhesion: Re-run LeviQ3.0 auto-leveling. Ensure the print bed is clean and free of grease. Adjust Z-offset if necessary.
- Filament Clogging: Check the hotend temperature for the specific filament. Use the nozzle cleaner to clear any blockages. Ensure filament is properly loaded.
- "Spaghetti" Failures: The AI monitoring system will detect and alert you to these anomalies. Check for proper bed adhesion and filament flow.
- Layer Shifting: Verify that the printer is on a stable surface. Check belt tension and ensure all mechanical components are secure.
6.2 Firmware Updates
It is recommended to update the printer's firmware to the latest version (e.g., 2.4.8.3 or newer) to access new features and improvements. You can update via Wi-Fi (OTA Upgrade) or by downloading the firmware from the Anycubic website and installing it via USB.
