2. Setup and Initial Preparation
2.1 Unboxing and Component Check
Carefully remove all components from the packaging. Refer to the packing list to ensure all items are present and undamaged.
Figure 2: Packing List. This image displays the various components included with the QIDI X-PlusⅡ 3D Printer, such as the printer itself, spare parts box, top cover, side panel, power cord, screwdriver, leveling paper, user guide, USB flash drive, LAN cable, filament holder, random color PLA filament, high temperature extruder, scraper, PEI plate, and solid glue.
2.2 Printer Placement
Place the printer on a stable, level surface in a well-ventilated area, away from direct sunlight, heat sources, and excessive dust. Ensure sufficient space around the printer for operation and maintenance.
2.3 Power Connection
Connect the power cord to the printer and a suitable power outlet. Ensure the power switch is in the OFF position before connecting.
2.4 Software Installation (QIDI Print)
Install the QIDI Print slicer software from the provided USB flash drive or download the latest version from the official QIDI website. This software is essential for preparing your 3D models for printing.

3. Operating Instructions
3.1 Touchscreen Interface
The X-PlusⅡ features a 4.3-inch touchscreen for intuitive control. Navigate through menus for printing, system settings, tools, and service options.

3.2 Extruder Selection and Filament Loading
The printer comes with two types of extruders: a normal dual-gear extruder for common filaments like PLA, ABS, and TPU (max 250℃), and a high-temperature dual-gear extruder for advanced materials such as PC, Nylon, and Carbon Fiber (max 300℃). Ensure the correct extruder is installed for your chosen filament.

To load filament:
- Place the filament spool on the external holder (A) or use the built-in spool holder (B) for internal placement.
- Feed the filament into the extruder until it is gripped by the gears.
- On the touchscreen, select the option to load filament and follow the on-screen prompts.

3.3 Printing Process
Before printing, ensure your 3D model is sliced using QIDI Print software and saved to a USB flash drive.
- Insert the USB flash drive into the printer's USB port.
- On the touchscreen, select "Print" and choose your desired model.
- Confirm print settings and initiate the print.
The printer features a filament runout sensor that will pause the print and alert you if the filament depletes. It also has a resume printing function that automatically saves the breakpoint in case of a power outage, allowing you to continue printing from where it left off.

3.4 Supported Materials
The X-PlusⅡ supports a wide array of materials, enabling diverse printing applications:
- PLA (Polylactic Acid): Common, easy to print, biodegradable.
- ABS (Acrylonitrile Butadiene Styrene): Durable, heat-resistant, requires good ventilation.
- TPU (Thermoplastic Polyurethane): Flexible and elastic.
- Nylon: Strong, durable, and flexible, often used for functional parts.
- Carbon Fiber (PA12-CF): High strength-to-weight ratio, rigid.
- PC (Polycarbonate): Very strong, heat-resistant, and impact-resistant.
- PETG (Polyethylene Terephthalate Glycol-modified): Durable, good layer adhesion, less prone to warping than ABS.

4. Maintenance
4.1 Print Bed Maintenance (Double Sided PEI Plate)
The X-PlusⅡ utilizes a double-sided PEI (Polyetherimide) printing plate, which offers excellent adhesion and helps prevent warping. After printing, allow the plate to cool before removing your print. For stubborn prints, gently flex the plate to release the object. Clean the PEI surface with isopropyl alcohol regularly to maintain adhesion.

4.2 Extruder and Nozzle Cleaning
Regularly inspect the extruder and nozzle for filament residue or clogs. If a clog occurs, refer to the detailed instructions provided on the USB drive or the QIDI official website for proper unclogging procedures. This typically involves heating the nozzle and carefully removing the blockage.
4.3 General Cleaning and Lubrication
Keep the printer clean from dust and debris. Periodically lubricate the Z-axis rods and other moving parts as recommended in the full user guide to ensure smooth operation and prevent wear.
5. Troubleshooting
This section addresses common issues you might encounter during operation. For more complex problems, please contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Filament not extruding / Clogged nozzle | Filament blockage, incorrect temperature, worn nozzle. | Perform a cold pull or hot pull to clear the nozzle. Ensure correct printing temperature for the filament. Replace nozzle if worn. Refer to the user guide for detailed unclogging steps. |
| Poor first layer adhesion | Bed not level, dirty print surface, incorrect Z-offset, wrong bed temperature. | Level the print bed using the leveling paper. Clean the PEI plate with isopropyl alcohol. Adjust Z-offset. Ensure appropriate bed temperature for the filament. Consider using a glue stick for certain materials. |
| Print quality issues (layer shifts, stringing) | Loose belts, incorrect retraction settings, wet filament, printing too fast. | Check and tighten belts. Adjust retraction settings in slicer. Dry filament if it's absorbed moisture. Reduce print speed. |
| Filament runout alert | Filament spool empty or broken. | Replace the filament spool. The printer will pause and allow you to load new filament before resuming. |
| Power outage during print | Unexpected power loss. | The printer automatically saves the breakpoint. Upon power restoration, you will be prompted to resume the print. |
