2. Safety Information
WARNING: Failure to follow these safety instructions may result in fire, electric shock, injury, or damage to the product or property.
- Hot Surfaces: The extruder nozzle and print bed can reach high temperatures during operation. Avoid touching these components while the printer is active or immediately after use. Allow sufficient time for cooling.
- Moving Parts: The printer contains moving parts that can cause injury. Keep hands, hair, and loose clothing clear of the print area during operation.
- Ventilation: Operate the 3D printer in a well-ventilated area to dissipate any fumes produced during the printing process.
- Power Supply: Use only the provided AC adapter. Ensure the power supply is connected to a grounded outlet. Disconnect power before performing any maintenance or cleaning.
- Filament Handling: Store filament in a dry environment to prevent moisture absorption, which can affect print quality.
- Children and Pets: Keep the printer out of reach of children and pets. Adult supervision is required if children are operating the device.

4. Setup
- Unpacking: Carefully remove the printer and all accessories from the packaging. Retain the packaging for future transport or storage.
- Placement: Place the printer on a stable, level surface in a well-ventilated area, away from direct sunlight, heat sources, or excessive dust.
- Power Connection: Connect the AC adapter to the printer's power input and then plug it into a suitable electrical outlet.
- Filament Loading:
- Place the filament spool onto the filament holder.
- Feed the filament into the extruder's input hole until it is gripped by the feeder mechanism.
- From the printer's menu, select "Load Filament" and follow the on-screen prompts to heat the nozzle and extrude filament until it flows smoothly.
- Auto-Leveling: The MP Cadet features full auto-leveling. Upon initial power-on or when prompted, the printer will automatically calibrate the print bed. No manual adjustments are typically required.
- Software Installation: Install the recommended slicing software (e.g., Cura) on your computer. This software converts 3D models into printable G-code files.
- Wi-Fi Setup (Optional): Refer to the printer's on-screen menu or the online guide (accessible via QR code on the printer) for instructions on connecting the printer to your Wi-Fi network and using the mobile app for printing.

5. Operating Instructions
- Preparing a Model:
- Obtain a 3D model file (e.g., .STL, .OBJ).
- Open the model in your slicing software.
- Adjust print settings (layer height, infill, supports, adhesion) as needed.
- Slice the model to generate a G-code file and save it to the microSD card.
- Starting a Print (MicroSD Card):
- Insert the microSD card into the printer's card slot.
- Navigate the printer's menu using the rotary knob and LCD screen.
- Select "Print from SD" and choose your desired G-code file.
- The printer will begin heating and then start the print.
- Starting a Print (Wi-Fi):
- Ensure the printer is connected to your Wi-Fi network.
- Use the mobile app or compatible software to send the G-code file to the printer.
- Monitor the print status through the app.
- Monitoring and Pausing:
- Observe the print progress.
- To pause a print, select "Pause" from the printer's menu. To resume, select "Resume".
- Removing a Print:
- Once the print is complete and the print bed has cooled, carefully remove the magnetic print bed.
- Flex the print bed to detach the printed object. Avoid using excessive force or sharp tools that could damage the bed.

6. Maintenance
- Cleaning the Print Bed: After each print, ensure the print bed is clean. Use a soft cloth and isopropyl alcohol to remove any residue.
- Nozzle Cleaning: If extrusion issues occur, the nozzle may be partially clogged. Heat the nozzle and gently push a thin needle or cleaning filament through the nozzle opening. For severe clogs, nozzle replacement may be necessary.
- General Cleaning: Periodically clean the exterior of the printer with a dry, soft cloth. Avoid using abrasive cleaners or solvents.
- Firmware Updates: Check the Monoprice website for any available firmware updates. Follow the provided instructions carefully for installation.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Print not sticking to bed | Dirty print bed, incorrect bed temperature (if applicable), insufficient bed adhesion. | Clean the print bed with isopropyl alcohol. Ensure the auto-leveling process completed successfully. Apply a thin layer of glue stick if necessary. |
| Poor print quality (e.g., stringing, gaps) | Incorrect print settings (temperature, retraction), partially clogged nozzle, moist filament. | Adjust print settings in slicing software. Clean the nozzle. Ensure filament is stored in a dry environment. |
| Filament not extruding | Clogged nozzle, tangled filament, incorrect loading. | Clean or replace the nozzle. Check filament path for tangles. Re-load filament according to instructions. |
| Wi-Fi connection issues | Incorrect network credentials, printer out of range, network interference. | Verify Wi-Fi password. Move printer closer to router. Restart printer and router. |
| Printer makes unusual noises | Loose components, obstruction in moving parts. | Inspect the printer for any loose screws or obstructions. Power off and on. If noise persists, contact support. |
