2. Safety Information
Please read and understand all safety warnings before operating the printer. Failure to do so may result in injury or damage to the printer.
- Resin Handling: Resin is a chemical irritant. Always wear appropriate personal protective equipment (PPE), including gloves and safety glasses, when handling liquid resin or uncured prints. Work in a well-ventilated area.
- UV Light Exposure: The printer uses powerful UV light. Never look directly at the UV light source. The printer cover is designed to block UV light during operation.
- Electrical Safety: Ensure the printer is connected to a grounded power outlet. Do not operate with wet hands or in damp conditions. Disconnect power before performing any maintenance or cleaning.
- Moving Parts: Keep hands and loose clothing clear of moving parts during operation.
- Disposal: Dispose of uncured resin and contaminated materials according to local regulations. Cured resin can be disposed of as regular plastic waste.

4. Setup
4.1 Initial Placement
Place the printer on a stable, level surface away from direct sunlight and heat sources. Ensure adequate ventilation around the printer.
4.2 Power Connection
Connect the power adapter to the printer and then to a grounded electrical outlet.
4.3 Resin Vat and Build Plate Installation
Carefully install the resin vat onto the printer platform, ensuring it is securely seated. Attach the build plate to the Z-axis arm. The Photon Mono M5s features a leveling-free system, eliminating the need for manual calibration of the build plate.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your printer.
6.1 Cleaning the Resin Vat and Build Plate
- After each print, carefully remove the build plate and clean off any excess resin using isopropyl alcohol (IPA).
- If changing resin types or storing the printer, clean the resin vat thoroughly with IPA. Ensure no cured resin particles remain on the FEP film.

6.2 Replacing Components
Over time, certain components may require replacement due to wear or damage.
- FEP Film: The FEP film in the resin vat is a consumable part. Replace it if you notice cloudiness, scratches, or punctures.
- LCD Screen: If the LCD screen is damaged or shows dead pixels, it will need to be replaced.
- Build Plate: The build plate may need replacement if it becomes severely damaged or warped.
- Motherboard: In rare cases of electronic malfunction, the motherboard may need replacement.
- Lead Screw Motor: If the Z-axis movement becomes erratic or stops, the lead screw motor might need attention.

7. Troubleshooting
This section addresses common issues you might encounter during operation.
- Print Failure (Bottoming-out): The printer's intelligent print status detection can report and analyze common bottoming-out failures, providing suggestions for improvement. Ensure proper support placement and exposure settings.
- Model Not Sticking to Build Plate: Ensure the build plate is clean and free of resin residue. Verify that the initial layer exposure time is sufficient in your slicing software.
- Resin Not Curing: Check the UV light source for proper function. Ensure the resin is not expired and is stored correctly. Verify exposure settings in the slicing software.
- Printer Not Responding: Check power connections. Restart the printer. If issues persist, refer to the official Anycubic support resources.
