Read Before Use

Basic Safety and Electrical Requirements

• Verify that the printer’s operating voltage matches the specified requirements to avoid damage or safety hazards. Check the label next to the power socket for specific voltage requirements.
• The printer operates at high temperatures and speeds. Do not allow children or unauthorized personnel to operate the printer to prevent burns, pinching, or other accidents.
• Do not touch the toolhead, heatbed, or motion parts during printing to prevent burns or mechanical injuries.

Operation and Maintenance Recommendations

• To ensure proper functioning of the printer’s internal precision mechanisms, regular maintenance is recommended (see Regular Care and Maintenance).
• To prevent nozzle clogging and achieve better print quality, print TPU filament with the main hotend.
• When printing with the auxiliary hotend, select the supported filament types to avoid issues such as clogging (see Printing Conditions).
• The printer automatically switches between hotends during printing. Do not manually force switching to avoid damaging the device.
• For the best printing results, we recommend using Bambu Lab filaments. These filaments have undergone rigorous compatibility, safety, and stability testing based on the product’s characteristics.
• Unless otherwise specified, always unplug the power cord before any operation, maintenance, or modification to prevent electric shock or equipment damage.
• Unless otherwise specified, allow the printer to fully cool down before any operation, maintenance, or modification.

Safety Instructions for AMS 2 Pro

• To prevent filament feeding jams, do not load flexible materials such as TPU with a hardness of 95A or lower, or moisture-exposed PVA and BVOH into the AMS 2 Pro.
• The AMS 2 Pro supports filament spool widths from 50 mm to 68 mm and diameters from 197 mm to 202 mm. Plastic spools are recommended.
• Connect the printer and a single AMS 2 Pro using the Bambu Bus cable 6-pin to use the AMS 2 Pro drying function. To dry filaments in multiple AMS 2 Pro units at the same time, purchase official Bambu Lab power adapters to supply power to the other AMS 2 Pro units.
• During filament drying, the AMS 2 Pro expels moisture through external air circulation. Ensure the air intake and air vent are not blocked by other objects for the best drying performance.
• For other AMS models, see the included quick start guides for usage instructions.
