Monoprice Maker Select Ultimate 3D Printer User Manual

Introduction

The Monoprice Maker Select Ultimate 3D Printer (Model 115710) is designed for professional-quality 3D printing. It features a fine layer resolution down to 20 microns (0.02 mm) and a rigid metal frame for stable operation, allowing print speeds up to 150 mm/s. This printer includes a heated build plate, making it compatible with various filament types such as PLA, ABS, PVA, and HIPS. Printing can be initiated from a computer via USB connection or directly from an SD card. It supports Microsoft Windows, Mac OS X, and Ubuntu Linux operating systems. With an operating noise level below 49dBA, the printer is suitable for diverse environments.

Safety Information

• Always operate the printer in a well-ventilated area.
• Do not touch the print nozzle or heated bed during operation or immediately after, as they reach high temperatures and can cause burns.
• Keep hands clear of moving parts during operation to prevent injury.
• Ensure the power cable is securely connected and routed to prevent tripping hazards.
• Do not leave the printer unattended for extended periods during operation.
• Keep children and pets away from the printer during use.

Setup

1. Unpacking and Placement

Carefully remove the printer from its packaging. Inspect for any visible damage. Place the printer on a stable, level surface with adequate space around it for ventilation and access.

2. Connecting Power and USB

Connect the power cable to the printer's power input port and then to a suitable electrical outlet (120 VAC, 50/60 Hz, 4A). If connecting to a computer, use the provided USB cable.

3. Initial Inspection and Filament Loading

Before powering on, ensure all screws are tightened and moving parts are free from obstruction. Load your chosen filament onto the spool holder and feed it into the extruder according to the printer's on-screen instructions or manual.

4. Bed Leveling

Accurate bed leveling is critical for successful prints. The printer provides an automated flow for bed leveling. Follow the on-screen prompts to adjust the print bed. For optimal results, it is recommended to verify bed level periodically and consult online resources or forums for advanced leveling techniques if needed.

Operating Instructions

1. Preparing Print Files

Prepare your 3D model (.STL or .OBJ) using slicing software (e.g., Cura, Simplify3D) to generate a G-code file. Save the G-code file to an SD card or transfer it directly to the printer via USB.

2. Starting a Print

Insert the SD card into the printer's slot. Navigate the printer's menu using the control knob to select your desired G-code file. Confirm the selection to begin the printing process. The printer will preheat the nozzle and print bed before starting.

3. Monitoring and Adjusting

Monitor the initial layers of your print to ensure proper adhesion and extrusion. Minor adjustments to bed leveling can sometimes be made during the first few layers if necessary. The open frame design allows for improved airflow, contributing to consistent print quality.

4. Compatible Filaments

The heated print bed and metal extruder allow compatibility with a wide range of filaments, including:

• PLA (Polylactic Acid)
• ABS (Acrylonitrile Butadiene Styrene)
• PVA (Polyvinyl Alcohol)
• HIPS (High Impact Polystyrene)
• Flexible TPE
• Specialty filaments like metal and wood composites

Maintenance

1. Print Bed Cleaning

Regularly clean the print bed surface with isopropyl alcohol to ensure optimal adhesion and prevent residue buildup.

2. Nozzle and Extruder Maintenance

The anti-clogging gear feeder is designed for reliable filament feeding. If extrusion issues occur, inspect the nozzle for blockages and clean as necessary. Refer to the manufacturer's guidelines for specific cleaning procedures.

3. Mechanical Inspection

Periodically check all screws and connections for tightness. Loose components can affect print quality and printer stability. Ensure linear bearings and rods are clean and adequately lubricated according to manufacturer recommendations.

4. Fan Inspection

Inspect cooling fans for dust accumulation or unusual noises. Clean fans as needed to maintain proper airflow and prevent overheating of components.

Troubleshooting

Common Issues and Solutions:

• Poor Print Adhesion: Re-level the print bed. Ensure the print bed is clean. Adjust print bed temperature. Apply an adhesive (e.g., glue stick, hairspray) if necessary.
• Filament Not Extruding: Check for a clogged nozzle. Verify filament is loaded correctly and not tangled. Ensure extruder temperature is appropriate for the filament type.
• Layer Shifting: Check for loose belts or pulleys. Ensure the printer is on a stable surface. Reduce print speed if necessary.
• Heater Error: This indicates a problem with the heating element or temperature sensor. Power off the printer immediately. Check all cable connections to the hot end and heated bed. If the issue persists, contact technical support.
• Noisy Operation: While the printer operates below 49dBA, excessive noise may indicate loose components or worn fans. Inspect and tighten screws, and check fan operation.

For more detailed troubleshooting, consult online communities, forums, or the manufacturer's support resources.
