Creality 3DPrintMill User Manual

Introduction

This manual provides comprehensive instructions for the Creality 3DPrintMill 3D printer. It covers setup, operation, safety, and troubleshooting to ensure optimal user experience. The 3DPrintMill is a gantry-style 3D printer designed for continuous printing with an infinite Z-axis capability, featuring an A-frame structure for stability.

The printer's main components include:

• X-axis Gantry: Houses the print head and moves horizontally.
• Y-axis Bed: The print surface that moves along the Y-axis.
• Z-axis: Provides vertical movement for the gantry.
• Extruder: Melts and deposits filament.
• Hotbed: Heated print surface for better adhesion.
• Control Screen: For user interface and operation.
• Filament Holder: Supports the spool of filament.

Safety Notes

Please adhere to the following safety guidelines to prevent personal injury or property damage:

• Use the printer only as described in this manual.
• Do not place the printer near heat sources, flammable, or explosive materials. Ensure a well-ventilated, low-dust environment.
• Avoid exposing the printer to strong vibrations or unstable environments, as this can affect print quality.
• Use recommended filaments (e.g., ABS, PLA) for calibration and testing.
• Use only the provided power cable and ensure it is connected to a grounded three-prong outlet.
• Do not touch the nozzle or print surface while the printer is operating, as they can be very hot. Keep hands away from moving parts.
• Do not wear loose clothing or gloves that could get caught in moving parts.
• Use provided tools for cleaning and maintenance. Never touch a hot nozzle directly.
• Clean the printer regularly. Always turn off the power before cleaning. Use a dry cloth for general cleaning and glass cleaner or isopropyl alcohol for the print surface.
• Children under 10 years should only use the printer under adult supervision.
• The machine has a safety protection mechanism. Do not manually move the nozzle or print platform during startup, as this will cause the device to power off.
• Users must comply with local laws and regulations and use the product responsibly and legally.

Assembly Instructions

Follow these steps for assembling the 3DPrintMill:

1. Install the Profile Support Frame: Attach profile supports 1 and 2 to the bottom of the machine using four M5x12 hexagon flat head screws.
2. Install X/Y Axis Belt Assembly: Mount the X/Y axis belt assembly. Ensure proper alignment and tighten screws. If interference occurs between profile bracket 2 and the assembly, loosen and retighten extrusion motor screws as shown in Fig.1.
3. Install the Spool Holder: Attach the spool holder using M5T nuts and M5x8 hexagon socket flat head screws.
4. Install the Display: Secure the display assembly using M5x8 flat head screws and M5 T-nuts.
5. Cable Connection: Connect the display cable, Y-axis limit line, and broken detection line. Insert the Teflon tube into the pneumatic connector. Ensure the correct input voltage is selected (115V/230V) before connecting the power cord. Do not connect or disconnect cables while the machine is powered on.

Operation Guide

Leveling:

1. Move the X-axis to the nozzle-belt contact point, slightly pressing the nozzle onto the belt.
2. Push the two limit switches against the X sliding block to lock the limit.
3. Return the printer to the origin via the screen. Adjust the Y-axis end-stop adjusting screw to align the nozzle with the belt. Tighten the Y-axis end-stop screw.
4. If there is a gap or excessive contact between the nozzle and belt, slightly adjust the leveling nut.

Preheating:

Access the 'Temperature' menu on the control screen. Set the desired nozzle and bed temperatures (e.g., 200°C for the nozzle) and select 'Preheat PLA' or manually adjust settings.

Load Filament:

Once the target temperature is reached, press and hold the extruder spring. Insert the filament into the charging detection hole and then into the small hole of the extruder until it reaches the nozzle.

Start Printing:

1. Install the slicing software (e.g., CrealityBelt) by double-clicking the installer.
2. Open the software.
3. Select the language, then navigate to settings to add the corresponding printer model. Customize print settings as needed.
4. Open the file you wish to print. Ensure file names use Latin letters or numbers.
5. Generate G-code and save it to the storage card.
6. Insert the storage card into the printer and select 'Print from Card' to start printing.
