Important Notes

• Do not place the printer in a highly vibrating or unstable environment, as machine vibrations can affect print quality.
• Do not touch the nozzle or heated bed while the printer is in operation to avoid burns and personal injury from high temperatures.
• After printing, promptly utilize the residual heat in the nozzle to effectively clean the filament residue using a suitable tool. Avoid direct contact with the nozzle to prevent potential burns.
• We recommend using ELEGOO’s slicing software to ensure the proper functioning of the machine and achieve optimal printing results.
• Perform regular maintenance on the printer by cleaning the machine body with a dry cloth to remove dust and any sticky filament residue. Ensure the printer is powered off before cleaning.
• Regularly inspect and clean the printer’s cooling fans to prevent dust buildup, ensuring optimal performance and extended service life.
• Be cautious of the machine’s high-speed moving parts to avoid any potential pinch hazards.
• The Z-axis of the machine utilizes lead screws for its moving parts. Apply lubricating oil as needed to ensure smooth movement.
• This equipment is used by skilled person. This equipment is not suitable for use in locations where children are likely to be present.
• In case of an emergency, directly turn off the power.
• Ensure the machine is properly grounded for safe operation. Failure to properly ground or neglecting to ground the machine can increase the risk of electrical leakage.
• If the machine is not in use for an extended period, please turn off the power and unplug the power cord.
• To ensure optimal performance, each ELEGOO product undergoes rigorous printing tests before shipping. Minor test marks on the printer, small amounts of residual filament on the nozzle, or slight nozzle discoloration are normal and will not affect functionality.

Printer Component Introduction

CANVAS Component Introduction

Included Accessories

Tool Kit 

Screws for Different Accessories

Printer Installation

1. Take out the foam, touchscreen, and toolbox from the printer.
2. Use the 2.5 mm Allen key to remove the 3 screws marked in blue to unlock the heated bed.
3. Insert the Flexible Printed Circuit (FPC) into the touchscreen port by pressing the terminal as pictured. Make sure the gold contacts face upwards for correct orientation.
4. Insert the screen into the slot on the printer and press down to lock it in place.

CANVAS Installation 

1. Attach the CANVAS mounting bracket to the machine using 2 PM3x50 screws. (Remove any silicone plugs from the top mounting holes before installation.)
2. Mount the CANVAS feeding module onto the bracket using 3 PM3x8 screws.
3. Install the filament hub onto its bracket. Insert the hub’s metal tube downward into the printhead’s pneumatic fitting, then secure with 2 PM3x6screws.
4. The filament hub installation is now complete.
5. Install the spool holder mount onto the machine’s aluminum profile using 8 PM3x 12 screws. (Ensure the mount sits flush against the profile’s stepped surface for a secure fit.)
6. Push each spool holder down into the mounting bracket until it snaps into place. Repeat this for all four holders.
   Note: Make sure each holder is installed in its designated numbered position to ensure the filament recycling function works properly.
7. Insert one end of each PTFE tube into the four pneumatic fittings on the top of the CANVAS module, then insert the other end into the four pneumatic fittings on the top of the filament hub.
8. Use the clips to bundle the four tubes neatly together.
9. Connect the 4-pin cable: insert the angled connector into the CANVAS port on the back of the machine, and the straight connector into the 4-pin port on the right side of the CANVAS module.

The CANVAS installation is now complete.

Filament Loading 

1. For RFID-enabled spools, hold the tag against the recognition area on the CANVAS until you hear a confirmation beep.
2. On the touchscreen, select the corresponding number for the spool holder where the filament will be installed, then tap “Confirm” to automatically write the filament information.
3. Mount the filament spool onto its numbered holder and insert the filament into the matching inlet on the CANVAS. When the filament detection switch senses the filament, the machine will automatically feed it to the ready position.
4. Repeat the above steps for all filaments to be loaded.
   Note:
   Push the spool fully into place and seat it against the stop on the holder to prevent it from falling off or becoming tangled.

1. For spools without RFID tags, manually enter the filament information.
2. Enter the material details (brand, type, color) for each spool on the screen.
3. Complete the loading for all non-RFID spools.

Note:
Filament with RFID tags can also be registered manually if preferred.
