Elegoo Centauri Carbon 2 Setup Guide

Before you begin

• Check that the model and version on your printer match this guide. Packaging and accessories may vary by batch.
• Prepare a stable table and leave room for movement and tubing. Open your printer manual and watch the video to locate the shipping restraints. The heated bed is the part that moves or heats up; the build plate sits on top of it and supports the print.
• Use the tools and screws specified for each step. Keep the printer disconnected from power while assembling parts and connecting cables.
• Keep the box, protective packaging and shipping screws, and store the shipping screws separately from the assembly screws.

Unboxing and assembly steps

Follow the steps in order and check the images below each step. Click an image to view it or open its reference. Compare screw positions and connections with the images in the printer manual as you assemble the printer.

1. Check that your model is Centauri Carbon 2 or Carbon 2 Combo. Do not use the original Centauri Carbon manual, because the parts and connections differ.

   

2. Open the carton and remove the screen, tool kit and foam from the printer. Open the glass door and take out the top cover, packaging and accessories inside.

   

   

3. Place the printer on a stable table. Use a 2.5 mm hex key to remove the three heatbed shipping screws marked in blue on the manual's unboxing page. Connect the screen ribbon cable with its gold contacts facing upward, then slide the screen into its slots and press down until it locks.

   

4. Fit the nozzle wiper to the rear panel using two FM3×12 screws at the top and two PM3×4 screws at the bottom. For Combo, remove the silicone plugs from the mounting holes and secure the CANVAS bracket with two PM3×50 screws. Attach the unit with three PM3×8 screws. Fit the filament hub above the toolhead with two PM3×6 screws.

   

   

   

   

5. For Combo, connect the four PTFE tubes between CANVAS and the filament hub and secure them with the clips. Fit the spool-holder bases with eight PM3×12 screws, then insert each holder in its numbered position. Connect the four-pin cable with its angled end at the rear of the printer and its straight end at CANVAS. Fit the top-cover extension as illustrated. Check that the build plate sits flat and all cables and tubes are clear of moving parts.

   

6. Check that each spool holder is secure in its correct position and the spool turns freely. If your spool size requires an adapter, fit a suitable one so the spool cannot wobble or fall.

   

7. Check the rear power inlet and the printer's rating. Connect power, turn on the printer and complete the on-screen setup, calibration and bed leveling.

   

8. Load filament and set its material type and color. If the spool supports RFID, scan its tag with the CANVAS reader and confirm the information on the screen. Otherwise, enter the material type and color manually.

   

   

9. For multicolor printing, match the model colors to the actual CANVAS slots. Check that enough filament remains and the spools are not tangled.

   

10. Open ELEGOO Slicer and select the correct printer model and nozzle size. Follow the software instructions to connect the printer to the network, and use ELEGOO Matrix if it suits your setup.

    

    

11. Start with a small PLA model and its matching material profile. Watch the first layer and check that filament feeds and extrudes consistently.

    

12. When printing finishes, wait for the heatbed and model to cool. Remove the model, clear any debris and clean the plate before the next print.

    

First startup and calibration

1. Before connecting power, remove the foam and shipping restraints, then use a 2.5 mm hex key to remove the three heatbed shipping screws marked in blue in the unboxing image above. Do not remove the CANVAS or screen assembly screws. Check the build plate, screen connection, tubes and cables before startup.
2. Choose the language and settings on the touchscreen. For remote printing, connect the printer to the network and pair it with the app.
3. Run the checks and calibrations requested by the setup screen and wait for them to finish. Keep tools and models off the build plate, and do not touch moving parts.
4. If an error appears, photograph the message and error code, then check the assembly and printer manual before running calibration again. Once setup finishes successfully, you can load filament.

Fit and load filament

1. Start with an easy material such as PLA and select its slicer profile, which contains preset settings for that material. Check that the spool and filament suit your printer and feeding system. Verify compatibility before using flexible or abrasive filament.
2. Fit the spool so it can turn freely. Hold the filament end to prevent it from springing loose and tangling, then gently feed it into the path. Do not force it if you feel resistance.
3. Select the filament-loading command on the touchscreen as described in the printer manual. Wait for the nozzle to heat automatically, check that filament comes out, then continue with the on-screen steps.
4. Set the filament type and color for each channel or toolhead, and match their order in the slicer to the printer. Similar colors do not necessarily mean the same material type.
5. Before changing a spool, choose Unload on the touchscreen to remove the filament. Do not force filament out of a cold toolhead.

Download printer software

The desktop software for this printer is ELEGOO Slicer. This is the slicer: use it to open your model, select the printer and filament settings, and prepare the file for printing.

Download ELEGOO Slicer for your computer

1. Open the link on your computer, choose the version for your operating system and install the software.
2. Open the software and select your printer model, nozzle size and build plate type.
3. Choose the filament profile, which provides preset material settings, and match the color channels to the printer for multicolor printing.
4. If your printer model is missing, update the software and printer profiles from the same official source before continuing; do not choose a similarly named model.

The GitHub download page belongs to ELEGOO. Open the latest stable release, expand Assets and select the installer for your operating system.

Your first print: start with a small model

1. Start with a test model stored on the printer if one is available. Before printing, check that the filament type required by the file matches the material you have loaded.
2. To print your own file, download ELEGOO Slicer from the software section above. Open the slicer and select your printer model, nozzle size and build plate type; do not use another printer's profile.
3. Open the model in the slicer and place it within the build plate boundaries. Select the filament profile and keep the recommended settings for your first attempt; do not start at maximum speed.
4. For multicolor printing, assign each color to the correct channel or toolhead. If the file uses a prime tower, a printed structure used to clear the nozzle between colors, check that it fits within the build plate alongside the model and supports.
5. In the slicer, click Slice to prepare the file, then open Preview. Review the first layer, supports, print time and filament use, then send the file using a method your printer supports: over the network or via storage media.
6. Watch the first layer: the lines should be joined and adhere to the plate without dragging or lifting at the edges. If adhesion fails, stop the print, clean the plate and check calibration and settings before trying again.

After printing

• Wait for the nozzle, heated bed and model to cool before touching them. If the build plate is flexible and suitable for this method, remove it and flex it gently to release the model, then refit it flat.
• Remove the starting line and filament debris. Check for small pieces under the build plate or on the heated bed before refitting the plate.
• Avoid touching the print surface with your fingers. Clean it using a method suitable for the plate type, and check compatibility before using any cleaner.
• Store filament in a dry place and secure its end when removing a spool to prevent tangles. Check the tubes, nozzle wiper and spools regularly.
• Follow the maintenance schedule in your printer manual. Do not apply grease or oil unless the manual specifically instructs you to.
