4.2 Power Connection
Connect the power cable to the printer and then to a grounded electrical outlet. Power on the printer using the main power switch, typically located at the rear or side of the unit.
4.3 Extruder Installation
If the extruder is not pre-installed, carefully insert it into the designated slot on the print head assembly. Ensure it clicks securely into place. The Sketch 3D printer includes a replaceable extruder with a 0.4 mm nozzle, optimized for PLA and Tough PLA.
4.4 Filament Loading
Follow the on-screen instructions on the printer's touchscreen interface to load filament. Insert the end of the filament spool into the designated loading port until the printer detects it and begins feeding. Ensure the filament type matches your print settings.

4.5 Software Installation and Connectivity
The MakerBot Sketch Large utilizes cloud-based 3D printing software for file management. Access MakerBot Cloud via a web browser or download the MakerBot Print application for your PC or Mac. Connect your printer to your local Wi-Fi network as prompted by the printer's touchscreen or software. This enables wireless project sharing and queue management.

5. Operation
5.1 Preparing a Print File
Use the MakerBot Cloud platform or MakerBot Print software to prepare your 3D model (.STL files are commonly used and converted). Adjust print settings such as layer resolution, infill, and supports as needed. Ensure the selected filament type in the software matches the loaded material.
5.2 Starting a Print
Once your file is prepared and sliced, send it to your MakerBot Sketch Large printer via the software. Confirm the print job on the printer's touchscreen. The printer will initiate the heating process for the build plate and extruder before beginning the print.

5.3 Monitoring a Print
The MakerBot Sketch Large features a built-in camera for remote monitoring. You can observe the printing progress through the MakerBot Cloud platform or the MakerBot Print application on your device.
5.4 Removing a Print
After a print is complete and the build plate has cooled, carefully remove the flexible build plate from the printer. Gently flex the plate to detach the printed object. Use the provided spatula if necessary to assist in removal, taking care not to damage the print or the build plate surface.
6. Maintenance
6.1 Cleaning the Build Plate
Regularly clean the flexible build plate with isopropyl alcohol to ensure optimal print adhesion. Ensure the plate is cool before cleaning.
6.2 Extruder Maintenance
The extruder is designed to be replaceable. If you experience consistent printing issues related to extrusion, consult the MakerBot support resources for guidance on cleaning or replacing the extruder.
6.3 Particulate Filter
The printer includes a pre-installed particulate filter. Refer to the MakerBot official documentation for recommended inspection and replacement schedules for the filter to maintain air quality and printer performance.
7. Troubleshooting
This section addresses common issues you might encounter. For more detailed troubleshooting, refer to the MakerBot support website.
- Print Adhesion Issues: Ensure the build plate is clean and level. Adjust the initial layer settings in your slicing software.
- Failed Prints: Check filament loading, extruder condition, and print settings. Ensure the model is properly supported if necessary.
- Connectivity Problems: Verify Wi-Fi connection. Restart the printer and your computer/router. Ensure MakerBot Cloud/Print software is up to date.
- Extrusion Problems: Check for clogged nozzles or tangled filament. The extruder may need cleaning or replacement.
