Installing plugins for OctoPrint on OctoPi 1.0.0 can sometimes throw unexpected challenges. One such issue occurs with the Bambu Printer Plugin, which may show as “Unknown” during installation and fail to appear in the Plugin Manager after rebooting. This guide walks through fixing the problem step-by-step and sneaks in a shameless plug for a handy accessory that makes filament management on the Bambu Lab X1 Carbon (X1C) even smoother.

Understanding the Issue

The problem typically unfolds like this:

  1. The Bambu Printer Plugin is installed using OctoPrint’s Plugin Manager.
  2. Instead of the usual success message, it’s logged as “Unknown”: 
    Plugin management log:
- Install Unknown: ✓
  3. After rebooting OctoPrint, the plugin isn’t visible in the interface or Plugin Manager.
  4. Checking the logs shows errors like: 
    ImportError: cannot import name 'unix_timestamp_to_m20_timestamp' from 'octoprint.util.files'

These hiccups can stem from incomplete installations, compatibility issues, or missing dependencies.

Step-by-Step Fix for the Plugin Installation

Step 1: Check System Requirements

Before diving into fixes, ensure the setup meets the minimum requirements:

  • OctoPi Version: 1.0.0 or higher
  • Python Version: 3.9 or higher

Use these commands to verify:

python3 --version
cat /etc/octopi_version

If the Python version is outdated, an update will be necessary. If OctoPi is up to date, proceed to the next step.

Step 2: Remove Partial Plugin Installations

If the plugin was partially installed, clearing out incomplete files is the first step:

  1. Connect to the Raspberry Pi via SSH.
  2. Navigate to the plugin folder: 
    cd ~/.octoprint/plugins/
  3. Delete the Bambu Printer Plugin files: 
    rm -rf octoprint_bambu_printer

Step 3: Manually Install the Plugin

  1. Download the plugin source: 
    wget https://github.com/jneilliii/OctoPrint-BambuPrinter/archive/master.zip
unzip master.zip
cd OctoPrint-BambuPrinter-master
  2. Install the plugin’s dependencies: 
    ~/oprint/bin/pip install -r requirements.txt
  3. Install the plugin manually: 
    ~/oprint/bin/python3 setup.py install
  4. Confirm the plugin installation: 
    ~/oprint/bin/pip list | grep bambu

Step 4: Restart OctoPrint

Restarting OctoPrint will finalize the installation:

sudo service octoprint restart

After the reboot, the Plugin Manager should display the Bambu Printer Plugin.

Step 5: Verify the Plugin

With the plugin visible in the interface, its functionality can be tested by:

  • Checking for a Bambu Printer tab or settings.
  • Testing connection to the printer.
  • Reviewing the logs for errors: 
    tail -f ~/.octoprint/logs/octoprint.log

A Shameless Plug: The Universal Filament Roller

While on the topic of improving workflows with the Bambu Lab X1 Carbon, here’s a small but mighty accessory that can make life easier: the Universal Filament Roller.

This roller is perfect for those running a single roll of filament without using the Bambu spool holder. It keeps filament feeding smoothly, eliminates jams, and works with various spool sizes. For businesses or hobbyists looking to save time and space, it’s a no-brainer.

Check out the Universal Filament Roller for a simple yet effective upgrade. (Yes, it’s a shameless plug, but it really is handy!)

Troubleshooting Common Issues

Plugin Still Missing After Reboot

If the plugin doesn’t appear, verify the files are in the correct directory:

ls ~/.octoprint/plugins/

If the files are missing, repeat the installation steps.

Missing Dependencies

Dependency-related errors can be resolved by installing the required modules manually:

~/oprint/bin/pip install <module_name>

Compatibility Challenges

For updates or specific compatibility notes, consult the plugin’s GitHub repository.

Wrapping Up

Manually installing the Bambu Printer Plugin and addressing dependency issues ensures a smoother OctoPrint setup for the Bambu Lab X1 Carbon. With a bit of troubleshooting, the plugin will work seamlessly on OctoPi 1.0.0.

And don’t forget about small workflow enhancements like the Universal Filament Roller. Sometimes, the simplest tools make the biggest difference. For more tips, tools, and resources, explore the PluggedIn3D website.
