Plugins
Plugins add features to your printer: camera streaming, filament tracking, a remote screen, and more. Each one installs into its own space on the printer and works alongside the factory firmware. You can remove any of them and your printer goes back to how it was.
The store is the main view in the app. With a printer added, it shows every available plugin. You can:
- Search by name or description.
- Filter by category (Camera, Filament, Screen) or view everything grouped.
- Switch between grid and list with the layout toggle in the toolbar.
Click any plugin to open it. Its page has tabs across the top:
| Tab | What it shows |
|---|---|
| Overview | What the plugin does and what it needs. |
| Documentation | The plugin's own guide. |
| Configuration | Any settings you can fill in before installing. |
| Changelog | What changed in each version. |
With a printer set up, open a plugin and click Install. Bespok3d sends it to your printer and shows live progress. It joins your installed list right away, with no app restart. To remove it, open it and click Uninstall.
Some plugins ask for one detail before they install (for example, the Spoolman Bridge asks for your Spoolman server address). The box appears on the plugin's page when your printer is set up. You can paste a full web address or just the hostname; Bespok3d tidies it up for you.
Installing several at once is safe. If you add a set of plugins together, Bespok3d applies them and restarts the printer's services just once at the end, rather than once per plugin. This keeps the printer's screen steady during a big install.
Once a plugin that has its own web page is installed (a camera stream, for example), the printer picker in the top bar grows a small arrow. Hover it for a list of everything you can open (Fluidd, the camera streams, and any page a plugin adds), and click to open it in your browser.
These plugins are confirmed working on the Snapmaker U1.
Camera (hardware accelerated). Smooth streaming for the built-in and USB cameras, using the printer's own video hardware so it stays light even with two cameras running. You name each camera when you install it (for example, internal for the built-in one and external for a USB one).
Remote Screen. Shows the printer's touchscreen in a browser tab, with full touch control: tap, drag, and type from your phone, tablet, or computer.
Good to know: the printer's stock screen can occasionally freeze on its own (a firmware quirk that also affects other custom setups for this printer), most often when opening a very long file list. Remote Screen spots this and restarts the screen for you within a second or two, no reboot needed. You may see it blink as it recovers. If the physical screen ever stays black, a power cycle always brings it back (see Troubleshooting).
RFID Spool Reader. Reads OpenSpool RFID cards on the U1's built-in reader. Tap a tagged spool and its filament details are picked up automatically.
Spoolman Bridge. Connects your printer to a Spoolman server so your spools and remaining filament stay in sync. Works together with the RFID reader so a tap updates the active spool for you.
You do not have to wait for a plugin to appear in the store. If you have a .b3 plugin file, drag it
onto the Bespok3d window or double-click it. Bespok3d checks it, adds it to your library, and offers to
install it. Your own copy is labeled local so you can tell it apart, and dropping a newer build
replaces your previous one. One bad file never blocks the others in the same drop.
Choosing a version. When a plugin is available from more than one place (your own copy, the built-in copy, an online source), its page gains a Versions tab so you can pick exactly which one to install, or switch an installed plugin to a different version.
Removing your own copy. Use the trash button on the Versions tab. If it is on a printer, Bespok3d explains your choices first: take it off both the app and the printer, or leave it on the printer.
Your plugins survive Snapmaker firmware updates. Bespok3d keeps their files safe and, after an update, offers one-click recovery to put them all back (see Printers). Some plugins also carry more than one version of an internal fix so they keep working across different firmware releases; Bespok3d picks the right one for your printer automatically.
- USB install: drop a plugin bundle on a USB stick and have the printer install it, no network needed.
- Community plugin sources you can subscribe to.
- A Create tool to build your own plugins inside the app.
