Nova Fleet is a local-first printer fleet manager for Nova3D resin printers and SDCP 3.0 compatible resin printers. It provides a polished Windows desktop app and an Android companion app for monitoring printers, browsing printer storage, and managing local print jobs on the same LAN.
Nova Fleet is designed for small resin-printing workspaces that run more than one printer and need a practical local dashboard instead of checking every printer manually.
It can:
- show all configured printers in one fleet overview;
- track online, printing, paused, error, and offline states;
- show active print progress, current layer, total layers, elapsed time, and estimated remaining time when the printer exposes that data;
- list files stored on supported printers;
- upload, delete, and start
.cwsfiles on supported Nova3D HTTP printers; - list
.ctbfiles on SDCP 3.0 compatible printers; - store printer profiles locally on the device;
- work without a cloud account or remote server.
Nova Fleet currently supports two local printer protocols.
| Mode | Typical port | File type | Current support |
|---|---|---|---|
| Nova3D / Photonic3D HTTP | 8081 |
.cws |
status, files, upload, delete, print, pause/resume, stop |
| SDCP 3.0 | UDP 3000, TCP 3030 |
.ctb |
discovery, status monitoring, file listing |
SDCP upload and remote print commands are intentionally disabled for now. SDCP printer models can differ in command behavior, so Nova Fleet only enables the SDCP operations that have been implemented defensively: discovery, status, and file listing.

- Install and open Nova Fleet.
The Android device and printers must be connected to the same Wi-Fi/LAN. Some routers isolate Wi-Fi clients by default; disable client isolation if the app cannot reach printers that are visible from another device.
- Make sure the printer and the app device are on the same local network.
- Open Add printer.
- Enter a clear display name, for example
Resin Lab 01. - Enter the printer IP address.
- Select the correct protocol:
- choose Nova / Photonic3D for older Nova3D HTTP printers;
- choose SDCP 3.0 for newer printers that use SDCP.
- Confirm the port:
- Nova / Photonic3D usually uses
8081; - SDCP 3.0 usually uses TCP
3030and UDP discovery on3000.
- Nova / Photonic3D usually uses
- Keep the polling interval at
10 secondsor higher for older firmware. - Save the profile and refresh the fleet.
Demo printers are included on first launch so the interface is not empty. You can remove the demo profiles from the Printers page.
Nova Fleet talks directly to printers on the local network.
For Nova3D / Photonic3D printers:
- HTTP access to
http://PRINTER_IP:8081 - Browser check:
http://PRINTER_IP:8081/file/list
For SDCP 3.0 printers:
- UDP discovery on port
3000 - WebSocket status and file-list requests on TCP
3030 - WebSocket URL:
ws://PRINTER_IP:3030/websocket
On Windows, allow Nova Fleet through Windows Firewall for private networks. If ping or browser access works but Nova Fleet does not, firewall rules for UDP 3000 or TCP 3030 are the first thing to check for SDCP printers.
The SDCP path is not a simple HTTP status endpoint. Nova Fleet uses the SDCP flow expected by SDCP 3.0 printers:
- Send discovery packet
M99999over UDP port3000. - Read the printer response containing
MainboardIP,MainboardID, and device name. - Open
ws://PRINTER_IP:3030/websocket. - Request status with SDCP command
0. - Request storage file lists with SDCP command
258. - Normalize returned
.ctbfiles into Nova Fleet's file table.
If file listing fails, Nova Fleet keeps the printer online when status data is still available. A file-list problem should not incorrectly mark a working printer as offline.
- Confirm the IP address is correct.
- Confirm the computer/phone and printer are on the same LAN or VLAN.
- Restart the printer if its embedded service stopped responding.
- Check whether DHCP changed the printer IP.
- On Windows, allow Nova Fleet through the firewall.
- For SDCP, make sure UDP
3000and TCP3030are reachable.
- Use
.cwsfiles. - Confirm the printer has enough storage.
- Avoid sending many requests while the printer is busy.
- Very large uploads can take several minutes.
- Confirm the printer stores printable files as
.ctb. - Confirm the files are on local or USB storage exposed by SDCP.
- Refresh after the printer finishes scanning or writing storage.
- If status works but files do not, the printer may reject command
258for that storage path.
Nova Fleet stores printer profiles locally on the current device. It does not require a cloud account and does not send printer data to a hosted backend.
On Windows, printer profiles are stored in the Electron application data folder as printers.json.
