Hey everyone! I’ve been working on this open-source project called 3D-Print-Sentinel, and it’s been a game changer for my 3D printing setup. It’s basically a way to automatically monitor your prints using machine learning, and the best part? It runs entirely on a Raspberry Pi (tested on Pi 4 and 5, 4GB+ RAM)!

Here’s what it does:

• Real-time error detection using the same machine learning model from Obico (Spaghetti Detective) just on device this time!
• Automatic print pausing: If it detects something’s wrong, it sends you a notification. If you don’t respond in 2 minutes, it’ll pause the print for you!
• Integrates with OctoPrint for seamless print management.
• Home Assistant integration: You can monitor everything from a dashboard, plus get notifications on your phone with snapshots of your print.
• Secure remote access: No need to expose any ports; it uses a Cloudflared tunnel for safe remote monitoring.
• Super easy to set up with Docker Compose.

If you’re tired of babysitting your prints or wasting filament on failed jobs, this might help! It’s free, open-source, and runs locally, so no cloud nonsense. Check it out if you’re into 3D printing or have a Raspberry Pi laying around.
