AI-driven FREE monitoring for 3D print failures, running entirely on the printer's own board. Requires Linux on ARM32, ARM64 or x86_64.

OctoPrint-PiNozCam

Introduction

PiNozCam watches your OctoPrint camera, spots print failures, and alerts you — or pauses or stops the print for you. Everything runs on your own machine; camera frames never leave your network unless you deliberately connect Telegram or Discord.

Features:

• Detection entirely on-device — no upload, no account, no subscription
• Notify, pause or stop when a failure is confirmed
• Telegram and Discord alerts, with buttons to check, mute, pause, resume or stop the print from your phone
• Mask out anything permanently in frame so bed clips and cables do not cause false alarms

⚠️ Requires Linux on ARM32, ARM64 or x86_64 — a Raspberry Pi, similar SBC, or Intel/AMD Linux host (Apple Silicon Macs are also supported). The detector ships as a prebuilt native binary; there is no Windows or FreeBSD build, and on those platforms the plugin reports the backend as unavailable rather than detect anything.

📱 Your printer, in your pocket

Connect Telegram or Discord: AI failure alerts land on your phone, and you can see the camera, pause, or stop the print right from the chat. Don’t wait for an alert — press Check whenever you’re curious.

Telegram	Discord

• 🔍 Check — current camera view + printer status
• 🔇 Mute / Unmute — quiet alerts for this print
• ⏸️ Pause / Resume — step in from anywhere
• ⏹️ Stop — cancel with a confirmation tap
• 🚨 Failure alert — the analysed image, boxes included
• 🖨️ Multiple printers — one chat, all your printers

⚡ How fast is it?

These are full camera-to-result checks, the rate you actually get, except †: the Jetson figure is the detection step alone. Even a few checks a minute is plenty to catch a failing print — throughput is rarely the constraint.

Light on memory too: OctoPrint + PiNozCam together stay under 512 MB — even a 512 MB Pi Zero 2 W / Pi CM0 works. A 1 GB Raspberry Pi 5 (~US$45) runs it comfortably.

🚀 First run — three decisions

1. Camera — PiNozCam checks the webcam OctoPrint already uses.
2. Sensitivity — pick a preset; you can refine it later.
3. Action on Failure — start with Alert only.

Stay on Alert only, start sensitive, and step down until false alerts stop bothering you.

🖥️ OctoPrint interface

PiNozCam adds its own OctoPrint status tab and keeps all detector controls together under Settings → PiNozCam.

🔒 Private by default

Frames, results, and settings stay on your OctoPrint machine. Nothing leaves your network unless you connect Telegram or Discord — and then only the analysed image and print status go out. Keep bot tokens secret like passwords.
