Extprint3r !!link!! May 2026
Subject: 🔥 The extprint3r is here – meet your new favorite extrusion analyzer
Body:
Hey everyone,
I’ve been putting together a tool called extprint3r – and it’s finally ready to share.
What is it?
extprint3r is a lightweight, real-time extrusion monitoring and visualization tool for 3D printers (Klipper/Marlin + OctoPrint compatible). It tracks your extruder’s behavior down to the mm/s and mm³/s, then gives you clean graphs and alerts.
Why I built it:
I kept running into under-extrusion issues mid-print without any warning. Logs were hard to read, and I wanted something that just shows me what’s happening, live.
What it does now:
- Live extrusion rate graph (speed + flow)
- Detects skipped steps / clogs in real time
- Simple web dashboard (no cloud required)
- REST API for automation / macros
- Works with USB or serial-connected printers
Quick start (Linux / Raspberry Pi):
git clone https://github.com/yourname/extprint3r
cd extprint3r
pip install -r requirements.txt
python extprint3r.py --port /dev/ttyUSB0
Then open http://localhost:5000
Roadmap:
- Pressure advance auto-tuning
- Spool weight estimation
- Filament runout prediction (not just detection)
Looking for:
- Testers with different printer boards (SKR, RAMPS, Duet)
- Feedback on the UI
- Ideas for better clog detection heuristics

ExtPrint3r is a browser-based exploit designed for that allows users to disable or "kill" managed extensions (such as those used for school or work monitoring). It is the successor to the now-outdated
tool and relies on a vulnerability where printing iframes can cause certain browser processes to hang or terminate.
Below is a general guide on how it is typically used based on documentation from the Blobby-Boi GitHub repository How to Use ExtPrint3r Launch the Exploit : Access the ExtPrint3r tool via its hosted web interface. Click the button to start the process. Locate the Extension ID Navigate to chrome://extensions
Identify the extension you want to disable and copy its unique (a long string of random letters). Find a Web-Accessible Resource In your browser, go to chrome-extension://[EXTENSION_ID]/manifest.json Look for a section titled web_accessible_resources . Copy the path of any explicit file listed (e.g., images/icon.png or a specific Confirm the Resource manifest.json in your URL with the resource path you copied. Verify the URL (e.g., chrome-extension://[ID]/images/icon.png
) loads correctly. This URL is required for the exploit to target the specific extension. Execute the Kill Subject: 🔥 The extprint3r is here – meet
Return to the ExtPrint3r interface and follow the prompts to input your target URL/ID.
The tool typically uses a "Print" loop that forces the extension to crash. Important Security Considerations Vulnerability Status
: ExtPrint3r exploits a specific permissions bypass (referenced as CVE-2025-6179 ) in managed ChromeOS devices. Advanced Use Only
: This guide is intended for advanced users and research purposes. Misuse can lead to instability in your operating system.
: Google frequently updates ChromeOS to block these exploits. If you have updated to a very recent version (v135+), the exploit may no longer be effective. GitHub - killsecurly/blobbyboi-extprint3r
2. Open, Extensible Firmware
- Deterministic motion control: Real-time stepper control with 32-bit MCU support and advanced jerk/acceleration profiles.
- Plugin API: Lua/JavaScript runtime for on-device plugins that can add custom motion primitives, custom G-code handlers, or sensor-driven behaviors.
- Over-the-air updates: Signed firmware delivery with rollback and staged rollout for fleets.
The Comedy of Error States
Modern computing has eliminated many error states: no more IRQ conflicts, no more jumpers on dip switches. But extprint3r preserves a museum of failure. Its error messages are koans: Live extrusion rate graph (speed + flow) Detects
- “PC load letter” – A phrase so nonsensical it became a meme. (What is PC? Why must I load a letter? Is the letter a projectile?)
- “Ready” (but nothing prints)
- “Processing” (for four hours)
- “Low on magenta” (when printing a black-and-white text document)
These are not bugs. They are the extprint3r’s way of reminding you that it has a will. It is the Heideggerian tool that breaks, revealing its presence only through its brokenness. When the hammer breaks, you see the hammer. When extprint3r fails, you see the absurdity of your faith in deterministic systems.
4. Advanced Slicing Integration
- Native slicing engine: Fast, parameter-rich slicer optimized for printer profiles and materials with layered preview and estimated print-time/consumption.
- Profile marketplace: Share and download validated profiles for specific printers, materials, and part goals (strength, surface finish, speed).
- Adaptive slicing: Variable layer height driven by geometry and part orientation to balance surface quality and throughput.
Competitive Advantages
- Unified multi-technology support reduces fragmentation across print labs.
- Edge AI-driven recovery reduces scrap and operator intervention.
- Modular hardware enables gradual upgrades and hybrid tooling.
- Profile marketplace accelerates onboarding and repeatable quality.
