3D printing: Auto Skew Calibration with a Camera and a ChArUco Board (Klipper)

In this video I introduce my open source project "Camera based skew calibration for Klipper" which automatically measures the skew on FDM 3D printers running the Klipper firmware using a low cost USB (endoscope) camera 📸 and a ChArUco board (computer vision). It automates image capture, camera intrinsics calibration, and skew solving—then outputs a ready-to-use Klipper command (SET_SKEW XY=…). 00:00 Intro 01:53 What is Skew and how we compensate it currently? 02:42 How does my project work? 03:43 Why is this cool? 04:08 What's a ChArUco board? 04:52 What do you need? 05:13 How to create the board 06:06 Camera calibration (determining camera intrinsics) Here is the Projects GitHub repository: https://github.com/undingen/SkewCamera Camera Mount: https://www.printables.com/model/1233...
