🛠️ Geeetech M1 Klipperization & Upgrade Project

Welcome to the build guide for transforming your humble Geeetech M1 into a lean, mean, Klipper-powered printing machine. This README outlines the upgrades, installation steps, and configuration notes for the project.

💡 Help me fund a 3D scanner so I can stop squeezing magic out of Polycam and a Razor phone.

🛠️ Installation Highlights

• Mainboard & Pi Setup

  • Flash Klipper on the Pi Zero 2W using the Simple AF config
  • Connect Pi to SKR Pico via USB
  • Wire power and comms with care—use ferrules for safety and reliability

• Printhead Upgrade

  • Swap stock hotend for A1 Mini
  • Mount Creality K1 extruder and calibrate steps/mm in Klipper
  • Install Microprobe and configure mesh leveling

• Power Integration

  • Mount internal 100W PSU
  • Ensure tidy cable management and proper airflow

• Camera Streaming

  • Connect camera to Pi
  • Configure MJPG-streamer or Moonraker for live feed access
