Python utilities for Duet RepRap based 3D printers, including D3+Pi

find_nozzle.py

• Uses OpenCV machine vision to find circles in a camera view.
• Assumes USB camera. Could be changed for PiCam.
• Requires: OpenCV.
• Runs on: Whatever machine owns the camera
• Must run in terminal on graphic console (or VNC)

getCoordsDemo.py

• Returns a JSON object with coordinates of axis of a Duet printer
• Auto-senses RRF2 vs RRF3 printers.
• Runs on: Any machine that can reach the printer via the network.
• Does not support Duet passwords at this time.

installOpenCV.sh

• Installs openCV on the Pi system image provided by Duet
• Invoke via: bash installOpenCV.sh
• Runs for about an hour (depending on type of Pi and internet speed)
• You MAY need to enlarge your swap file during the install.

toolAlignImageDuet.py

• Creates G10 commands for tool-to-tool alignment on a multi-tool printer.
• Uses the human being for image alignment.
• Interfaces to printer to fetch XY (using getCoord from above)
• Requires: OpenCV.
• Runs on: Whatever machine owns the camera and can reach the printer via the network.
• Must run in terminal on graphic console (or VNC)

toolAlignImage.py

• Creates G10 commands for tool-to-tool alignment on a multi-tool printer.
• Uses the human being for image alignment.
• Uses the Human Bieng to enter XY coordinates.
• Requires: OpenCV.
• Runs on: Whatever machine owns the camera
• Should work for ANY toolchanging printer.
• Must run in terminal on graphic console (or VNC)

videoOnly.py

• Creates a video window with a green circle to assist in tool alignment
• All other actions are up to the user
• Should work for ANY toolchanging printer
