Octoprint

An application to control (usb) 3d-printers over the network.

  • send .stl over the network (no sd cards needed)
  • setup and control the print
  • monitor the progress of ongoing prints (optionally, webcams can be added to see the visual state)

Multi 3D printer support

  • Octoprint only supports one printer per instance
  • in order to support multiple printers, we can deploy multiple docker containers
  • the different printers can then be assigned to their respective instance
  • this example sets up 2 instances for 2 priners, modify it to your needs

Requirements

Hardware

  • Debian/Ubuntu based host (RPi, Laptop, ...)
  • one USB port per 3d printer
  • Recommended: network connectivity to host (if not, only control over localhost is possible)
  • Optionally: one webcam per 3d-printer (needs additional USB ports)

Software

Deploy Octoprint with 2 printers

General

  • modify the docker-compose.yml according to your printer and webcam devices (e.g. /dev/ttyACM0 /dev/video0)
  • make sure each instance uses it's own port (default port 81 and 82)

Manual deployment with Portainer

Plain Docker Compose without Portainer

  • copy the compose file to /srv/docker/octoprint/docker-compose.yml on the host
  • cd /srv/docker/octoprint
  • start the containers with sudo docker compose up -d
  • check if containers are running sudo docker ps
  • check for any errors with sudo docker compose logs -f
  • access and configure at http://<HOST_IP>:81/ http://<HOST_IP>:82
