docker-klipper-simulavr

Simple Docker image running Klipper with Simulavr, Moonraker, and mjpg-streamer.

This repo will run a GitHub action every hour to check for new code on the default branches of the Klipper and Moonraker repositories, and creates a new Docker image if there are any modifications.

Usage

Create and run the new container as you would normally do:

docker run -d \
  --name klipper-simulavr \
  --net=host \
  ei99070/docker-klipper-simulavr

This will start Klipper with a simulated Atmel ATmega micro-controller, Moonraker on port 7125, and mjpg-streamer on port 8080.

If you need to remap the default ports, run the container under the bridge network instead:

docker run -d \
  --name klipper-simulavr \
  -p 7125:7125 \
  -p 8080:8080 \
  ei99070/docker-klipper-simulavr

The default configuration files used can be found on the klipper_config folder.

This is the runtime folder structure:

/printer
  /klipper
  /klippy-env
  /mjpg-streamer
  /moonraker
  /moonraker-env
  /printer_data
    /config
      /moonraker.conf
      /printer.cfg
    /database
    /gcodes
    /logs
      /klippy.log
      /moonraker.log
      /supervisord.log
    /moonraker.asvc
  /pysimulavr

Any of these files can be overrided by mapping the folder or the specific file.

For example, here is how to override the default printer.cfg:

docker run -d \
  --name klipper-simulavr \
  --net=host \
  -v my-printer.cfg:/printer/printer_data/config/printer.cfg \
  ei99070/docker-klipper-simulavr

Klippy Extras

Some Klipper extra modules are included as part of this image, specifically:

• virtual_pins - https://github.com/pedrolamas/klipper-virtual-pins
• gcode_shell_command - https://github.com/th33xitus/kiauh

Convenience scripts

The image includes the following convenience scripts:

• enable-timelapse - installs the Moonraker Timelapse dependencies, updates the configuration files, and restart Klipper and Moonraker
• restore-klipper-repo - restores the Klipper git repository to the same point where the docker image was created
• restore-moonraker-repo - restores the Moonraker git repository to the same point where the docker image was created

Once the Docker container has started, these can be easily run:

docker exec -it klipper-simulavr enable-timelapse

Available tags

• latest: points to Klipper and Moonraker default branches
• klipper-sha-<hash>: points to the Klipper GitHub commit hash
• moonraker-sha-<hash>: points to the Moonraker GitHub commit hash

FAQ

I keep getting "MCU 'mcu' shutdown: Timer too close"

Start the container with SIMULAVR_PACING_RATE environment variable set to something like 0.2, like this:

docker run -d \
  --name klipper-simulavr \
  --net=host \
  -e SIMULAVR_PACING_RATE=0.2
  ei99070/docker-klipper-simulavr
