Ancilla

An application to be able to manage all your 3D printers, cameras and files from one place.
Each printer and camera are launched in a separate process.
Communication between processes is done using ZeroMQ

Installation

Using Prebuilt Raspberry PI Image

1. Download Image

2. Mount SD card on your computer and flash the Image to it (using something like etcher) A. If you want to connect to you wifi network immediately and not have to join the access point to put in your credentials, go to Connect Wifi Network Manually

3. Then plug the SD card into your raspberry pi and start it up. It will take a few minutes.

4. If you didnt manually add the wifi credentials then you'll need to connect to the Raspberry Pi access point.

On first boot it will expand your partition to take up all available space on your SD card. This can be prevented by opening up the file cmdline.txt and removing the text quiet init=/usr/lib/raspi-config/init_resize.sh

Connect To Your Wifi Network

Access Point:

1. Look for a wifi network called ancilla-setup-{....} and Join the network with password ancilla1134
2. In your browser you should be able to go to http://ancilla.local If for some reason that doesn't work you can go to the IP address http://192.168.27.1
3. Bottom left of the webpage you should see a gear. Click that and modal will appear where you can add your wifi credentials. ** There is an issue where as soon as it connects it changes networks so the call to connect never returns. If it fails try refreshing the page and if you can't access ancilla.local then try going to the IP address.
4. Once connected you can switch back to your network.

Manually

Before First Boot Mount SD Card on your computer and add a file named wpa_supplicant.conf in the root directory with the following content. Be sure to replace the network ssid and psk with your wifi network.

country=us
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
  scan_ssid=1
  ssid="MyNetworkSSID"
  psk="Pa55w0rd1234"
}

Development

Setup: (Mac, linux unsure)

$ git clone https://github.com/yyuu/pyenv.git ~/.pyenv
$ git clone https://github.com/yyuu/pyenv-virtualenv.git ~/.pyenv/plugins/pyenv-virtualenv

Add the following to your .zshrc/.bash_profile:

## Pyenv
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$PYENV_ROOT/bin:$PATH"

if command -v pyenv 1>/dev/null 2>&1; then

  eval "$(pyenv init -)"
  eval "$(pyenv virtualenv-init -)"
fi

Then:

$ env PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.7.4

After install, cd in to directory and do the following:

$ virtualenv .venv --no-site-packages
$ source .venv/bin/activate
$ pip install -r requirements.txt

For the UI setup:

You can work on the UI separately by cloning the UI repo: git clone git@github.com:frenzylabs/ancilla-ui.git

Or you can pull the submodule down by running: make update-ui

Then run it with:

$ cd ancilla/ui
$ yarn install --check-files
$ yarn start

Running Dev

$ make run

Packaging

Updates the UI module, cleans it and packages it

$ make build-ui
