Prusa Connect Uploader

Summary

Camera still uploader for Prusa Connect. Loosely based on the prusa-connect-camera-script.

Installation

Firstly, the script expects a single camera attached to the RPi via the ribbon cable (/dev/video0) If you need to support multiple cameras, use the prusa-connect-camera-script or submit a pull request.

On your RPi, do the following:

sudo groupadd --system pi
sudo useradd --system --create-home --gid pi --groups audio,video,spi,i2c,gpio pi # Only video is strictly necessary

Then sudo su pi to become the pi user and cd /home/pi, then edit /home/pi/.prusa-env to contain:

PRUSA_CONNECT_CAMERA_TOKEN=<your-token-here>
PRUSA_CONNECT_CAMERA_FINGERPRINT=<your-camera-fingerprint-here>

Generate a unique fingerprint for each camera using uuidgen. You get the token when you add the camera in Prusa Connect.

Go back to being root then edit /etc/systemd/system/prusa-connect-uploader@.service to contain:

[Unit]
Description=Prusa Connect Camera Upload Service
After=network.target systemd-udev-trigger.service
Wants=network.target
Requires=systemd-udev-trigger.service

[Service]
User=pi
Group=pi
EnvironmentFile=/home/pi/.%i
ExecStart=/usr/local/bin/prusa-connect-uploader
Restart=always
RestartSec=15

[Install]
WantedBy=multi-user.target

Then run:

systemctl daemon-reload
systemctl enable prusa-connect-uploader@prusa-env.service
systemctl start prusa-connect-uploader@prusa-env.service
systemctl status prusa-connect-uploader@prusa-env.service

If all is well you will see the capture file, then the successful upload to Prusa Connect. Note that your printer must switched on and be sending telemetry to Prusa Connect for uploads to work.

If you are building from source, I recommend you use Cross to cross compile for --target aarch64-unknown-linux-gnu and then scp the binary to your Raspberry Pi. You can use the command just cross user@host in the project to compile and upload in one step. See Just.
