The aim of this project is to visually and remotely monitor the printing progression, prevent failed prints, and, if necessary, launch a cancel command to stop any potential damage.

I remotely control my MK4 Prusa via the PrusaLink Integration and Home Assistant : https://www.home-assistant.io/integrations/prusalink

In order to have a better static view of what is going on, I pause the job for a while, and the extruder moves to the opposite corner, allowing me to see a perfect landscape. After that, I resume the job.

You can draw inspiration from this very nice project to integrate an ESP32-CAM with Home Assistant and ESPHome : https://haade.fr/en/blog/esp32cam-ai-thinker-homeassistant-esphome-full-configuration

I only adjusted the configuration to enable the modification of the flashlight's dimmer.

Materials :

  • ESP32-Cam
  • USB-C power supply (USB to TTL module 5V/3.3V)
  • 2 Dupont wire
  • Printed with PETG Jet Black Prusament
