Version 0.3

---

Octoprint is important to control your 3D printer. I designed a box to add new features to my ender 3 like:

• Have remote control of the printer from your smartphone ( Printoid)
• Turn your printer on or off
• Turn the light on or off (useful when a camera is installed)
  see link below to understand and add this feature to OctoPrint
  https://github.com/foosel/OctoPrint/wiki/Controlling-a-relay-board-from-your-RPi
• the progress of the program to control the internal fans. It is possible for the moment to switch it on via WiringPi ( Gpio write 4 1 or 4 0). The idea is to be able to adjust the fan speed according to the internal temperature of the box

To be coming soon:

• Control the ventilation of the enclosure via the Gcode controls and according to DHT22 sensor
