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

This box is designed to include :

• 1X Raspberry Pi 2 or 3 // https://www.amazon.fr/gp/product/B07BDR5PDW/ref=as_li_tl?ie=UTF8&camp=1642&creative=6746&creativeASIN=B07BDR5PDW&linkCode=as2&tag=jakinoh-21&linkId=5e622d2ffcf9847beb7cf4fa8cda2ab5 //
