We have 7 felixprinters at our school (7 x TEC 4.1). Often we forget to cut them from the power over weekend. We wanted a solution with a better manual interface, a camera to watch the print remotely and the possibility to switch them off remotely. Fortunately there is octoprint and octopi.
We use Raspberry Pi 3B+'s with the raspi camera and the official Raspberry Pi touch display. A 5 V cooling fan 50 mmx50 mmx10 mm (e.g from MANOUII (amazon)) and a relay breakout board (e.g. relay shield from wemos.cc).
To reduce the design work I combined some designs from thingiverse.
dmesgto get device name.
bash cd Downloads sudo dd of=/dev/sdc if=2018-04-18-octopi-stretch-lite-0.15.1.img bs=1M
Please also refer to OctoPi’s README, especially the “How to use it” section.
Make sure you've installed OctoPrint and installed TouchUI from the 'Plugins Manager'.
Make sure you've your touchscreen working by installing the required drivers.
Get the TouchUI boot files + install scripts:
git clone https://github.com/BillyBlaze/OctoPrint-TouchUI-autostart.git ~/TouchUI-autostart/
Run the install helper
