Update 2023
This have been running reliable for some years, but on a new network setup I wanted to install tailscale. After a few attempts to update the underlying debian dist for certification reasons to be able to install tailscale I think I kinda broke the Linux install.
So I felt I'd redo this. Burnt a shiny new octopi with Raspberry Imager.
A few notes:
- The script for setting pins seem are now:
/home/pi/.octoprint/config.yaml:
system:
actions:
- action: printer on
#command: gpio -g write 18 1
command: raspi-gpio set 18 op dh
name: Turn on the printer
- action: printer off
#command: gpio -g write 18 0
command: raspi-gpio set 18 op dl
confirm: You are about to turn off the printer.
name: Turn off the printer
- The camera stopped working.
- octopi reporting undervoltage:
