hi, so i bought a raspberry pi zero w, but i dont know how to install it. i have tried different headless guide on the internett, but i doesn't seem to work.
Check out http://octoprint.org/download/
If you JUST want to use it as Octoprint the easiest way is to install the OctoPi image.
Just remember that the RPi Zero W uses the same CPU like the RPi just bit faster. check https://en.wikipedia.org/wiki/Raspberry_Pi
If you plan to use a webcam in Octoprint think about another RPi or single-board-computer.
Check: https://shop.prusa3d.com/forum/software ... tml#p22791
If you power the RPi via the connector and print via Octoprint and then have a power loss the POWER PANIC
will not work!!! The RPi will crash and restart.
Question is if the Power Panic
is still working (saving position and raise the nozzle min 2mm) with a connected RPi.
We will see how the Power Panic is implemented, as long you print from the SD that should not be a problem. Let's hope for a Octoprint plugin getting the same while printing via Octoprint, as the power loss pin is available on that header.
I like the C.H.I.P. with Octoprint for that bit more, because it has a build in LiPo charger/backup, and will stay powered up during power failure.
The ESP8266/ESP32 ESP3D project https://github.com/luc-github/ESP3D
is also looking promising.
So i never worked on either octoprint or a raspberry before, how difficult is it to install and set up octoprint and do i need some connector pins for the MK3? is there a wiring diagram on what pins i need, and how many?
Check this for wiring:
The GPIO3 on the Raspberry Pi Zero W is used to reset the printer.
The GPIO8 on the Raspberry Pi Zero W will inform the RPi of power loss.
Hope that helps.
