Working Octoprint on Raspberry Pi Zero 2 W

From my benchmark and the official Octoprint account, we all know that the lately launched Raspberry Pi Zero 2 W is quick sufficient to run an Octoprint server to your 3D printer. It’s all nice, however with restricted I/O (learn as a single USB port) I've extra questions: Can I share the USB port with a webcam, 3D printer and a USB Ethernet adapter. Is WiFi quick sufficient to help a 1080p stream… is 512 RAM sufficient for all plugins I take advantage of… and so forth.

(Benchy)marking Octorprint on Raspberry Pi Zero 2 W

Raspberry Pi Zero 2 W

Raspberry Pi Zero 2 W is an superior and cheap improve to any Raspberry Pi Zero undertaking. It’s fast sufficient for Octoprint and plenty of different duties, it has sufficient RAM (512MB) to help the processor, however with a single USB port choices for utilizing it as an Octoprint server are restricted.

By default, you can be pressured to make use of a Raspberry Pi Digital camera, that connects to the digicam header on the board, as the one micro USB port shall be used for connecting to a 3D printer. With Raspberry Pi Camera priced £25 and HQ version over £70 (with a lens), this might be a way more costly possibility than choosing up a Raspberry Pi 4 and utilizing a spare webcam laying round. So I assumed it could be a good suggestion to see how Octoprint on Raspberry Pi Zero 2 W festivals in numerous configurations and the way careworn you have to be about your prints.

Greatest configuration

All viable Octoprint configurations

For every state of affairs, I'll run my Ender 3 printer, check the efficiency of the board by wanting up stats within the useful resource supervisor, and run a timelapse. This could decide the perfect/most dependable configuration for operating Octoprint on Raspberry Pi Zero 2 W.

I will even experiment with USB hubs and connecting Raspberry Pi Zero 2 W to the web by way of USB-Ethernet adapter, as my benchmarks verified this to be the quickest technique to entry the server. I'll monitor CPU efficiency and temperatures within the useful resource monitor and spotlight an important metrics.

Lastly, because the default, Octoprint stream settings are set to 480p, I'll crank these up and see how issues carry out. Masking these eventualities ought to put your fear to relaxation.

Eventualities

  1. Octoprint on Raspberry Pi Zero 2 W (efficiency benchmark)
  2. Octoprint on Raspberry Pi Zero 2 W with Raspberry Pi Cameras (480p/1080p)
  3. Octoprint on Raspberry Pi Zero 2 W with USB hub an USB camera (480p/1080p)
  4. Octoprint on Raspberry Pi Zero 2 W with USB Ethernet and different cameras
  5. Octoprint on Raspberry Pi Zero 2 W – all in, printing, timelapsing

As I don’t want one other 10 benchies on my shelf, I'll run my check dry (with out filament), determine essentially the most taxing state of affairs and full the print to show that operating Octoprint on Raspberry Pi Zero 2 W was a good suggestion certainly.

My Octoprint occasion is the most recent model (1.7.2) with the next plugin put in:

  • Mattress Visualizer
  • MQTT
  • Octolapse
  • Useful resource Monitor
  • Spool Manger

It’s a mixture of most likely the commonest plugins and it'll add a little bit of pressure to the system’s efficiency. It would signify a typical Octoprint set up with some modifications.

1. Octoprint on Raspberry Pi Zero 2 W

Because the Raspberry Pi Zero 2 W is formally accepted for the Octoprint, I do know I shouldn’t have any issues operating it straight. Since I left the webcam (and Pi Cameras) out of the equation, the Octoprint is crusing easily.
