Octopi 3D print servers on Raspberry Pi3

Engineers should make their own tools! In that tradition, I have just revamped my Octopi 3D print servers to use the new Pi3 boards. I have a Lulzbot Mini and TAZ6 (which I recommend with no affiliation to Lulzbot – it’s just genuinely a pleasure when 3D printers work…), and built two new servers to enable these machines. It’s more essential for the Mini, so it doesn’t tie up another machine, but useful for concurrent jobs etc – and I like the visual feedback from the webcam since the printers are in another room!

For this build, I am using a Raspberry Pi 3 with 2.5A PSU , and these rather nice Eleduino cases with quiet fans built in. (Note these don’t fit over installed heatsinks, but should enable cool operation – I’m not overclocking, but some of my BB-8 build prints are over 30 hours – another reason for the revamped server builds…)
Software comes from Octopi as a fully-built Pi image, and requires just a little setup to be fully functioning. Follow their instructions on security and renaming the images for multiple devices etc. I am using ethernet rather than WiFi, and used fixed IPs. Setup was painless apart from finding suitable USB webcams to use. (In previous servers, I used the Pi camera which is decent, but not very user friendly with its short ribbon cable…) I settled on generic Logitech C310s and these worked out of the box with standard webcam settings.

Once everything was working, I installed the units in their new home and can now connect with browser links from my office.
As you can see, nothing vastly complex about the build, but a great use of fairly low cost parts to add good functionality to my home ‘lab’. Hope this is useful. Now back to my BB-8 build 😉
