This blogpost mostly functions as a reminder to myself on how to configure Mainsail to use Zerotier. If you’re unfamiliar with any of the two, the first one is a operating system made for running a 3D printer and the second one allows for a network layer for personal computing, connecting devices over SD-WAN & VPN.
I was running Octoprint for a while, but after a tip by David from Dato I went on to explore Mainsail. Mainsail is a better way to run your printer, and it’s way faster then Octoprint. So far I’ve been running it for a week and I’m pretty happy about it! The only thing that was missing was the remote connection I had with Octoprint, made possible by Zerotier.
I couldn’t find any details on how to setup Zerotier with Mainsail, but it’s really easy:
- Flash Mainsail with the Raspberry Pi Imager (be sure to configure a 2.4Ghz network, as my Pi 3B+, doesn’t support the 5Ghz yet..).
- Follow the setup guide of Mainsail to configure your printer.
- Login with SSH to the Mainsail after it’s finished installing on the printer
- Install Zerotier on the Pi through the Linux install of Zerotier
- Configure Zerotier to use your network by using:
sudo zerotier-cli join <network_id_here>
- In my case I use Cloudflare to route a subdomain to my personal Zerotier network if you also add the IP to Cloudflare you’ll need to configure
moonraker.confwith a cors entry, allowing you to use a (sub)domain. You can do this my
vim ~/klipper_config/moonraker.confon the SSH connection of Mainsail and adding a CORS entry to
Restart the klipper/Mainsail instance and you should be good to go! (it might take a while for the DNS to resolve though!). That’s it you can now use your printer everywhere as long as it’s on!
