Octoprint WIFI Hotspot

Having extensively used both Astroprint and Octoprint, I’ve been using Octoprint for the last few months for the extra features it has. Like telling you how much space is left on the SD card, being able to send directly from Slic3r to the printer and so on.

Astroprint could do the same things since it’s really nothing more than a pull of Octoprint with a beautiful GUI and limited controls. However it’s also targeted at a completely different audience so…who knows.

Until today, one of the things that annoyed me about both of them is their inability to create a WiFi hotspot should their normal WiFi network be absent.

I tend to bring my printer to demo’s and the only way to connect it is via USB. Which works, kinda, but Repetier Host and Pronterface are somewhat dodgy on the Mac so there’s starts and stops in communication. Whereas connections with both Octoprint and Astroprint never miss a beat.

As I said, today that changed…

I found this complete step by step description of how to do it:

Painless Wi-Fi for OctoPrint

In short, you create a list of ALL the known WiFi spots that your printer might encounter in a special file. When Octoprint starts up it tries all of those links and if none of them are found, it then creates it’s own WiFi hotspot.

You do need to download a more recent stable image of Octoprint that is configured to use the special list of Wifi hotspots, but that’s not hard to do.

You connect to the printers hotspot, and talk to the printer with an IP address of 10.0.0.5 in your browser. It works perfect. The best thing is that it’s a password protected WiFi hotspot so just anyone can’t connect to your printer during demo’s and create havoc with it.

Kenneth gave credit to the original creator of method here. This information was available last May, but in all my Google searches I never found it.

I’ve since downloaded both pages and saved them as PDF’s.

Just a little nugget of info…certainly the individuals have my sincerest thanks!
