2GB Pi’s are scarce at the moment, so adding some 4GB versions for a bit.

Alien3D OctoPi Wifi Hotspot (See setup instructions below)

This is a ready to go OctoPi, not a kit. Just plug it in and you can be printing in minutes. Each Pi is pre-installed with OctoPrint and individually set up to keep security features per requirements by Gina at OctoPrint. Instead of providing Alien3D with your network ID and password, this device is setup to serve as a WiFi hotspot similar to Mosaic’s Canvas Hub, which you can connect to via Wifi – (see instructions below). If no networks are available, then it defaults back in to serving as a hotspot. A portion of each sale is donated to OctoPrint.

Device comes pre-built with the following:

  • Raspberry Pi 4B – 2GB RAM or 4GB RAM
  • 4 Aluminum Heatsinks
  • 32GB SanDisk MicroSD – Pre-Installed with OctoPrint as described above.
  • RGB Fan (I couldn’t just go with a PLAIN fan lol) configured in silent mode (can be setup to run full blast by changing a single pin)
  • USB-C Power Supply, 5.1v 3A, Black, UL Listed
  • Case printed in Alien Ooze (designed by INUX3D) – Check out their site for more PI case options!

Description

IP Address for accessing the Pi when connected as an Access Point (If you use an ISP that uses the 10.0.0.1 IP system, disconnect temporarily to setup the Pi connection)
Prior to 2/1/2021: WiFi Setup Page – http://10.0.0.1 • OctoPrint – Inaccessible, see changing port number below. OctoPrint is still accessible as normal once connected to your network.
After 2/1 but prior to 4/14: WiFi Setup Page – http://10.0.0.1:8080 • OctoPrint – http://10.0.0.1
After 4/14: WiFi Setup Page – http://10.0.0.1:8081 • OctoPrint – http://10.0.0.1

  1. Plug in the PI
  2. Open up your WiFi networks on your phone/tablet/PC/Mac and connect to AlienScout Setup
  3. Open a browser and go to the correct IP address listed above.
  4. Select your local WiFi network and enter the password, then save
  5. The PI will restart automatically and connect to your local WiFi. If it cannot connect it will default back to an Access Point after 180 seconds.
  6. You’ll have to find the IP address for the PI on your network, usually you can connect to your local router via 192.168.0.1 or 192.168.1.1. Once you’re logged in to your router, you can view the connected devices and the name of the device should show up as OCTOPI. Once you have the IP address to the OctoPi, you can go to that IP address in your browser to access OctoPrint. If your router supports it, you can make it assign the same IP address to that device so that it isn’t assigned a different IP address in the future.

Troubleshooting Tips

Based on some emails from those who’ve had some issues, here’s some tips to try! Most of these issues have been resolved, but just in case…

I have a PiCam installed using the slotted cam port and neither the WiFi Setup is accessible AND the cam isn’t working in OctoPrint

This is due to a port conflict, apparently that cam slot also uses port 8080, so if you want to use a PiCam, follow these steps to change the port number of the WiFi setup

  • Connect to the Pi either via monitor/keyboard or via WiFi using the Access Point connection
  • Monitors should see a command prompt…
  • WiFi connection you need to SSH into the Pi via either Putty or windows command prompt: ssh pi@10.0.0.1
  • login to the Pi using password: raspberry
  • cd /etc/raspiwifi
  • sudo nano raspiwifi.conf
  • change the port number to 7070 (don’t use 80 or it’ll conflict with OctoPrint)
  • Ctrl+X to exit, Y to save, Enter to override with the same file name
  • sudo reboot

At this point you “should” be able to access the WiFi setup page at http://10.0.0.1:7070 after connecting again to the AlienScout Access Point and your cam should be working within OctoPrint whether in access point mode or when on your local network.

When connected to the AlienScout in Setup mode, can access OctoPrint but not the WiFi Setup

There have been 3 things that have been found to cause this. (First one is outlined in the previous PiCam port issue)

  • Browser is trying to force https
    • Check your browser settings and make sure https isn’t being forced as https isn’t supported to access the WiFi setup or OctoPrint
  • For some reason port 8080 is blocked.
    • See if you can allow port 8080 on your PC’s firewall
    • Change the port number:
      • Either
        • Connect to the Pi via WiFi
          • Open up an SSH client such as Putty or if you have a command line interface installed to do it through windows command window
        • Connect a monitor and keyboard to the Pi
      •  via command line – ssh pi@10.0.0.1
      • Password is raspberry
      • Browse to folder.. /etc/raspiwifi and edit raspiwifi.conf by entering: sudo nano raspiwifi.conf
      • Double check the port number, it should be set to 8080. Change it to 7070, don’t use 80 otherwise it’ll conflict with Octoprint when serving as an access point
      • Ctrl+X to exit, Y to save, Enter to override with the same file name
      • sudo reboot
