I should point out that NMTUI may do everything you want/need. So you may need to only run that.

** wifi setup network={ ssid="The_ESSID_from_earlier" psk="Your_wifi_password" } ** run this NMTUI

I'm having difficulty getting Octoprint to start. I've set it up in init.d and defaults. When I execute it directly I get an error about running as root. It's like it's ignoring the octoprint_user. /etc/default/octoprint: # Configuration for /etc/init.d/octoprint # The init.d script will only run if this variable non-empty. OCTOPRINT_USER=octoprint # base directory to use #BASEDIR=/home/octoprint/OctoPrint # configuration file to use #CONFIGFILE=/home/pi/.octoprint/config.yaml # On what port to run daemon, default is 5000 PORT=5000 # Path to the OctoPrint executable, you need to set this to match your installation!

This wound up being a memory issue. Python is apparently sloppy about memory management. I fixed it by creating a larger swap file and enabling it.

It still won't run.... going to clear out venv and try again.

I fixed this.... apt-get python2.7-dev install Need the python development headers installed.

I was able to get it working by following the Raspbian instructions. It works just fine for me.

I am noticing that it will periodically drop, but not what you are seeing. It stays connected for hours. I'm running Aerohive Access Points, which are enterprise grade. I find that the OPI0 wifi driver is picking AP's that are not nearby which kills performance. It does eventually find the closer AP and roam to it. Performance is a bit pokey, 26mb/s... but that could be my cheap SD card in it.

I'm getting an error and I'd like some feedback if it is a missing package (apt-get) or a bug in OctoPrint or something wrong in Python. It looks like something is blowing up with Python trying to install a package called scandir 1.3, but I'm not getting anything when I google it with the error. Thoughts? The documentation on Git was up to date... the documentation on Octoprint.org is wrong for building it from source.

The MAC address of your wifi port on your Orange Pi Zero probably starts with C8:27:A7:F9:xx:xx I obsfucated the last 4 digits of mine. The Ethernet Port MAC starts with : de:ae:b8:d7:xx:xx I needed this when I was trying to find the device on my network to SSH in. root/1234 It showed up on my network as a reasonably "fast" device with 0ms lag. I'm running a Cat 6 network with a gigabit switch. A nice pinout that Linux34 from Orange Pi posted.
