its a cisco meraki mr18 access point using wpa2-psk security, password is 14 characters. i might try another wireless usb unit to see if its a hardware issue.

thanks thunder
wellā¦ the new update does fix connection for a few routersā¦
but, it seems like maybne the stock wifi dongle is crap overall.
if we can find a cheaply available, linux ready wifi adapter, maybe thats the way forward on this front.
the existing adapter works for most folks, but it seems like its ā¦ garbage overall.
wifi dongles are cheapā¦ so if we can narrow down additional support for another one, then i can add native support for it to the build.
I am sorry i cannot repro your issue on my router. i use a open WRT build router for mine, and it doesnt seem to disconnect. at least theres a lot of options for youā¦
anyone want to put forward a cheap wifi dongle we can support? or i can look into modifying the driver for the included adapter, but theres not much motivation for it as i dont have the problemā¦ sorry. i have 3 routers in my house, all running openwrt. ;/
Iām having the same issues with the Wi-Fi connection just dropping the printer needs to be restarted to get it to come back. This was with 1.8.4 and now also 1.8.6. Iām using an Xfinity cable modem router comboā¦ seems crappy, but itās pretty reliable as far as Wi-Fi goes. The router just doesnāt have any good configuration settings.
Iām going to try this one that Iāve used on RaspberryPiās for a long time without any issues. It seems to work in the Cubieboard so far but Iāll update after a while to let you know if itās stable: http://a.co/3Qm6qP2
Well after a few parts, I havenāt had it go belly up during a printā¦ but I have had it go completely offline after a print was done a few times. Not every time though. It required a restart of the machine to get it back online. So if this keeps up Iāll probably switch to a RasPiā¦ but Iām kind of avoiding it for now just due to shear laziness in not wanting to disassemble the zimboard to desolder the USB connector. BTW has anyone tried to connect the hardware serial connection of the zimboard to a RasPi yet on the GPIO connector (kind of like the cubieboard has done)?
EDIT: just had a longer print completely lock up on me. Pausing and Resuming seemed to get it unstuck, but now the part has a nasty melty spot in it. I guess Iāll get un-lazy and do the octo-pi mods now 
hm, alright guys, let me play around with it for a bit.
Iām midway through another update, but iāll keep futzing with the wifi dongle. maybe updating kernel helps, as it should be a different driver set.
sorry for all the issues, it seemed to fix it for driph and others that tested it. will keep on it.
Maybe it helps if I said you that the problem seems not to be the WIFI Dongle. I do not have the wifi dongle installed at all, due my ZIM is in a wired network, but I also have the problems. Octoprint seems to crash or freeze for a minute or so. Itās not in every print, but sometimes itās even multiple times in one part
When it locks up, it doesnāt appear to be Wi-Fi, but there is definitely some other failure mode where the entire printer is offline until itās restarted.
EDIT: I had it lock up again, and this caused the extruder to jam for some reason. The ABS either crystallized in the nozzle or something else.
Interesting. As @waffles said above, my Zim has been way more stable since the last update. I generally run wired now because thereās cable right behind the printer anyway in its current location, but wifi was much more stable in general.
The latest waffles update, 1.8.6.
How do you install plugins and upgrade octoprint via putty?
I did it like this:
connect to the Cubieboard via putty with root / Longgang2014
- mount -o remount,rw / ;sets the filesystem rewritable
- /etc/init.d/octroprint stop ;stops octoprint service (which runs as user zim)
- ā¦wait a few secondsā¦
- /etc/init.d/ octoprint start ;starts octoprint service (this time as root!)
- ā¦wait againā¦
- open your browser and goto zim.local:5000
ā> octoprint takes very long to start, so dontĀ“t be impatientā¦ sometimes takes up to 3 minutes!
Due to you are logged into the filesystem as root and set it to rewritable, you can install plugins and upgrades. After a reboot, the filesystem goes back to write protected and normal user mode.
ā> I also did a lot of other modifications, so this MIGHT not work as intendedā¦ please let me know.

Hi Jayala. Youre on oem hardware, but youāre using octoprint, correct?
Its the same process for octoprint whether youre using the raspberry pi or oem hardware.
Have you solved the freezing issue with octoprint? I have the feeling that the more often I connect and disconnect to the web interface, the more often does the freezing and blobbing happen (kind of timeout of the web interface sessions?) But itās only a feeling.
I can see the blobbing in the time lapse video, but I havenāt yet figured out parallels to certain actions.
I read in a german forum that the cubieboard seems to have some problems with debian jessieā¦ maybe thereās a general problem with cubie?
Weāre still on wheeze not Jessie so Prob not it. Been a bit busy with other projectsā¦ Will take a look Iām running low on ideas though so any suggestions are good to look at
Ya that freezing issue is really weird. Its not as bad as it was in earlier builds of the firmware but its still there. It happens like every 3rd or 4th print.
I have flashed both my Zims, notes for thoes who have more then one. First you need to define you IP in the camera settings, I had both printers showing the same camera. Two you will need to use the IP to connect. I Love this Hack!
May I have a copy of the Cura config file, I want to take a look. your settings are very well balanced and fast.
Thanks.
For 125$ is this printer worth the buyā¦ i am more than capabale of flashing a sd card and modding a few things if need be
Has anyone got this to work? I still canāt get my octoprint to update. I followed the steps (I think) but no luck. I tried the update after it restarted and after I did an additional ārwā
Iām also having one other problem. On the control tab the tool select doesnāt work. I can see the dropdown for āTool 0ā and āTool 1ā but when I select one it goes back to āSelect Toolā. Which means I canāt extrude/retract manually. Not the biggest deal, but I started trying to upgrade to see if it would fix this. Any suggestions would be appreciated. Iām running 1.8.6 and 1.1.0.22
