Can somebody help me with the wifi issue I'm having?
I'm trying to setup octoprint but my built in wifi on pi 3 won't connect to my wireless access point.
I uncommented corresponding (WPA/WPA2) line and inputted correct SSID and password on octopi-network.txt
I tried both stable and nightly and no luck with either one.

I tried ethernet connection and it's fine, and when I install latest raspbian my wifi works fine.

Device:
-Raspberry Pi 3
-Airport Extreme (router)
Software:
-Latest Stable and Nightly (tried both)

One more reason, why I am a proud patreon of +Gina Häußge. 2 Mouse-clicks and i can swap between different configurations with ease. #octoprint made this possible. Thanks!
 
One of the many reasons I use #octoprint for the DICE is this:

I make mistakes some times and upload an .x3g file instead of a .gcode file and these .x3g files seem to get stuck in the file list and I cannot delete them :-(
Solution? please.

I would like to develop a plugin to control my LED light connected to the pi. I can do it in python not a problem. Works fine for now. Now I wanted to create a proper octoprint plugin that might be used by others as well...

I have 2 questions (general plugin implementation, guess):
- Where would I be implementin and how a button to turn on / off the light (e.g. in the control tab or I was thinking in the navbar. I understand how to add content to the navbar / html / jquery content. But how would I call a python function (light_on()) in my plugin. Would I need to do that via api call? Blueprint? Any suggestions where to start?
- I was also planing to integrate a rotary encoder to contol the duty cycle of the LEDs... but this would require constant checking of the GPIO pins and calculating the delta. Would I be required to create a seperate worker thread / Q to get the values into the plugins main thread? Or Maybe a on_pin callback? Any other suggestions ?

Thank you for your suggestions!

Okay, I am almost there. Works great. templates, js, python. I created a github (https://github.com/MartinBienz/OctoPrint-MyLight) for it, released it, downloaded and installed. Want to do some "long time" testing. Cool stuff, learned a ton! Thanks Gina.

I've recently upgraded my Octopi installation to a Raspberry Pi 3 and I have yet to be able to connect to the wifi network with the Pi if I have Octopi installed. I'm using the 1.13 image and I go through the install, setup my network in the appropriate files on the sd card (both the default one and the one if you want to use multiple networks) but when the Pi starts up it's never connecting to my Wifi.

I've tried with both the internal Wifi and a dongle that I use on my Raspberry Pi 2.

If I install the default Jessy image (without octoprint) it connects fine with both the internal Wifi and the Dongle.

Ok, I got mine working. Basically something is wrong with the octoprint-network.txt either with the textedit program in Mac OS X, or with how it's loading. I followed these instructions: youtube.com - Octopi Raspberry Pi wifi not working work around I commented out the source octopi-network.txt, then added my network information into the wpa_supplicantl.conf file, rebooted and now it connects just fine using the default wifi adapter built in to the raspberry pi 3. It was identified as issue #266 on the Octopi github

I was wondering if anyone is still interested in the FlashForge Dreamer, I have a PowerSpec Ultra which for the most part is the same printer. I have the ability to get usb packet captures for the device at various stages, and am willing to do some further digging into the protocol. Would this data interest anyone out there?

Due to the limits of the serial connection (115200 baud) from octoprint to my prusa i3mk2 I came up with an idea on how to create a workaround for this.

My question to you: Do you think this would be doable with a plugin ?

Via octoprint im currently limited to like 40mm/s and sometimes the serial can´t catch up with small structures even at this low speed. The printer can do quite a bit faster from the SD card. Transferring gcode via serial to the SD is out of options for the same reason - speed. Since the printer has build-in support for wifi-sd-cards (just one brand currently but it is what it is) and these cards allow to create a share on the network i came up with an idea.
I´d like to keep my workflow as simple as it is - I´m using slic3r to send the files directly to octoprint - moving around with sd cards is sooo 2016 ;-).
My idea would include octoprint as the interface but instead of printing from the raspberry or sending the gcode via serial to the sd-card I´d like to have octoprint copying the file over the network to the wifi-sd-card, checking the file (checksum, size, whatever) and starting the print from there.
I´m aware that i loose the functionality of the gcode viewer while printing and the timelapse per layer - but I´ll gain speed and accuracy without loosing the ability to make "timed" timelapses and the overall control of octoprint. This way would also allow to start a new printjob while the raspi is still rendering the timelapse from the print before – this could also allow one raspberry to control multiple printers maybe.
Making the serial faster doesn´t make as big of a difference as show here: https://www.youtube.com/watch?v=SBZ7MfvAsGc

Tl;dr: serial printing too slow, transfer of gcode too. Use wifi-sd-card and transmit gcode over the network and start the print via raspberry.

Please give me comments and maybe a response if this could be done with a plugin or does this require mayor changes to octoprint.
And thanks for providing this awesome piece of software to us. Keep up the good work. Richard

On Marlin it is a simple define. On Octoprint I cannot find the value anymore (code changed to much in the years)

Would it be possible to make the confirmation box optional when cancelling a print. It is anoying the shit out of me. I wouldnt have hit the cancel print button if I didnt mean it, and it is slowing the time from hitting cancel to it actually stopping the print. Most times I'm having to turn off the power to the printer because its so slow and this unessesary addition is adding to the time it takes to stop.

Hmm did exactly that adding gcode in under cancel. But when cancel button was hit, the printer just stop there

For users of the new Cura (2.3.1) and OctoPrint, I've made an OctoPrint uploader plugin. There's no installer, but to install it just needs to be unzipped to the right place.

For those interested, it's here: https://github.com/markwal/Cura-OctoPrintUpload

I need a bit of help logging in to octopi.

I installed it yesterday (latest release) on a new Pi3 using the posted steps and followed up with Tom S.'s instructions and all went well - booted, logged via putty, ran raspi-config and expanded my ssd card. Ran Octoprint and did the suggested updates. I set it up with a fixed IP in my router (don't care for Bonjour) Added a camera, saw the stream on my browser. All perfect.

Then I unplugged, set it up to watch my printer (not connected to printer, yet), powered up again and had problems. Octoprint server seems to run OK - I can connect through the browser. But I can no longer log in to Octopi. Putty gives the login screen and when I log in as pi and give the password, the prompt never returns. Eventually putty disconnects with "Software caused connection abort". If I give the wrong password, I get the "Access denied" prompt and get to try again (forever, it seems) but the second I enter the correct password, the session hangs. (tried from all three of my Windows 10 PCs.

During all this, Octoprint still runs OK.

I've started over -- re-imaged the SSD -- with the same result except now I can't expand the SSD since I can't log in to run raspi-config to expand the filesystem, so my use of Octoprint will likely be a bit limited.

Any help would be much appreciated.

For those following the saga, I've fixed the problem. I'm not sure how it made any real difference, considering the symptoms, but I replaced my aging TP-Link router with one that's relatively new - ASUS RT-N66U. Worked immediately.

Thanks, again, Gina, for the extended help. You can add this one to your list of possible solutions to an obscure problem.

So I guess Octoprint sends data over the Internet even when it isn't open. Is there anyway to leave it connected to the local wifi, but have it blocked from sending data over the Internet because I have a cap and it is eating up my data.

Hi, I can install raspbian or noobs, but it seems I cant install any octoprint release on the SD Cards, it just doesnt boot (ACT led not even flashing). But like I said, it work everytime with any other install. Tried to redownload the files about 10 times and it still the same thing. Any clues on that??

Thanks

What is the MD5 value you're seeing so I can check if you're using the same image as I am.

+Gina Häußge How do you feel about people referring to OctoPrint as OctoPi? Wonder how you feel about it, as I recently got in a small argument about it, and me trying to protect your credit as the creator, insisted they refer to it as OctoPrint when making instructional videos. Wondering if I overstepped my bounds, or if you even think twice about it? Thanks!

Find a popular youtuber to put out an official tutorial on how to install it, what it is, what it isn't, and most importantly to scream at people who call them the same thing.

Use Etcher to save the zip image to a SD Card... Much easier than to fiddle around with command line. Available on Mac, PC and Linux. Couldn't be easier.

Have a problem with my webcam in Octoprint 1.3. It only streams to the control tab if I manually run /mjpg-streamer/start.sh from an SSH session. Once it is running everything works as it should, but the script dies once I disconnect from the SSH session. Anyone have an idea how to resolve this?

That's how stuff under linux works, unless you detach your script from your SSH session (e.g. through nohup, see en.wikipedia.org - nohup - Wikipedia for example) it will stop when the parent session exits. Look into setting up an init script (there should be an example in OctoPrint's wiki) to have it start automatically, and detached from any SSH sessions.

Using or converting RTSP-Stream

Hello fellas,

I have an Xiamo Ants "hacked" to get the RTSP-Stream, but the OctoPrint only supports MJPEG. It is not possible to change that on the webcam itself.

Is there anyone who worked out a workaround like converting it through RPi3 its processor with ffmpeg or smthg? And did it work?

Would appreciate, if someone could help, thanks!
