I’m running the nightly devel build from (OctoPi Downloads). Devel has some nice features I make use of
Forgetting all about your 3D printer for a minute:
Download the latest version of Raspbian from the Raspberry Pi site. Boot into the GUI (using startx). Load up a browser. Go to a webpage.
If you can’t do this, then you have a hardware issue which none of us will be able to troubleshoot. Please let us know if this works.
Slipvelocity are your suggesting I install Raspbian with out Octopi? If so how to then install Octopi? Or is your plan to just see if the stand alone version of Raspbian works as expected on my network. IF so makes sence.
Please clarify.
I am pretty sure he just wants to make sure that just the normal operating system will work to make sure it’s not a hardware problem with the raspberry pi or networking.
Hey guys Im getting back to this RPi issue, had to drop it for while and focus on dead lines.
The update is I reformatted the SD card and reinstalled octopi OS (same one as before). Before I reinstalled the standard Raspbian OS as suggested by slipvelocity I figured I would give it a try and try to set up the RPi this time using the WIFI adapter for the RPi and see if it would make a difference. BUT now I can not log into the GUI in order to set up the Wifi settings. When I type in startx it seams to start logging in, text screen scrolls up, then screen goes blank and nothing, screen is black and goes nowhere.
I contacted the company I bought the RPi from and this is what they said to do to log into the GUI. BUT I have no idea what they are talking about as far as what and were to type in to get to the GUI. I tried to type in raspi-config, config, etc but gets me no where.
Can someone walk me threw this? tell me exactly what to type and were.
Letter From CanaKit,
Hello Bill,
Normally the command startx will launch the GUI, so there may be an issue in the installation or there is data that has been corrupted or there is an issue with the Raspberry Pi board itself (less likely scenario). Alternatively, you may try to go to raspi-config and navigate to boot_behaviour and hit enter. This will allow the GUI interface to start automatically. Please let me know if this helps or are still experiencing an issue.
Thanks & Regards,
Medi

I am almost positive you have a bad/corrupted OctoPi image file. I still recommend you download the Raspbian image and make sure your hardware works, and if it does then re-download the latest OctoPi image (stop using the one on your hard drive that is corrupted).
Ok will do. I contacted the company I bought it from to request a new preinstalled SD card. Wonder of they will send me one free of charge or if they will make me pay for it.
I only skimmed the thread, so my apologies if I repeat something already mentioned. I agree that your next step should be to re-download Octopi, then re image your SD card. (As already mentioned putting plain Rasbian on there first, just for testing, would be ideal.)
Below are some things to lookout for that have caused various problems that usually showed up at/around boot time or when I first put a load on the system (e.g. startX).
I’ve found that you always want to do a “full” format (i.e. write all zeros to the SD card) EVERYTIME before you copy a new image. Strictly speaking it shouldn’t be necessary, but in the real world SD cards play by slightly different rules than a traditional hard drive. It may work without this step, but definitely it’s worth the extra time to do a full format. (You’ll even get better performance, at least in the beginning, if you do a full format first.)
On the same note, all SD cards are not created equal. You definitely want a high quality card. It needs to be fast, but more importantly it needs to be reliable.
(Note, the below is mainly written the higher power demands of the Pi 2 Model B in mind. However, many, if not all, of the same points still apply to the somewhat lower current demands of the Pi Model B+.)
Also take a look at your the power adapter and power supply you’re using for your Pi. The only reliable way to provide full power to a Pi 2 Model B is with a “dumb” adapter. By “dumb” I don’t mean the cheap from who knows where that happens to say the output is 5V. I mean a high quality adapter that doesn’t try to manage the output voltage and/or limit the current it provides. USB computer ports and “smart” chargers (e.g. for a cell phone/tablet) will NOT provide 2000mA of 5V power if they are properly designed. A USB 2.0 port on a computer will only provide 100mA of power. Worse still, many smart chargers are designed to step their voltage down further and further under 5V as load increases.
However, your mileage may vary. More recent USB charging specs seem to be more friendly toward the power requirements of the Pi. And/or it’s not uncommon for manufacturers to disregard the official specs and do whatever it is that they do.
Another thing that makes any micro USB adapter you have lying around more likely to work–even if it is a “smart” adapter. Is that the Pi doesn’t always need the full 2000 mA of current. Not counting any power draw from USB devices or GPIO pins, it looks like 1500 mA would be sufficient to power the Pi. And 1500 mA is one of the magic numbers for “unconfigured devices” in one of the more recent USB charging spec revisions. (The Pi says to use a 2000 mA supply because that is what it’s self-resetting fuse is set to trip at. A power adapter larger than 2000 mA* would not give you more power to downstream USB devices/GPIO pins.)
My personal experience is that I could not power my Pi 2 reliably from any of my “smart” chargers that came with phones, even those rated for 2 A. However, I was able to use a 1800 mA power supply that originally came with another “USB powered” device. And don’t forget about the USB cable itself. I have more than one cable that can’t carry enough current to run the Pi.
If you see the “rainbow square” icon ever so up in the display when you have monitor attached, you know for sure you have power problems. Under voltage/under current problems probably aren’t going to cause any sudden catastrophic hardware failures. But they sure will cause all sorts of weird things to happen. If you’re lucky it’ll just cause a kernel panic or freeze the system. Corrupting memory and then the SD card/file system are also common.
\
- If you are out shopping for an adapter, you may look at one that says it can produce more power. Say 5V 3000 mA. This is because even though the adapter’s output is rated at 5V, 2000 mA it doesn’t mean it will be 5V when providing 2000 mA. (Unlike some “smart” adapters that do this intentionally, it’s often the case that cheaply made adapters don’t live up to their rating. At least to what one might commonly assume the ratings mean.)
An update to this thread for anyone who cares to know. I was able to get back to the RiPi / Octoprint set up today. 1st I confirmed the RPi hardware was ok. I had the company send me a new SD card with Noobs on it and it worked fine. As per many of your suggestions several weeks back I downloaded the Octopi image again and started over with a reformatted card and the latest version of Octopi ( a different copy then I was using before) Everything is working fine now and as expected. The problem was defiantly the Octopi image I was working with must have been corrupt.
Thanks to all of you who tried to help.
Hooray! I’m happy to hear this, even though it’s been months. My only current complaint with OctoPi is that sometimes I have to hit refresh 5-10 times on my iPhone before the webpage will load. Not a huge deal, but annoying. Other than that, it works splendidly.
Kind of off topic but does anyone have any recommendation on where to get buy the Raspberry Pi. It looks like the B is the most current version (not B+). I wanted it to run prints with my AO-101. I would like to have it on wifi and get camera too.
Do I need a starter kit? If so which one. I can print my own case but it looks like you need certain power supplies, cameras and wifi dongles.

Adafruit?
Amazon? (I have a prime membership)
Any advice on what I need to get setup and where to buy would be appreciated.
Microcenter offers competitive pricing if you want to pick it up locally.
You will need a USB micro cable and USB port (power supply). An SD card is also required for storage, >4GB is preferable. Networking can be achieved by either the onboard ethernet jack, or a USB WiFi dongle.
I am like the OP I just ordered a complete kit from CanaKit, Pi 2 B, PS and etc so I hope it all works. When my wireless Logictech keyboard and track pad combo comes tomorrow I will give it a try. I think the price on the whole kit was $69 from Amazon and then I ordered a breakout and breadboard kit for another $14. Free shipping with Prime of course.
Its been a long time since I have played with anything Linux, should be interesting. I am wondering if the entire SD card was bad with his kit, corrupt Noobs and all.
Thanks Mirage335
I picked up one at Microcenter (they are on sale so about $10 cheaper than Amazon). Everything else I ordered thru Amazon and some how got same day delivery at no extra charge.
I had some problems setting up the wifi with EDIMAX adapter so I found Youtube video which showed how to set it up.
Hey all, having some trouble getting my pi 3 up and running correctly. Since i’m new to both the pi and octoprint i’m running a bit in the dark, but i’m a linux user, so i have the basic skills to troubleshoot and fix things usually. I’ve tried using the latest nightly build of octopi since apparently the pi 3 is so new that there is not yet a stable build for it. Some people said the nightly builds work fine on a pi 3, but that was awhile back and now some say they don’t.
Having formatted my sd card and imaged the latest nightly build the pi seems to boot up and get running. I am able to ssh into it from my machine, but when i tried the web browser it didn’t work. Using the shell through ssh i am able to troubleshoot a bit. Trying to run octoprint manually and/or running various commands to see if it’s even running seem to show that octoprint is not running. Someone also said to check my router to see if it shows up in the device table (which i also needed to figure out it’s ip) and instead of having a device name of “octoprint” it has a device name of raspberrypi. Just a wild guess at this point, but maybe someone goofed and the current nightly build is not for octoprint, but instead is a default raspberrypi image??
Browsing through the sd card folders manually there does seem to be folders with octoprint stuff in them, but apparently octoprint is not running by default. Also, i guess it doesn’t matter until octoprint is running, but there is no wifi text file in the root folder for me to configure the wifi settings.
Perhaps i just need to wait for a stable build, but there were others who said they already had pi 3’s up and running with their mini’s.
Watching the github issues, it seems a few of the recently nightly’s didn’t have Octoprint on the image… Try downloading the most recent copy of the nightly.
good to know. I’m pretty sure i’m using the latest. I suppose i could try an older one, but i’d be kind of guessing. Perhaps i’ll just wait until a new one comes out. It’s ironic that they call them “nightly” builds as more recently they look to be weekly.
Hi Biolumo
OctoPi 0.13 is out and (as per release notes) ready to run on a Pi3
All the Best
Frank
It works great on my Pi 2 now that the desktop is gone, so I setup a Pi 3 and an old TV in the work room so I have direct control of the Octopi interface without having to shlep in my laptop.
Let me add my suggestion that all Octoprint users go support the project, even at $1/month. That’s less than 1/3 a cup of coffee, or about the cost of 2 Roctopi’s (is that the plural?). Darn cheap to let me print and monitor from any room in the house.
On that note, Please think three times (not just twice) before attempting to put octoprint on an internet-accessible machine. Unless you’re very good at both locking it down initially, and maintaining that on a regular basis, there’s serious risks. This isn’t like having someone steal your iTunes files - a malicious actor could easily destroy the printer, and even potentially burn down the house. Or put it another way - I’m a security architect with the world’s largest InfoSec company, and my octopi is nicely snuggled behind my fire(wall), all set for a long nights printing. IMHO (and that comes with two grains of salt), it’s not worth the risk.
