"If you found this video and have not watched part 1 then please stop this and then click Go back and watch part 1 and come back here. Because we are going to continue on as if you watched part 1 you missed out on ALLof the Explosions! and fun stuff ♬ DANCE MUSIC ♬ Welcome to Joe Geek! You should now be all set to continue setting up your OctoPrint server. Here is the list of parts you will need before continuing (see part 1 for more details) Hardware: Required: 1. Raspberry Pi 3 2.

Micro USB Power Adapter 3. MicroSD 4. USB cable to connect to your printer Optional: 1.Wireless Dongle: 2. Webcam 3. Printed Pi 3 Software (WinOS) 1.Octo-Print 2. Win32Imager 3 Putty 4 Notepad ++ (Optional) Lets begin with setting up the connections to the Raspberry Pi. (Do not power up yet, do the first steps first) Install OctoPrint on the microSD card.

This is how we get the Octoprint on the SD card. Its pretty straight forward. 1. Open Win32 Imager 2 Locate where you downloaded the iso file from OctoPrint. 3 Place that location in Win32 Imager and hit install. This will take a few minutes as it wipes the card, makes it bootable and then installs OctoPrint as the OS. Configuring Octoprint BEFORE starting 1. With the card finished in Win32 Imager locate it in File Explorer.

Open the disk and look for a file called Octopri-network.txt. Use Notepad ++ or another true text editor. 1. If using the wireless Adapter then look for the network type you have setup: WPA/WPA2 is what most routers are these days by default. Uncomment out these lines by removing the pound sign (hashtag) iface wlan0 inet manual Wpa-ssid “Put ssid here” - Here is where you put in your network SSID inside quotes Wpa-psk “put password here” here is where you put in your network password. That is it, save the file. You do not need to edit it if you are using ethernet, it finds that automatically, unless you have a specific network setup.

1. Remove the card. Firing up your Pi for the first time: Once you have installed OctoPrint on the card then proceed with these steps: Step 1. Insert the microSD card in the bottom side of the Pi. Older models use standard SD cards. Step 2. Insert either Ethernet connected to your network or if you purchased a USB Wireless Dongle, insert that now (hehe) You can use either or at this point. Step 3. Insert USB into both your printer and one of the USB ports on the Pi Step 4.

Insert webcam into one of the ports (optional) Step 4. Power up the Raspberry Pi. Once the green status light goes solid then you are all set. If it wont connect or the lights are giving off an error, unplug it and redo the steps for writing the iso file to the card. Connecting to your Pi On windows search bar located at bottom of your screen type in CMD. When the program called Command Prompt appears on the list of programs, right click it and then select Run as Admin. Type in: Ping octopi.local If it returns with a TTL time then you are all set.

If it times out then you either need to reconfigure the network again or reboot the Pi. Copy down the IP address for later You can also see if it is in your network by looking at Windows Explorer and in the Networks Tab look for something called Octoprint instance on Octopi. If you find it there, right click, go to Properties and copy the IP address. You will need it for the next step. We are almost done with configuring. Connect to the Pi with Putty: Open Putty and put the host name as either octopi.local or the ip address you just wrote down. Leave the port at 22. Hit Open on the bottom Putty will freak out at this point saying there is a security exception.

Hit yes to accept the fingerprint. You will now see a console window pop up with a green cursor. Ahh the good old days of green cursors…. Login for this step is the default: Login: pi Password: raspberry Now it should let you connect to pi@octopi ~ $ <- that is the prompt on linux Type in passwd to open up the Password changing utility Put in the current password: raspberry (nothing will indicate you are typing) then hit enter Put in a good strong password 2x then you are done when it says updated successfully Next step: at the prompt put in sudo-raspi-config and hit enter This will open up an old DOS style box that you can do a few commands by highlighting and hitting enter The most important one here is to Expand Filesystem- this will utilize the WHOLE SD card to be the file system.

You can also enable camera here as well. Select Finish and it will ask to reboot - say <Yes> and let it reboot You will get a connection time out warning now because Putty has disconnected from the server. Give it a moment to reboot and then lets move on. Now we get to the good stuff! Open up the web interface for Octoprint. Open any web browser other than Windows Edge (that is not a real browser). Chrome or Firefox will do. Go to (ip address or Octopi.local (I had trouble with this so I just used my ip address from before)) You should see the octopi web page as shown here.

First time you get there it will want you to make an account. This is not the same login/password that you used to setup Pi, although it can be it doesnt matter as long as it is a secure password. Follow the instructions and select Keep Access Control Enabled unless you are on a 100% private network. If your network is connected to the internets then you must use Access Control unless you want people digging around in your network printing out nasty stuff on your printer. Reload the page and login Now you can set up your printers specifications, check out the webcam, drop files directly onto the page and the built in Cura addon will slice it for you. You are done! Enjoy your new web enabled print server! Well done.

Transcript from Extruder Joe:

"Do you have a 3D printer? Do you find that you end up carrying these files from your computer Over to your 3D printer about 1000 times per day? via sneaker net? Well today on Joe Geek we are going to cover something called "Octoprint" On a little microcomputer called a Raspberry Pi I am going to show you how to get it setup and get it running in no time. Let's go! ♬ Dance Music Playing ♬ Hello everyone and welcome to JoeGeek - So what is Octoprint? Why Do I want it? What will I need to set it up? In this 2 part series we will go over all of these in turn so that you can have a powerful tool in your 3D printing Arsenal.

In part 1 we are going to get everything you need to get this going. Part 2 we will do the actual setup. To discuss Octoprint we first have to talk about the platform it runs on. It runs on Raspberry Pi. What is that? The Raspberry Pi is a series of credit card-sized single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer science in schools and developing countries. What makes it so great is it can run many different operating systems, including Linux which is what we are going to be running with Octoprint. Why do I want it? Currently the 2 main ways you can run your home or even business 3D printer are 1.

Keeping your printer tethered to a personal computer or laptop for the entire run of the print. If the PC has an update or powers off the print will be lost. The other way is you have to carry the print file over to the printer via your feet and put it in the printer, start the print and keep an eye on the print to make sure it does not fail. How does Octoprint fix this? Well it is a web server, contains Cura, a powerful slicer built right in, and also allows for connecting of a webcam. Watching with a webcam means you can watch your print instead of sitting right next to your printer, but instead from the comfort of your bed at 2am because you're paranoid its going to fail.

What will I need to get this going? Just a few things and a little bit of time and super computer skillzorz, just kidding… follow along to see. Pause the video when you need to. Links to all of these parts, file and stuff will be down below in the description. If you use Amazon links in the description it helps me out a ton, and costs you not 1 penny more. Thanks! Open up Amazon, order this stuff and while you are waiting for it to arrive get the software you will need for this. If you already have an old Raspberry Pi you can skip ahead in the video.

Raspberry Pi 3 Version B - As of today this is the latest, greatest and mostest bestest version of the Pi around. It contains a Broadcom BCM2837 SoC running at an eye watering 1.2GHz 64 bit Quad Core ARM Cortex-A53 Processor with 512KB L2 Cache… omg I just drooled on myself. A micro USB power adapter (this is how you power the pi) At least 8GB MicroSD chip (if you dont have one laying around go for 32GB EVO - they are fast and cheap as…. chips… ahem.) This will be the “Hard Drive” for the Pi and you won't take it out. The more storage you have for the files the better.

If you do not want this to be on an ethernet connection you will need a wireless USB dongle (hehe). Any will do but this one here works well: Webcam - This is NOT required but it does make a great addition to your print server. This is for a Logitech C920. Its a bit overkill but its what I own and cannot verify it works on other webcams. I hear it does support many of the top webcam manufacturers, buy at your own risk I guess. The C920 looks amazing and is being replaced in the next few years with a newer flagship webcam. That is it for purchases: More Stuff: If you want a case for it you can print one out later (or while waiting for the parts to arrive) from Thingiverse: I am going to be setting this up on Windows 10.

There are other guides around for Mac OS and other OS’es Software required: OctoPrint - Octoprint is the web server, printer controller that will run on the Raspberry Pi Side note: Consider donating to help keep OctoPrint running. They lost funding and are doing entirely through donations. Win32 Imager - You will need this to install the Octoprint Putty - Putty is a free software package that allows for secure connections on a network. Ok that is all of the things you will need for getting this project going. Head over to Part 2 for how to set it up. Please give me a like and subscribe! A comment would also be helpful if you feel so inclined.

Thank you all for watching! On to Part 2. ..."
