This week we are offering you a new guide on how to manufacture your 3D Printer wireless. This is a Medium ability level guide.

Have you run into this problem?

You want to 3D print a thing that can take several hours, but you in addition want to use your desktop for other things. Figuring out how to solve this problem only got easyr.

I’m going to show you in this guide how you can, for around $45 dollars, manufacture your 3D printing device wireless, and how you can obtain notifications when the print is done. If you have an old webcam lying around, you can actually see what your printing device is doing of any Internet connection…how rad is that?

Let’s get into the detail: Many 3D printing devices work on a serial over USB connection to stream commands to the 3D printing device. This is easy and straightforward, but yet there are many things that can go wrong:

  • Your desktop can go to sleep
  • You can jiggle the cable a little bit and interrupt the connection
  • A demanding program on your desktop can cause a hiccup in the print system
  • You require to access your desktop for other works but it’s tied up with this print run

Even yet many 3D printing devices have an SD card function, you yet have to walk over to the printing device, and enter the SD card in…and if a thing goes wrong, or if you want a notification when the print is done, via an SD card is not the many solution.

Wouldn’t it be really great to only have the printing device do it’s thing while you can do yours? We ponder so that and this short free guide can show you how.

First, you want to manufacture certain you are via a 3D printing device that does not require any proprietary control software to run

Second, you can require to purchase a tiny Linux desktop called a Raspberry Pi 3 for around $35, a power donate for around $10, and an 8GB micro-SD card with adapter for around $10. Many of you can may already have these items at home, and this system can work with virtually any Raspberry Pi edition, as well with many micro SD cards. There is a benefit to via the new Raspberry Pi 3 for the reason it may already has WiFi is on-board.

Here are the basic instructions that can get you up and running a wireless-enabled printing device in of 30 minutes:

  1. Download the open-source print control software, OctoPi of octoprint.org and unzip it into an IMG file.
  2. While that is downloading, there are a couple of other pieces of software that you can require to use.
  3. Download Win32DiskImager of https://sourceforge.net/projects/win32diskimager/ for you Windows users…for Mac, there are instructions on the OctopPi website that can assist you install the image file on the microSD card.
  4. Do a Google search for “Bonjour for Windows” and install Bonjour on your desktop. If you are running Mac, this is may already installed for you. You don’t have to do this step, but it manufactures it easyr to log into the Raspberry Pi later on.
  5. Insert the microSD card into your desktop (via the adapter if requireed) and run the win32diskimager program, identifying both your micro SD card and the IMG file of OctoPi. Write that image to your microSD card.
  6. Your microSD card can show up as a new drive on your desktop…before we get to the Pi part, we want to get wireless pre-working. Navigate to the root of that card and open octopi-network.txt in Wordpad (be certain to use Wordpad, as notepad does not format the text correctly)
  7. Remove the hash mark at the beginning of the three entries that correspond to your network setup, and enter in your SSID and password and save the file.
  8. When that is done, remove the SD card of your desktop and insert the microSD card into the Raspberry Pi 3.
  9. Connect the Raspberry Pi to your 3D printing device via the USB cable.
  10. Power up the Raspberry Pi and wait a couple of minutes or so.
  11. If you installed Bonjour earlier, navigate to octopi.local in your web browser and you can see Octoprint. If you did not install bonjour, and so find the IP address that the Octopi grabbed, and log in that way.
  12. Once you have turn it intod a few decisions that Octopi asks you of access control, go to Settings and identify the baud rate at that your printing device runs. So edit the printing device profile to manufacture certain that the dimensions of your print bed is listed accurately. This is not strictly requireed, but it is really great for visualization.
  13. Now go into your slicing program, slice a 3D version and turn it into a GCode file.
  14. Upload your gcode file to your Octopi server and click print, and you are done!

There are additional add-ons for Octopi that allow you to use a webcam, get notifications, and additional, only appear in the settings menu to see what is may already installed, and what other add-ons you can want to use.

Thanks for watching this Raspberry Pi video blog and come back following week for another guide of HoneyPoint3D!
