3D printing with Cura on the Raspberry Pi

Since I had a bit of time on my hands, I spent some time this weekend switching over the software I was using for 3D printing. Since I first got my 3D printer 5 or 6 years ago, I’ve been using Repetier under MS-Windows. This is a very flexible solution but its Raspberry Pi implementation is only as a server that you would access over the web which is nice, but you can’t see the model progress while printing. I’ll need to experiment with this more though.

There is a Cura implementation that ran on top of Octopi. This print controller will allow me to transfer information directly to the printer, initiate printing and monitor it remotely over the web. Here is the main interface:

One added bonus of making the change to Cura and Octopi is that I can monitor the printing process remotely using a USB camera (that I had lying around) — this capability was just built in. Here is what that looks like:

The first 2 prints I tried came off flawlessly, though I do have a small X axis offset issue to center the print that I’ve yet to resolve.

If you have a spare Raspberry Pi lying around it is definitely worth looking into. I also want to try using Slic3r on the Pi as an alternative 3D slicer.
