But as I was about to find out, reality doesn’t always agree with the documentation. Everything I read online told me this wouldn’t be a problem for the Pi Zero, especially since I could turn off the HDMI port as it would be running headless. I was specifically interested in low current draw, as I wanted to run the Pi directly off of the expansion port of the Printrboard, which I knew had a 5V regulator that’s only rated for 300 mA.

My research told me that the Pi Zero wouldn’t have the zip of the Pi 3 when it comes to slicing STLs, but that didn’t seem like too bad of a trade-off given the small size and reduced power consumption. At $10 it’s pretty hard to turn down the Pi Zero W as an OctoPrint host, so that’s what I decided to go with. While OctoPrint can run on pretty much anything, the Raspberry Pi appears to be the platform of choice for most people. Perhaps most importantly, I knew there was plenty of room available in the base of the machine so I wouldn’t have a problem fitting additional hardware in there. I picked up a used PrintrBot Play online because it had a small footprint (I could put it up on a shelf when not needed), all metal construction, and automatic bed tramming so I wouldn’t have to fiddle with re-leveling the bed after moving it around. Whether I “got it” or not, I was about to dive headfirst into the world of OctoPrint. It would be like when Scotty tried talking into the computer’s mouse in “Voyage Home”. I couldn’t control them both from the same machine, and while I could print from SD on the second printer if I really had to, the idea seemed painfully antiquated. What do I need to control the thing over WiFi for?īut things got tricky when I wanted to set up a second printer to help with speeding up larger projects. If I’m sitting at my computer, I just need to rotate my chair to the right and I’m at my printer. The majority of the things I print are of my own design, so when setting up the printer it only seemed logical that I would have it connected to the machine I’d be doing my designing on. I was happy enough with my single printer connected to my computer and controlled directly from my slicer over USB. The project has become so popular that the new Prusa i3 MK3 has a header on the control board specifically for connecting a Pi Zero W running OctoPrint.Įven still, I never personally “got” OctoPrint. Thanks to a thriving collection of community developed plugins, it can even control other hardware such as lights, enclosure heaters, smart plugs, or anything else you can think to hook onto the GPIO pins of your chosen ARM board.
Created and maintained by Gina Häußge, OctoPrint allows you to turn an old computer (or more commonly a small ARM board like the Raspberry Pi or BeagleBone) into a network-accessible control panel for your 3D printer.
If you’ve been hanging around 3D printing communities, or reading the various 3D printing posts that have popped up here on Hackaday, you’ve almost certainly heard of OctoPrint.
