Unfortunately, having these two printers tied to my desktop was becoming an issue, because I want to keep my office cool, but the printers perform better when it's uncomfortably warm, and enclosures didn't seem like the right option. I also have a couple of 3d printers: a Prusa Mk3S as my primary, and an Ender 3 Pro that I got off Amazon a few months ago to have as a cheap secondary. I think that because of that I couldn't get the latest RetrOrangePi build working on it, and just getting the composite working with a cheap backup display was a real pain in the ass, so I thought about re-tasking the boards for something else. The original "Zero" only has composite out, not HDMI like the "Zero Plus 2". It also has a tiny footprint, built-in USB hub, etc. It has the same chip as the Banana Pi Zero M2 (AllWinner H2+), which is much more powerful than a Raspberry Pi Zero. I had picked up a half dozen OrangePi Zero boards on AliExpress with the intention of using them for some cheap, portable retro consoles in combination with some composite backup displays.
For about $20, you can upgrade your 3d printer with wifi, ethernet, a web-based management interface, and still run it all off the single power cable that your printer came with, and without soldering anything.
