**Justin Garrison:** Hello, and welcome to Ship It, the podcast all about everything that happens after you git push. I'm your host, Justin Garrison, and with me, as always, is Autumn Nash. |
**Autumn Nash:** Hi! |
**Justin Garrison:** That was a very quick hi. |
**Autumn Nash:** I always sound like a bird... I'm always like "I swear I'm not this squeaky in real life." |
**Justin Garrison:** On today's show we have Gina, who is the maintainer and creator of the OctoPrint project, which was not only an awesome time talking to her, and just learning more about how it started, but as a user of OctoPrint back in the day, with my printers, it was really fun just to see how all the things th... |
**Autumn Nash:** She was one of the most fun guests, because just everything she said was "I had this problem, and then this is how I solved it." She's an amazing problem solver. Gina is legit, guys. And the fact that she's one of the few people to really make it really successfully at being an open source maintainer t... |
**Justin Garrison:** And not just for a little while. This is for 10 years of a project, which is why it's cool. |
**Autumn Nash:** That's what I'm saying. Sustainably being the only maintainer for an open source project that is that widely used is amazing. |
**Justin Garrison:** Especially one that's not corporate-sponsored. She mentioned most of her sponsorships come from the community, not from companies. So if you look at something like curl, or these other projects that are used by developers heavily, it makes sense that a company might sponsor them a little bit more, ... |
**Autumn Nash:** That's what I'm saying, it's almost one of the most pure versions of what open source maintaining and crowdfunding, an example of how it can be done right. |
**Justin Garrison:** So let's go ahead and jump into the interview, and I know for the outro Autumn's making a game for me, so stick around and we will see how that goes. |
**Break**: \[03:33\] |
**Justin Garrison:** Thank you so much, Gina Häußge, for joining us on the show today. Can you tell us about yourself and how you got started with creating OctoPrint? |
**Gina Häußge:** Yeah, so you already said my name, but I'm also known as foosel around the world, and especially around the net... So if anyone has come across that name, then yeah, that's me. Hi. And yeah - well, OctoPrint. That happened basically when I got myself a 3D printer back in late 2012, and found myself in ... |
I threw it on GitHub up, and within a week or so the emails started coming in, and the feature requests started coming in. Then it took over my life, and now I've been doing it full-time for almost 10 years, and crowdfunded for -- wait, we do have 2024 now, so that must be eight years, I think... Yeah, eight years full... |
**Justin Garrison:** That's awesome. That's one of those success stories of open source and crowdfunding. That's not a common thing, where it's like "Oh, one person started a project, and now you can actually make your living off of this hobby, or originally hobby sort of thing." That's really awesome just to hear that... |
**Gina Häußge:** Yeah, and it's always something that I can talk about at parties, even if people don't know what 3D printing is, or what open source is. If I tell them people give me money even though they don't have to, then I always get interest from people around me. \[laughs\] |
**Justin Garrison:** 2012... What printer was even available 2012? That's like the CNC cupcake machine. |
**Gina Häußge:** In my case it was an UltiMaker that was - yeah, a big, wooden box. No heatbed... |
**Justin Garrison:** Yeah, no one even knew what to do there. |
**Gina Häußge:** Very slow, and very weird... And the filament was still thicker... Like, it printed with the three-millimeter stuff, which actually was 2.85 millimeters, but still, yeah, almost twice the diameter of what we use these days, mostly... So 1.751. |
**Justin Garrison:** It's like melting crayons. |
**Gina Häußge:** Yeah. \[laughter\] It was weird when I got my first roll of filament, of 1.75-millimeter filament in my hands; it felt so weird, and not good, and like it would break just by looking at it and such, because I was just used to all of this 2.85. And then I think last year or so I threw out all of the old... |
**Justin Garrison:** So in 10 years of OctoPrint, how many printers do you support? It seems like it grows every time I check it out? |
**Gina Häußge:** Yeah, so the thing is that most printers out there actually run on open source firmware, and have more or less agreed on a communication protocol. I say more or less, because a lot of the printer vendors actually adjust the firmware, often without really knowing what they are doing, with the result tha... |
\[12:07\] And that way - yeah, pretty much everything that is old out there is supported by OctoPrint, but these days it's a bit more tricky, because a whole bunch of printers are now currently coming out that have a full-blown host system... So OctoPrint is a so-called printhouse, and a lot of printers now come with s... |
