Spent all weekend assembling this Core One. It probably took 14 hours in total. 12 hours to build and 2 hours to troubleshoot issues. Broke some parts made some mistakes but I finished the build.

Congrats! On the same day they broke news about the core 1 L though. Hope that wasn't bittersweet.
Would you build your second printer? To me that kind of time investment might be justified for a better understanding of how these work and what can go wrong, but after doing it once I would say the extra dough to have it reassembled is completely worth it.
Thank you!
I bought the printer after the core one L news. The core one L is way more expensive (it's almost double the price) so I went with the core one.
Haha. No.
I wanted to build the printer because like you said it helps you understand how printers work and this was my first printer so I thought it was a good idea. It also helps if you ever need to service the thing since you get a good idea of where everything is and what each part does. I also thought it might be fun because some people likened the experience go building a PC and I enjoy building PCs.
Unfortunately I have to say building this 3D printer was nothing like building a PC. It was way more challenging in my opinion. I was also very nervous the entire time because you don't get to find out if the thing actually works until the very end. My heart sunk when I first turned the thing on and the Z axis was just completely not working. Thankfully the issue was resolved after talking with support. Definitely have to agree that Prusa support is amazing.
Also, I found assembly to take way too long. It's my first printer so that might have been why it took 12 hours. I heard it took some people only 7 or 8 hours. I think I would draw the line at 5 to 6 hours for 3D printer assembly if I were to assembly another one unless the printer allowed you to test during assembly.
It is the curse of Prusa. It doesn't matter what you buy, the "next great thing" will always be released while you're building the old model, guaranteed. The good news is they almost always have upgrade kids. And the truth is, you actually probably don't really need it.
I actually wasn't bothered at all by the release. The price tag of the L is insane. And the Core One is already pretty insane especially for me as a hobbiest. I spent a long time trying to justify the price.
Ahh, the Prussian Curse!
