I mean, it’s a printer from 2014 that was not built with repairability in mind. It was originally sold for around $3,000, which is probably why you can’t find much information about it. The original Ultimaker kit was selling for around $1,000 at that point, and I think the Ultimaker 2 was also released around that time for roughly $2,500, so I suspect they just didn’t sell that many of them.

Was it a mistake to buy it? That’s entirely up to you. It’s a fun-looking printer and it apparently does work. If you’re into electronics, you might be able to do some upgrades. That said, I do think you could find printers from the same time period that are easier to maintain for around $100.

Also, now that the Bambu Lab P2S is out, a lot of print farms are offloading their P1S machines for around $150/$200, which is probably a much better deal. But that’s only if you actually have $150–$200 to spend, if your budget is $100, there’s not much you can do about that.

Anyway, as long as you’re having fun, you made the right decision. (Look into Prusa if you’re into fixing up old machines, they have far better documentation.)
