My printer today looks nothing like the printer I started with, I’ve switched boards, recompiled my own firmware, the whole bit. I was confident in hacking on it for two reasons:
1) It was open source based
2) Replacement parts are inexpensive
I originally started with a Makerbot 2X which was closed source and $2500 (8+ years ago). Mind you, I didn’t have one at home- we had a couple at work for prototyping.
The slicing software was atrocious, the ability to fix it was hampered by what parts they sold, and the replacement parts were generally very expensive.
My $250 printer was better in every objective measure out of the box than the MakerBot was after years of practice and tuning.
This year my friend’s 2X died and a replacement motherboard was going to be almost as much as the cost of my printer new so he just gave it to me and bought a new printer.
With my newfound confidence from my “cheap” printer, I gutted the 2X and installed an open source motherboard and completely rewired it.
It all started with a printer good enough to be liked by the community and open enough to be modifiable.
The printers after that switched to the new hotends that are not user serviceable. It boggles my mind why any home user or tinkerer would ever sign up for that crap.
BUT...
My brother in law teacher, who teaches various middle school classes and groups use them. I asked why they would waste so much money and he had a response that made it all make sense to me. He doesn’t have time to keep them all running all the time (like we had to do with the old ones) and when one goes down he gets replacement parts from MB at a discount, slaps it in, and they’re up and running again. Apparently the latest ones are fairly reliable and it doesn’t happen all that often either.
So I guess I would sum it up as not for me, but I could see why some would.
