there isn’t a “best” really. Depends on your wants/needs.
for true Openness, I don’t think anything beats a Voron.
Prusa is great (good track record, good support, Hardware is not open anymore though, can work out of the box), but expensive.
plenty of others get you something largely decent for low prices (qidi, creality for example) but long term support seems likely to lack, and there are always reports of some issues for some and great results for others.
The Security argument doesn’t hold water when you’re pushed toward the cloud use for transmitting data over your own network cable would suffice.
Define APIs and API keys (local and cloud).
Instant safe communication, local and/or cloud.
I don’t see it this way, for multiple reasons.
If my understanding is correct, they are (imho) misleading if not lying in this post, when they say:
these claims are entirely false:
Bambu Lab will remotely disable your printer (“brick” it).
Firmware updates will block your printer’s ability to print
But they integrate a certificate which has a validity date.
Once that update is on, you’re kind of locked to their releases. Yes they now, after the backlash have realized that they are putting up the walls a bit too quick. But I do not see anything in there that says “we were wrong to do it this way” - which they are.
There is little reason to - by default - put the cloud inbetween your PC and your Printer, which may sit 2m or less apart. That never makes anything more secure.
Neat.
Curious to see if the reliability of ejection (and adhesion) really will end up being worth the added mechanical complexity.
remember, most prints take hours, and taking them off plates takes… a few seconds to minutes.
that is more editing and good lighting.
there are always layer lines.
Depending on you I would recommend
Voron (DIY, will take about a week to build and a week to tune),
Prusa (depends on your preference, assemble yourself or built, depending on required time a mk4s with mmu3, or the core one which will take several months to get to you, and the mmu3 later when it will become compatible)
Qidi (cheap, chinese, will likely work decent after some tuning)
