If you buy a Prusa in non-kit form, it's not any harder to unbox or operate, and more reliable, while generally achieving somewhat better results. Without phoning home and while maintaining the software Bambu forked theirs from. A recent review coming to a similar conclusion was Maker Muse' review of bedslingers. It's a channel I respect a lot, because he has over the years relentlessly disclosed emails of companies…

I'd also like to add that my Prusa Mk3s+ is significantly slower than my P1S. Also, without the MMU it still cost more than my P1S with AMS. Choosing a Prusa is making a philosophical choice, because it's certainly not about convenien…

The mk4 and mk3 are vastly different machines. If you want to compare the P1S, do it against a contemporary machine. Of course a machine released several years after the mk3 is faster.

> But look, you want to do 3D printing, 40 hours are just a small initial investment No. None of this crap. I want to 3D print. I don't want to service industrial machinery in my spare time. Why should 3D printing require spending weekends troubleshooting machines just to keep the thing working? I want to print models not play repair technician. Vorons are fantastic printers and a fantastic kit if 3D printing itself…

QIDIs might need a slight bit more tinkering with settings for new filaments but they’re pretty solid and offer more than Bambu does for the money Comparing Bambu to Voron is an absurd comparison

> Comparing Bambu to Voron is an absurd comparison

I politely disagree. I was in the market for a more modern printer, and it boiled down to either a BL or a Voron - in the end I decided against ease of use and in favor of an open ecosystem. I agree in that they are not universally interchangeable, but for some people either can be an option, each with distinctive advantages and disadvantages.

I know it's not exactly a zip bomb, but it's kinda close, and goddamn, that's obnoxious.

Well, they DID remove expected performance by slowing CPU performance, disn't they? People who had bought these iPhones (and not the previous ones) did so also because of the promise of a more powerful CPU, a promise broken by Apple. It is removing a feature (a better CPU) and Apple knew it that's why they did it without informing users.

> because 3d printing is not there yet Ya, it is, and it’s been there for quite a while now thanks to Bambu. The X1 just works. Coming up on a year of frequent use, I can count the number of failed prints on one hand. It’s incredible.

i do not believe you. it is mostly a material issue not a printer issue

Both modern (pre assembled) Prusa and Bambu are very good at this. They guide you through the full setup process, automate first layer reliable, have decent stock profiles.

It's all just much less tinkering then 5 years ago.

I personally think the outrage I've seen on this issue is generally not justified. In general people are just scared of change and on top of that are playing telephone on the details of the change, assuming the worst intentions from Bambu like they're trying to be the next HP. I have seen a lot of misinformation on this topic, and I think that in that sense it's a good idea to read the actual announcement details to…

well, it's they really meant improving security they didn't do great job, as you can see people broke this security in a day

blocking printing from sdcard in Lan mode basically deny any claims that this change was poorly communicated improvement

You're saying this yet anyone can buy a random Bambu and just print. I've owned or used probably every major (and some minor) printer released in the last 8 years and for most people Bambu really will just be "plug and play" (and even if something goes wrong they'll hold hands as much as needed)

as i said to another reply, it is a material issue.

That does not match my experience. The printer I have has had parts break with light use, and a really poorly engineered z-axis homing which results in wildly inconsistent zero heights and a very high print failure rate.

the problem isn't that they've done it.

the problem is that user got no choice. Some might prefer degraded performance, others might prefer to charge their devices more often.

Also seller should have no business touching anything that they've already sold - they do might offer support, but it should be up to user to accept it or not.

It is. I have no interest in messing around with 3D printers and was annoyed by the fact that Bambu lab lied about the 15 minute setup time. It was more like 45 minutes, but after that I never touched the printer again and started printing instead. Also, subtractive manufacturing is much harder than additive manufacturing, because you need to position the machine around an existing piece of stock and sequence your op…

it is not that. i mostly mean that for anything functional that needs to take a load you need at least petg or asa (abs is a bit old now), which require proper storage. also there are so much stuff that are in open prs and issues for years that are not implemented for slicers.

I think the AMS unit for the Bambu is somewhat sealed and has desiccant in it.

"take a load" - I don't know what kind of load, do you mean the fact that PLA is creeping under sustained load?

If that is YOUR usecase that is fine, but that does not mean that set and forget works just fine for others. Btw gun people use PLA plus just fine.

Maybe bamboo printers were too cheap which lead them towards their subscription based model. Everyone complains about enshittification (YouTube ads, subscription models etc..), but then refuse to pay the real price premium goods and services cost. You get what you pay for.

What subscription? They're restricting remote access APIs in new firmware because they pose a security threat.

I don't know the details or if it's true, but someone who was in the firmware beta claimed there was //commented-out code about different subscription tears. Maybe just a test, maybe for print farms .. maybe it was all a lie.
