I paid ~$750 for my 350mm Voron 2.4 kit (and, sure, 40 hours of my time. But look, you want to do 3D printing, 40 hours are just a small initial investment).

> 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…

>Why should 3D printing require spending weekends troubleshooting machines just to keep the thing working? I want to print models not play repair technician.

I’m sympathetic to your POV but the reason you should is that’s the price to keep things open.

Obviously many people don’t care about that. Fair enough. But then you should be prepared to deal with their shenanigans.

Prusa also does things like maintain and develop printables.com and PrusaSlicer (itself forked) which many of these closed printers fork with minimal changes.

People don’t care about this either. So again, get ready to deal with garbage when Prusa goes under.

I think it’s sad since the whole domestic 3D printer thing started as open source.

Open source didn't compete on quality for price. I could pay 2k plus 40 hours of my time for a Voron or buy something that just works. I think Prusa only put out their CoreXY offering after they realized Bambu was eating their lunch. The Apple model works because people want to print rather than tinker.

Well Prusa was open and did compete. But for 3D printers that worked out of the box under $1000, Prusa had no real competition itself. The Mk3 came out in 2017 and I swear Prusa just sat on their laurels. I was a Mk3s+ owner (well, still am) and was pretty disappointed how little improved with the Mk4. Bambu’s competition was Prusa and they clearly strived to improve over what Prusa had accomplished.

I wasn’t really sold on the 4/4S, but I recently upgraded a 3S+ to a 4S and am amazed how much improved. The new touchscreen LCD is a huge improvement over the old two line monochrome LCD. Remote access and wife printing is a nice plus — I don’t even run OctoPi anymore. Automatic bed leveling and no more Live Z tweaking for each sheet has been a major quality of life upgrade and eliminates one of the major pain points in swapping out nozzles. The nozzle is much easier to swap out and is now high flow. Add in Input Shaping and it prints significantly faster.

I hadn’t had any experience with the new platform prior to this upgrade and I skipped over the MK4, but the 4S upgrade is a significant step up over the 3S/3S+. I wouldn’t necessarily recommend the upgrade kit — that took much longer than expected to complete (about two days) and I regret not buying a new printer instead. But, I have a 3S I plan to upgrade to 3.5 just to get the new electronics; that upgrade is far less intensive.

If you haven’t tried out a 4S you might be pleasantly surprised by how much nicer it is than the 3S+.

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

> it is mostly a material issue not a printer issue Tell me you don’t anything about 3d printing without telling me you don’t know anything about 3d printing.

if you think that there are not limitations with current fdm thermoplastics and software, i do not know what to tell you.

because 3d printing is not there yet. the whole process is basically cnc but with z hops and extruding instead of removing material. we do not even have conical slicing yet.

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.

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.

…for now….

But yeah, the enshitification economy has made people justifiably paranoid that if a product starts exhibiting new capabilities or features that would seem to support or enable a move towards subscriptions, it’s a good bet that that is in fact the trajectory of the platform.

But afaik Bambu has neither confirmed nor denied that this is in the works.

I wish Prusa weren't asleep at the wheel, then we would have bought a core one (that is, the hypothetical variant with large build volume and same quality as bambulab).

Instead, we bought a P1S, which is, technically speaking, a fantastic machine.

From their blog post: https://blog.bambulab.com/firmware-update-introducing-new-au... "Critical Operations That Require Authorization The following printer operations will require authorization controls: Binding and unbinding the printer. Initiating remote video access. Performing firmware upgrades. Initiating a print job (via LAN or cloud mode). Controlling motion system, temperature, fans, AMS settings, calibration…

Yep -- I read that, but that doesn't spell out auth back to BBL's servers, just auth. And keep in mind that OrcaSlicer already used Bambu Network Plugin to communicate with their printers. (It prompted you to download this on install of OrcaSlicer if you picked one of their printers.) The move to Connect means that OrcaSlicer needs to send the print data to Connect via a protocol handler instead of to the plugin. Con…

"Operation Guide for Bambu Connect

Start by logging in to the Bambu Lab account or click Discover to find LAN mode printers."

At the very least - it looks like you'd need to log-in to the cloud account to print on the LAN, which really begs the question.... why?

wife printing sounds nice!

As opposed to the device unexpectedly shutting down due to a degraded battery not being able to push enough energy to support the CPU? They didn't remove expected performance, they prevented crashes which are by definition 0 performance. All Li-ion batteries degrade over time. That's not removing a feature...

This whole thing was totally overblown.
