Has anyone figured out remote slicing? I’d love to just click print on a thingiverse page and have my printer start going.

Options have existed for awhile, but unless you have the specific slicing profile in mind (which is NOT the same for every file; some might need supports... some you might not care about quality, etc), it's not going to be one-size-fits-all.

As others have mentioned, the closet is using something like PrusaSlicer and using 'Upload and start print'. You do the slicing manually, then you just press a button and it uploads the gcode and starts printing.

These are nice and I have MK3 as well. However, I am doing most of my prints on HP MJF these days. It’s so much better and the cost is very reasonable. FDMs are good toys that require love. A lot of it (which can be good and bad).

These look like very solid improvements over the MK3S+ (I personally have two MK3S+, and use them a lot), and I love their commitment to open hardware and for making upgrade kits available, but it's a bit disappointing to see still how far Prusa is behind truly next-gen printers like the Bambu Lab X1-Carbon.

I have a Mk3S and a Bambu X1C. The Bambu is much, much better.

The Mk4 covers most of the distance, but at a price point matching the X1C, and it's only most. Speeding it up is nice, but... pressure advance depends on detailed characteristics of the filament, such as viscosity, which varies from brand to brand and color to color.

The X1 has a lidar, which from experience actually does work as advertised. The Mk4 has... what? Prusament, maybe? I would not be surprised to find you can only get the advertised speed if you use Prusa's precalibrated filament.

Or you can print the calibration lines and do it manually. That does work; it's a ten second eyeballing procedure, simple enough for the X1 to do full auto. But you're really supposed to do that for every startup -- characteristics change as the reel ages, which doesn't even happen evenly across the entire reel -- and nobody does that.

I have had mine (w/ four total AMS units) for two months now and have over 500hrs of printing so far w/ minimal failed prints. I often print in sport and/or ludicrous too. I own eight other 3D printers of various major brands (including Prusa) and it’s by far and away the best I’ve ever owned. Easily comparable to printers 2-3x more expensive imho.

> It is insanely loud, and it seems unreliable and buggy.

Even with the door open to the room mine is in, I never hear it. Sure, if you’re within 5ft of it, it is a bit loud, but not terribly so, especially if you reduce fan speeds (they have conservative defaults). If you are someone who wants to sleep next to your printer farm, maybe not a good fit, but for any normal person the noise isn’t a concern imho.

> I just canceled my X1-Carbon order.

Your loss! I’m doing the reverse, thinking about buying another one.

I have a Prusa MK2 clone that I recently revived with Klipper firmware, a cheapo Kingroon MK3S Pro that I bought to tweak a bit, and have been looking at getting a Bambu Labs or building a Voron - and either of those seems like a better investment than the MK4 if you can build and tweak the printer yourself. But the key thing is that the Bambu (and other upcoming Core XY printers) are aimed at the non-modding market…

How is the Bambu a better deal? All I'm seeing is a $1500 printer. Is there some other model?

I own two MK3s+'s. They are solid machines if you are looking to print PLA and some PETG. The stock extruder is a PITA. The MK4's redesigned nozzle/heat break & 10:1 extruder are basically a Bondtech LGX + Revo & should make for a great improvement. The MMU3 seems like a marginal improvement, you still have purge towers & large buffer boxes. Hopefully the reliability out of the box has improved. I wonder if it's too…

It seems like an odd place in Prusa's own product line-up.

I have a Prusa MINI+, which for $450 gets you a great printer. The print volume on the MK3 and now MK4 is just not that much better - 180x180x180 for the MINI, 250x210x220 for the MK4.

If I wanted to upgrade and wanted to stick with Prusa, MK3/MK4 wouldn't come into the picture, I'd go straight to the Prusa XL.

I'm not sure about too little, too late. All the different brands are the flavor of the month ARM SBCs vs raspberry pi -- Prusa may lag in features, but at least I've heard of them, they have a community, and they're not going to disappear tomorrow like something off ali baba.

I've been always a huge fan of Prusa and always wanted one (just haven't for various reasons, not so much financial related). But this feels too little too late. Bambulabs is absolutely eating the market and I would be sweating if I were Prusa Research. It sucks since Bambulabs is using their slicer and a lot of Prusa's technology as a foundation. But most of the people I know have decided to skip waiting for the XL or MK4 and jumped for the X1C instead. No joke, the past purchases in the past 4 months or so from my circle of friends and peers have all been the P1P or X1C.

Edit: Also, its 799 for the kit you can't buy now compared to 699 for the P1P that you can buy today and literally prints out of the box.
