It may seem super silly or I'm just somehow dumb, but the "run a hose to your balcony" is the difficult part for me. That means having a door open for 10+ hours at a time, which is a climate control challenge for the room. That's why I figured: Why not put the entire enclosure on the balcony, and then heat-humidity control the inside of it? Sure, more complex system and higher power draw, ... but maybe there's whole…

6" wide piece of cardboard that is floor to ceiling of the balcony door. Put it on the side where the door locks. Cut a hole near the bottom of it and stick the flexible tubing through it. Now you can shut the door and hold the cardboard in, while still maintaining the climate control. You can use something thicker than cardboard like the plastic version of cardboard... google: 'Corrugated Plastic Polycarbonate Acryl…

Some balcony doors aren't sliding but instead swing open, so that makes it more difficult as well.

Having messed with 3D printers since before the iPhone came out, I can confidently say My MK3 is the best printer I've owned in terms of value. I can only imagine that they've improved upon this story with the MK4.

I'm relatively new compared with you, but I've also found my MK3S+ to be super solid and output high quality stuff. I previously had a da Vinci Pro, and my best metaphor is that using the MK3S+ is like writing with a new pencil vs. one full of broken lead.

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 know it is anecdotal, but I have been tinkering with 3d printers for over a decade, and Bambu Lab to everything else is like ChatGPT to Stack Overflow. It is just unbelievably reliable.

> The idea that someone who is happy with a different product is somehow wrong or losing. Actually, it wasn’t really that I thought they were wrong/losing, it was more a response to the virtue signaling on GP. Nobody cares they canceled their order because they read some words from random people on the internet. Honestly, nobody should care I’m happy with my purchase either! :)

Yeah, I'm not trying to peg the attitude on you either. I've just seen that in 3d printing (and many other topics) threads, and you reminded me.

Yeah, mea culpa for falling into the trap of ambiguity there. Agree it’s too prevalent and should’ve done better to distance myself from that toxicity.

Personally, I think buying any Chinese product when an alternative exists has become unconscionable. China's current support of Russia is an obvious issue, as well as their threats towards Taiwan and their destruction of democracy in Hong Kong. Problems with IP infringement abound, and in this case it's particularly disappointing as Prusa is committed to open source. I hope Prusa continue to innovate, but I also hope…

I'm totally unfamiliar with the company that makes the Bambu, but do they have ties to the CCP or is there evidence that buying this printer would further the Chinese government's efforts?

Bambu just proves the point. Do you think they are going to make more integrated and closed systems or start opening up? Someone has to take the hit with development. And that costs money. > but the value of their devices to date just does not equal the price Has the value in terms of price to features ever really been competitive? I got the MK3 soon after it was released and even then you could get an i3 clone for m…

In the last year, I've bought two separate sub-$250 3D printers that I just threw on a table after connecting four screws and a couple cables and they were dead-on out of the box. Prusa's hat has been "it just works!". That's been the conceptual moat. That is the part that isn't distinctive anymore.

Most cheap tools work at least once right out of the box.

They added a button to convert your XL preorder to an MK4 order with priority . So they're alienating people plonking down $1,000 for a printer by letting people from an unrelated queue jump in front of them... And then shaking the faith of people who already waited this long for the XL. It starts to scream "we won't even be able to make enough XLs and would much rather you just forget about that". - Edit: Wow and ac…

Perhaps they set aside some percentage of XL preorders worth of MK4s that are ready to ship. As long as they overestimate that number vs reality, they can ship to the MK4 first order and XL conversions first, then start shipping to those that purchased with Lead Time stated. And if they over estimate the conversions, (almost) nobody with a Lead Time is going to complain about getting it early.

Based on their wording I had already assumed that wasn't the case, but here's some some confirmation: https://www.reddit.com/r/prusa3d/comments/1266bzi/mk4_delive...

> So if you ordered the 4 know that those swapping their XL orders have bumped all those that ordered quickly. I was scheduled for delivery next week and now its June.

Placate people you already disappointed for a year by disappointing a new cohort of users. Some companies just do not know how to let themselves win.

Would someone explain what is notable about this? I'm not familiar enough with the 3D printer space to know what new features and capabilities are developing.

Most of the listed features are incremental updates over the previous model; the MK3. However, as someone who's been using 3D printers for about 3 years, I'd say the biggest improvement here is the automatic first layer calibration. Until recently (most notably until the Bamboo Labs Carbon X1) you had to spend time setting up your printer to get a good first layer. This would involve changing the distance between the…

That's a great explanation. Thank you!

I've done a great deal of printing, both with the lidar enabled and disabled. For PLA it doesn't make a big difference. But when you're printing polycarbonate or PETG, the quality difference is dramatic. Perhaps you have a defective unit?

I also assumed the lidar is a complete placebo having owned the P1P and seeing how well it prints with PLA plus looking at available lidar sensors and their accuracy but maybe it does work? Would love to get a teardown on what components it uses but couldn't find anything online some months ago.

You don't need it if you print slowly, and you don't need it for reliable old PLA. If I squint, I think I can see a difference, but it's marginal.

Thing is, the X1C isn't really for printing PLA. If you only want to do that, you'd get a V400 or a Voron. When I print PC Blend, though, it's... the difference is glaring. This isn't something that needs a lot of testing; with the lidar off, the corners look like semicircles.

Also monotonic top/bottom layers don't fill the full surface, because they have corners on both ends. About like you'd expect, and the difference isn't visible from the outside; external perimeters are always printed slowly anyway.

Disclaimer: I have had my personal details stolen from by China before with the OPM hack (US security clearances). I'm pretty sure they stole my fingerprints. I guess that may make me biased...

It's not that they have ties to the CCP. It's the fact the CCP can order Bambu to give up their data without a warrant showing criminal activity.

By bambu labs own website, they have locations in China, which means those sites are governed by Chinese law.
