The XL is done forever, man. Game over. It's all gone to hell.  

RE: The XL is done forever, man. Game over. It's all gone to hell.

I personally didn't like prusa's xl enclosure solution and I'd love for them to come out with a kit to convert the xl to look something more like the core one L.

I've been working on something like this for about a year now. It's not exactly the same as the original case, but more of an ‘upcycling’ project. I hope to be able to show you some pictures soon.

RE:

short note. I have had Creality and Bambu  and Prusa printers. All at one stage went wrong. Only difference is I got help fromprusa the same day. Even a Sunday. So even though my XL5 tool is a bit old now. I am sticking with it. Does all I need to do and the customer service is the best of all thanks prusa 

RE: The XL is done forever, man. Game over. It's all gone to hell.

I’m glad Prusa created INDX. It has the potential to move the slicer toward a more mature multi-tool workflow.

I mainly use OrcaSlicer, because it handles supports better. I’ve owned an XL5 for about a year, and I also use a Bambu X1C. Before that I had an MK2 (2016), which replaced my Repman (2009).

With INDX, I hope Prusa will now focus more on slicer features that are essential for real multi-tool engineering workflows, not just speed or convenience.

Things I would really like to see in PrusaSlicer:

- Proper support for multiple nozzle sizes in one print (no longer experimental or blocked by warnings)

- A better wipe-tower / purge strategy for multi-material printing

- Automatic nozzle selection in the slicer (rule-based, not “magic”)

- Per-tool temperature management, e.g. different first-layer temperatures depending on what filament is underneath

- Dynamic nozzle temperature changes, for example to emphasize wood grain in wood filament

- Improved thin-wall handling, configurable per filament

- The ability to reliably print very fine functional features (I print antennas)

- Different speeds per tool

- Different extrusion widths per tool

- A more predictable wall generator (currently I still need many test prints to get deterministic results)

I could list many more multi-tool features, but the main point is this:

Until recently there were relatively few XL5 users compared to the smaller Prusa printers, so software development understandably moved slowly. For me, the main limitation of the XL is software, not hardware.

The XL is a bit like a bulldozer: very capable, very stable, but you shouldn’t expect Ferrari behavior. The out-of-the-box speed profiles are too aggressive for precision work.

INDX is brand new and will need time to mature. As soon as Prusa’s multi-tool solution can reliably print finer features than my X1C, I will seriously consider getting one. It would not replace my XL — I still need the build volume. In fact, my XL is currently printing an instrument case that only just fits on the bed.

So: well done, Prusa — keep innovating. And while you’re at it, please also look for a more robust solution to the fatal error caused by noise on the tool-head connector.

RE: The XL is done forever, man. Game over. It's all gone to hell.

Prusa, you need to address the neglect of the XL early adopters. My machine has 520 hours after 2.5 years—my Snapmaker U1 has doubled that in just 73 days. Why? Because the U1 works and the XL doesn't.

You have my serial number. You know exactly what hardware revisions have been made since my unit shipped. Instead of focusing on the next upgrade cycle for the Core One, I’m asking for a serial-number-specific document that lays out exactly what I need to fix to make this printer functional.

We paid a premium for a "workhorse" that has turned out to be a hobbyist's headache. I won't be purchasing a Core One L or any further hardware until I see a real commitment to the people who invested in the XL.

RE: The XL is done forever, man. Game over. It's all gone to hell.

Mine runs like a metronome , although I use it for printing 20-30 small and short things, but my biggest issue is bed adhesion, which this does great.  My CoreOneL seems to have a split personality.

I think the XL is like the B52 bomber, it is just going to weather on, hopefully with the same kind of upgrades. It has unique properties and abilities.  I’m hoping for a renaissance after the INDX is launched. 

RE: The XL is done forever, man. Game over. It's all gone to hell.

My PrusaXL also works and works and works without any major problems and the minor problems are mainly user errors.

RE: The XL is done forever, man. Game over. It's all gone to hell.

Greetings all;

I wanted to take a moment to chime in. For those who don't remember me. I was the forum admin a few years ago and also I was involved in the XL beta test. I will be returning to an admin position in the forum along with a few other things, but I wanted to address this thread a little bit.

As much as it does bother me to read these comments, I do understand and I can put myself in your shoes and relate. I also have experience and knowledge working over here and I can honestly tell you that the XL is not a dead project, discontinued, or anything like that. I can also tell you that I took the link to this entire thread and shared it internally, no TL;DR, no notes, no short version, no report, just the full thread so other departments can see your concerns. 

With moving back into an admin role, there are things that I plan on working on with the forums and I will be taking direct feedback from here to various departments over time along with some other things. 

I get the frustration and as a few people mentioned, most people jump on a forum when things are bad and I hope in the long term I can try and set up some new things that will slowly change that mindset and make this a interesting place for the community. 

RE: The XL is done forever, man. Game over. It's all gone to hell.

I'm glad to hear that, to breathe new life into the dusty XL and to get the Prusians, who are too fixated on the C1 and C1L, back to work on their flagship model!

RE: The XL is done forever, man. Game over. It's all gone to hell.

I'm glad to hear that Shane has shared this with Prusa. Looking forward to some renewed attention on the XL. If they could turn my MK4 into a C1, surely they can do some magic with the XL.

RE:

My first and only printer has been the XL and it has been one hell of a ride. Some of that is my fault for jumping in both feet with what was essentially the tinkerer's printer, but looking back, it really wasn't marketed as that at the time of purchase. Almost every printer then looked like some collection of frames and NEMA motors, the XL was presented as the most advanced and easiest to use printer. Auto leveling, perfect, modular-heating, multi-nozzle, massive build volume, she had it all when I bought her. I truly loved her then and now. But it hasn't been a smooth ride. 

Out of the gate I ran into various Puppy Board errors. Sometimes it would lose power in the middle of a build without reason. Other times it would just refuse to boot up. There were plenty of hours of happy printing, but when an error popped up, it was often a long and laborious investigation mixed with trial and error. Prusa support is always incredibly helpful, attentive, and thorough. Juan D. is a legend and remembered me every time I hopped into a live chat. Still, I've had to replace every board on my machine and probably 1/3 of the wiring over the life of owning it just tracking down issues. The latest of which being the dreaded Puppy Error modular heat bed #17514. It's been a great learning experience and it truly is a beast of a machine when it's up. But when it's down, it can be a real kick in the ribs, often leading to it sitting for months until you can muster up the motivation to take it all apart again.

I've upgraded her to 5 tool heads, full enclosure, hardened nozzles, and a ton of improvement parts I've printed and installed to resolve the various shortcomings of the design. I've definitely sunk over $4k into her over the years in upgrades and replacements. So for owners like me that were in over their head to begin with, thinking they were getting the highest-end, plug and play model, to see the Core One L already fully enclosed and assembled for a quarter of the price, then to hear tale of it getting INDX 8 support soon, that kick doubles and moves from the ribs to quite a bit further south... 

I see the silicone upgrade planned for the XL, that is cool and exciting I guess, but... What is the actual heat resistance of this silicone since Filament2's "website" is a single page with almost no information on it? What will the price of this two part material be? Is essentially a single mixing toolhead gearbox with a knife really worth the price of a Core One+ kit..? Will I really ever use this additional $1000 upgrade enough to justify more sunk cost into the XL? Then there is pick and place aiming for the end of this year. Meanwhile, Core One users already have a 400 degree nozzle, 60 degree chamber, and an 8 filament changing system all for less than half of the cost required to fully upgrade the XL. Wew lad...

I don't want to say I've got buyer's remorse because I enjoy my XL but I am green with envy looking at the new flagship. The February 17th article really more highlights how in the dust the old girl has been left. I mean even the printer is $200 cheaper due to production improvements but the nozzle upgrades have never been on sale lol. 

I wish XL users had something else to look forward to or at the very least a trade-in program. 🤣 

RE: The XL is done forever, man. Game over. It's all gone to hell.

My prusa XL has been a reliable workhorse since day one and earned itself back many times long before the Core one was announced. I also think you should not compare a toolchanger to the INDX, its a totally different beast. However i am disappointed in the lack of different tools. There is now a head for silicon but i was expected way more tool options around this time. I hope the rumors are right and we see more toolhead options in the near feature.

RE: The XL is done forever, man. Game over. It's all gone to hell.

I appreciate everyone jumping in here to discuss this. While it’s good to see a Prusa representative finally engaging, I have to be honest: reading the new "XL in 2026" blog post felt like a bit of a slap in the face. It tells me Prusa is very excited about the future of the XL, but it says almost nothing about the people who funded that future and are still stuck with machines that don't work.

To those saying your XL "works fine," I genuinely mean this: check if you’re actually using the features you paid for. If you’re mostly doing small, single-tool prints, you aren't really using an XL—you’re using an incredibly expensive, oversized MK4. The XL was sold to us as a multi-material workhorse for large-scale projects, and that is exactly where the early models fall apart.

It’s been a long road for us "pioneers." We gave Prusa our money in 2021 and waited 18 to 24 months for delivery, only to receive what has turned out to be an alpha-stage product. Calling this a "4-year-old printer" is a myth; for the consumer, the clock didn't start until the box arrived, and for many of us, it arrived with inherent flaws.

The most frustrating part is seeing how the "solutions" are being handed out. When a high-profile creator like Michael Laws from Teaching Tech couldn't get his early XL to work reliably, Prusa didn't tell him to spend three days performing a complex CoreXY plastic part replacement. They shipped him a brand-new printer. They effectively admitted the early hardware was problematic by replacing it for someone with a platform, but for the rest of us, the "fix" is a link to a factory-level teardown guide. Why should we be expected to do Prusa’s assembly and QA work on our own time?

The math just doesn't lie. I’ve had my XL for 2.5 years and only have 520 hours on it because it's constantly down. I’ve had a Snapmaker U1 for 73 days and already have 1,000 hours on it. One is a tool I can rely on; the other is a project that never ends.

I’m a long-time Prusa fan—I’ve already moved my MK4S to a Core One because they made that upgrade path easy and logical. I love the concept of the IDEX and the Core One L, but I won’t be purchasing anything else in the XL ecosystem until I see that Prusa is actually here for the users who supported them from day one. We don’t need a blog post about 2026; we need a functional solution for the machines we bought in 2023.

It was still working OK yesterday with a full-bed print (the wipe tower had to be minimised and moved) using two colours of PETG and TPU for hinges ... and two of the original 0.6 nozzles plus a replacement.

Cheerio,

RE: The XL is done forever, man. Game over. It's all gone to hell.

There are always people that are ok with a product and people that are not. In my case it works ok for simple prints, does a good job for multimaterial (except soft tpu) and is not so good with abs asa etc. I bought the enclosure to stop warping and i cant print due to module overheating errors. I changed the heatbed controller , moved around tiles but the problem remains. The problem goes away if i live the enclosure door open. Which is kind of funny since the enclosure is already filled with air gaps. The issue here is not if it just prints. Is if this is how  4k printer is supposed to get treated by the company that promoted it as a flagship a few years back. And even if it works, there is no actual improvement presented by the company even if there is reason and room for it. Printing tpe83a and seeing it warped around the nextruder gears is not something that shouts 5k well spend.

 I mean yeah a hackerboard for 1.5k core one is obviously more importand than cooling improvents or tpu loading fixes on a 4k machine. I mean lets improve the nextruder part cooling on the mk4s extruder but heck who cares about the XL. They can print mods from printables.  Prusa advertised easily implemented multi size nozzle print during a project. Heck its not that it cannot be done.. you just have to play around a bit in your slicer. Aa lets give them an enclosure... Lets give them a box with no actual heat sensors and put a hefty price on it because.... its a Prusa box. We will peoperly enclose our core line because we are running behind bambu labs. Etc etc etc

Thats the issue imho. As a printer it works now. As an advertised promoted and costed flagship it still falls short and thats not due to a bad design but my opinion to lack of interest from the company because price wise other companies caught up, while this was marinaring for two years after announcement and until its first release. 

And finally they are so proud because another company presented a silicon head that cost more than 4th snapmaker u1. 

I srill like it and use it .. what i actually dont care any more is the Prusa name. It doesnt worth the Premium. BL, snapmaker or even creality hhave nothing less than prusa. Except the price of course.
