Thank you for actually showing how the tool change mechanism works unlike basically every other video about this printer.

[@maltoNitho]

I came for the XL but I’m commenting about the sponsor. TLDR; do NOT buy from FlexiSpot. I ordered my desk 20-Feb and it’s now 21-May. They CANNOT tell me when my desk will ship and they refuse to make any concessions. I’m debating canceling my nearly thousand dollar order as result. I’ll be telling this story in every YT comment I can find.

[@kyle8575]

That sucks. Was this from their site?

[@radish6691]

Cancel your order. If you don’t then you’re just validating their bad customer service. Then take your money to IKEA because their standing desks are very solid and work great. I have a Bekant but they’re closing out that line…good news is they’re discounted now.

[@aj_mcnamara]

I got an UPLIFT desk 2 years ago. It shipped fast and has worked great.

[@JH-zo5gk]

Cancle it. Get a eureka. Their customer support rocks. They sent me new parts for my desk I ordered like 6 years ago and they didn't even carry any more. Parts I lost when I moved. They searched all over and couldn't find me my part, so they made it for me and sent it to me for FREE. Way, way, way after any support could have been expected for a user caused error.

[@BaioWithMayo]

Ive had the XL since Feb of this year (5 head) and my hands down favorite part is using PLA/PETG/Polysupport (a dedicated breakaway material) for the support interface. This has made downloading random non-3d printed designed models and throwing them into slicer with basic settings a breeze. On the model its perfect overhangs and has broken me to think "yeah a massive curved overhang over nothing will print fine" its been THE game changer, and makes all parts look professionally done. Only thing I need from Prusa is allowing us to customize wipe towers, so I can have 4 colors of the same material wiping into infill and only have a wipe tower for the support and my main material since thats all thats needed. If you havent tried using it with a dedicated multimaterial support, highly recommended. Its the only printer that can do it and I will never go back to a printer without at least 2 print heads... my poor wallet

[@javitoto]

Hi, do you use poly support for both PLA and PETG prints? Just for the interface layer or for the whole support structure? Many thanks!

[@BaioWithMayo]

@@javitoto Polysupport just for PLA. PETG I dont believe works and I havent tested it. I have a spool of PETG that I tried using PLA to support and it kinda works, but not great. Could narrow it down with settings. I use it just for the interface layer since Polysupport is $40/750g which is EXPENSIVE, and it works great. Takes some time to get your settings dialed in like anything does though

[@AckzaTV]

isnt special pla support expensive if youre throwing it in teh slicer? ion my a1+ ams lite i have to wastea lot of filament for changes and i wish bambu would just let us go without wasting filament just cut and go and deal with the color or put it on inside the walls infill sparse filling flsyhing etc

[@BaioWithMayo]

@AckzaTV on Bambu in particular the changes are expensive because of the "poops". The prusa MMU3 apparently is a little better, but the XL only uses a small purge tower to equalize pressures. Plus I only use it on interface layers. 0% gap, perfect curved overhang, and easy to remove. On my bread and butter 160g print, 5g is all the dedicated support I use. That's (if perfectly efficient) 150 prints I can get off one 40$ support spool

[@andrux555]

I was considering adding XL 5 toolhead machines to my farm, but this and similar comments have set me to delay this decision and look for alternatives. Any updates on this @BaioWithMayo how it was solved?

[@wiseovertime]

I finally received my August 22, 2024 full factory assembled Prusa XL 5 Tool head printer yesterday. I carefully took my time to properly follow all instructions to assemble and set up my printer to make sure the assembly was executed perfectly. All tests and All calibrations passed and were successfully completed the very 1st attempt. All showed green check marks and heated properly for all 5 heads. All filaments we’re also loaded 1st try to all 5 heads and extruded PLA in all five heads successfully the first attempt. My first test print was also perfect and flawless. I could not have been happier, and I was glad I took the extra time to make sure it was perfect. My second attempt was to print the PLA, PLA, Flex wrist CT scan model that comes on the flash drive with the printer, but my # 2 head suddenly gave an error message on the screen and the printer shut off and rebooted. The same error message appeared after booting that the thermistor or heat resistor wire has a problem and may be damaged? How, This was just a few minutes after all 5 heads had just heated and passed calibration tests and extruded PLA seamlessly. How is this possible? Nothing touched the printer. I stayed up trying to troubleshoot last night for two hours and spent another hour and a half this morning and an hour just now with support agents attempting to figure out how this went from functioning perfect and passing test to failing without the printer ever being touched, to an error? I spoke with 2 Prusa customer support agents who are unable to understand how to help me and make this right. This is very frustrating after 5 hours of careful assembly, I've lost 4-5 more hours trouble shooting the defective #2 Nextruder after it had just heated up and passed calibration. I asked PRUSA for help and support and tried to explain as friendly as possible that I can't waste any more time on this. I sent pictures and asked to please help me and make this right so I don't lose any more of my time on my brand new $5000 printer. Prusa's solution WAS NOT to overnight me 1 fully assembled Nextruder Replacement with a little store credit or to include a couple extra boxes of filament for the troubles I've had and loss of time on a brand new factory assembled unit, but instead they asked me to carry the burden and do all the work to spend another 2-3 hours 60 steps, disassembling the defective Nextruder, along with another perfectly working Nextruder and swap parts and reassemble to narrow down which part component is defective. And if that does not work, they want me to move on the dissembling both Nextruders again and swapping the next parts to check which adds another 2-3 hours. Keep in mind, I paid $500 extra for FULL factory assembled unit so I did not have to deal with issues or worry about each individual part or waste time making it look as clean as they can from the factory. I don't want to have the burden of not routing all wires and tucking lines back as perfect as they did because I am not as good as they are. Plus I'd have to recalibrate everything again afterwards. I'm a loyal Prusa customer for over 5 years, buy their Prusament filamnet regularly and have convinced my friends and others to purchase Prusa. Is their support satisfactory ? I feel this is not right and unacceptable. Am I off here to expect Prusa to replace the defective Nextruder with a new fully assembled unit like I originally paid for? It's business. I have to support my customers this way in my business, or I'll lose customers to my competitors who also offer this type of support. I'll remove this review once PRUSA steps up to the plate and takes ownership to make this right. Does this seem fair to deal with on a brand-new factory assembled unit or should the guys at PRUSA do the right thing and ship my replacement?

[@Excelcior58]

This is spam. This guy has posted this on every video about the XL.

[@wiseovertime]

@ not spam at all.. I was not getting any assistance or support until these posts grabbed the attention of management.. they shipped the replacement nextruder finally which solved one problem but the unit still can’t even successfully print the models pre sliced and pre saved that come programmed with the unit. Constant filament jams with brand new PLA prusament filament on all 5 heads.

[@PutTheKettleOnGromit]

I print on my Prusa XL 5TH TPU with PLA supports (grid). I use the fully Soluble setting with a 0.1mm offset. I can make proper huge gaskets with complex geometries. So many possibilities.

[@sftzclem]

Great point. This is one of the most overlooked features of having a dual extruder system. It makes for easy to remove and beautiful supports. I do the same thing using PLA/PETG, but I also modify the supports tho only use different materials on the adjoining layers. This saves tool head changes and time.

[@connord816]

I also did the same thing but for a Nerf Nuke model (Think Geek 2014 april fools day prank product) I did the standard soluble setting which I think has 0 offset. Came out fantastic after I figured out the best way to remove the PLA was to dunk the whole print in boiling hot water (not actively boiling)

[@BrainDeath89]

Is Tpu Ethanol and gas resistent? I am using paht cf for intank stuff

[@dark_matter8420]

I just don't understand them insisting the filament needs to be bone dry, but the spool holders they designed are just outside of the frame exposed to air. Meaning they will inevitably absorb some moisture. Or do they expect you to take off all filament rolls after every print and store them separately?

[@TorianTammas]

Yes this is exactly a weird concept. five printing heads need an enclosed dry space to store the filament on the machine.

[@0calvin]

One of the benefits I like about the multi tool head setup on my XL is keeping one tool with a hardened nozzle and one with a .6 or .8 nozzle for the larger, less detailed prints.

[@BeefIngot]

I used to think that, but with faster printers, Id rather just another filament and to print faster.

[@aronseptianto8142]

@@BeefIngot yeah, i don't think for most modern consumer grade printer, nozzle size matter that much anymore. The printer can move fast enough to saturate the volumetric speed cap of most hotend. So you're not gaining any speed by using bigger nozzle, you're just allowing your kinematics to slow down a bit (that is unless you upgraded your hotend with a volcano or smth

[@damianparadis524]

I keep my 3rd nozzle with a 0.25mm nozzle. I've actually had it do perimeter extrusion with the 0.25mm, supports with something else (cheap but dry) for the supports) at 0.6mm, and infill with another 0.6mm. After tweaking, ie stealing 0.25mm settings from one profile for one nozzle and applying it to the 0.60mm profile for a new profile, it worked great. The next goal is to 'paint' the tops of shapes, text, and high detail areas for the 0.25mm and then a 0.4mm for the rest of the exterior.

[@krollmond7544]

You can do different nozzles?

[@AcECraftWorkshop]

You forgot the most important part why XL is so good. Multi material support (PLA PETG) is KING! Its the reason why I waited for the printer so long, and now I have huge freedom is during 3D designing. I find myself more and more switching to a design strategy where I don't care about overhangs and bridges anymore. More and more prints are designed for my XL with Multi-support then to my MK3's. It surprises me how few people I see talking about why Multi Material is such a big deal, maybe I should make a video about it to get it started? X3

[@BennyTygohome]

I think a single nozzle printer with a multi material ability (AMS, MMU3) can achieve the same. For example, the main model is PETG ...build your supports also in PETG. Then when it gets to the support interface layers where support contacts the model that's when it switches filaments for the support interface layer from PETG to PLA. The advantage of XL tool changer is when it brings in the 2nd tool for the interface layers, it probably goes faster (AMS needs to flush filaments)? But it only needs to do that tedious task at the interface layers. If your model had interface layers occurring at many various different layers of the model then XL is clear winner.

[@chrissniederle3960]

@@BennyTygohome That's a bit short-sighted: the XL also uses significantly less material than a system that has to be flushed! Furthermore, some materials have interactions, which is why mixing them is not advisable. As far as I know, neither AMS nor MMU are really suitable for materials such as TPU! The domain is inevitably the color change. Material combinations are less recommendable...! Another problem is if you want to combine different nozzles! For example, I sometimes have orders for personalized key rings that also function as shopping cart tokens. I can print these on the MMU. It works well and was standard before the XL. I had to choose the nozzle as large as possible because of the printing time, but as small as necessary because of the font/graphics. I'm already looking forward to the next job when I can test this on my XL for the first time...! Lettering/graphics and a small "bubble" embedded as separate objects with 0.25 nozzle and "bubble" and base carrier same material. This allows me to print the base support with a 06 nozzle and the "bubble" with text/graphics with a 025 nozzle. It will probably be difficult to print finer and more detailed and at the same time faster and with less material - especially for MMU or AMS, I think... 😉

[@Todestelzer]

I looked into the XL but I bought a Snapmaker J1 for 1/3 of the price in the end. Only 2 tool heads but that's enough for me. And it has a enclosure as well.

[@drstefankrank]

@@BennyTygohome If you have a single extruder, you need to purge a lot when going from PLA back to PETG. I noticed that if you only flush enough for a colour change, the nozzle seems to be contaminated with PLA still and the next PETG layers don't stick. Still, if you need clean supports, the waste is manageable.

[@BeefIngot]

@@chrissniederle3960 I think a lot of what you say makes sense but then ypu think you have 3000 dollars to spend on that waste fioament and suddenly you realize maybe that waste isnt so bad. TPU and other weird materials is where multi tool head shines. Where the MMU systems cant seem to do it.

[@Foxhood]

I really appreciate that Prusa has kept things simple and old-fashioned when it came to firmware updates and configuration. Just put it on the stick and it will do the rest. No data harvesting apps required. Even the belt-tuning is done via a Website tool, and yeah their documentation is great. It has made building the MK4 for me a good experience that just works well on the first try. Its nice to read the XL is pretty much the same experience. Though such a size is a bit beyond my skill-level in regards of mechanical engineering to become interesting just yet.

[@BeefIngot]

You dont need to data harvest to be much more convenient than that.

[@Mike01Hu]

You mentioned step artifacts and pasted the question "is this belts". My analysis is that it is a belt-tooth hop-off or tooth-engage vibration, and is due to the small diameter of the drive pulleys and tooth profiles causing the belt to grab the edge of the pulley tooth when engaging or, through stiction, hanging onto the to tooth when it disengages. The artifact repetition is exactly the belt tooth pitch. This is a common problem with toothed belts, and it really requires shaping of the teeth to ensure clean transits, as with gears. Of course, much larger pulley diameters and/or super-fine tooth pitches may reduce the issue. Perhaps you could investigate this further, as I no longer have the resources to do so. Thanks again, Tom, for a great video.

[@riba2233]

I have seen people get rid of these artifacts with properly tuned belt tension.

[@draco10111b]

There is a smooth idler facing the belt teeth for each belt. Heard that may cause issues, but haven't seen proper testing for it.

Fantastic and multi-faceted review, as we've come to expect here. The only comment I have is that I've just built a 350 sized Voron 2.4r2 kit, and I've paid basically exactly 1k € (formbot kit). So the quoted price in the video of 2k € seems a bit steep, even for premium kits like the LDO version. My kit honestly was fantastic, despite the budget price, and even includes tap, can board toolhead and upgraded hotend for that price. No complaints about the quality either. That being said, a Voron kit and a Prusa XL 'kit' are in very different stages of assembly in comparison. I would plan for a week of assembly for the Voron, not 2-3 hours.

[@SentientTeapot2444]

Formbot is genuinely such good value for money. The only things I changed out from their kit were the fans.

Also notably the Sv08 exists and ratrigs exist so the large size isnt really a selling point without the tool changers, especially because the others will be more fully featured with klipper.

@@BeefIngot There's also the Troodon for around 1k € (also from Frombot), which has existed a lot longer than the Sv08, years actually, and is much closer to a "real" Voron. It still isn't a Voron, but at least uses a normal Stealthburner as the carriage/hotend and not something proprietary like the Sovol. Assembly is comparable to the Prusa XL, probably faster and less tuning/setup required, too. Obviously it's also single tool head, like all these examples, as it was just a comment on the price comparison. I don't mean to suggest they are a cheaper Prusa XL (clearly not).

Replace the knob with a mk3s style one for faster navigation 10. replace the two side sensor cables with two bed cables and then lower the side sensors for better cable path (see my videos on this topic).

If you want better results for multi material prints without using the prime tower you just need to tweak the parked retraction distance. Adjust the retraction while disabled setting for each extruder to 11.8mm. It should be in the printer settings tab.

[@suntoxx9667]

You can also print with multiple nozzle sizes in one print, but it disables the prime tower. You can trick the XL though, if you do not tell the printer nor Prusaslicer, that you run another nozzle size. You need to create custom filament profiles for the other nozzle, setting flow and pressure advance and you need to make sure to stick to layer heigths and extrusions widths, that both nozzle sizes support. I made a post about that recently in the fb group called Prusa XL users. It works great so far.

I'm the exact opposite when it comes to print quality vs. speed. I'm only interested in the fastest the printer can print and maintain quality. I've found the structural profile does just that.

[@MMuraseofSandvich]

21:45 This is the point that I think a lot of customers for Voron and BambuLab miss when they say the XL is "expensive". The XL was clearly aimed at the Ultimaker and Markforged prosumer/professional market, and lower cost fast CoreXY printers came onto the scene in the meantime. 5 tool heads at this volume and this speed capability + Prusa's open and supportive ecosystem is a _bargain_ compared to the Onyx One or any Ultimaker, let alone higher end industrial machines from Stratasys or HP. If I had this option 6 years ago when my boss asked me for 3D printer recommendations, I would have said Prusa XL with 2 or 3 heads without hesitation.

A stratasy metal printer is a nother league. If prusa would have aimed for Industrial application one would think you could print abs proper right out the box. Yet it does not even have an enclosure.

I was confused when I saw the speed and acceleration values in PrusaSlicer for the "Speed" profile at 16:17, because I remembered them being much higher.

I can't decide which looks more tedious: installing 5 Prusa XL toolheads or leveling the Orange Storm Giga bed?

[@stonelambert]

Just finished building my semi assembled singletool XL and my second print is finishing now. No hiccups thus far! Super happy with quality, speed, and volume (both audible and print size). Really impressed with the bed leveling capabilities.

[@EK1H]

I have just got my 5T XL up and running. It takes a detailed understanding of how it works to get good results and you must print dry filament, ideally straight from a heated box. It can do multicolour faster than an old Mk3S and waaay faster than a bamboo with ams. Prusa also have excellent support and customer service.

[@MisterMakerNL]

Got this thing at work, works like a beast. Only pulled out a wire when cleaning the nozzle. I o=print 90% of the time in the structural mode, where the seam is on one spot. Which would be not pretty, but production doesn't really cares if it is pretty they care if it is strong and doesn't break. I did not hear you mention one annoying limitation atm. This is that you cannot use different nozzles sized mixed. So if you think you can use one extruder with a 0,6 and the other with a 0,4 then you cannot do dual prints anymore.

[@drstefankrank]

If I have enough space on the print bed, I use the "No sparse layers" for the wipe tower with the MK4+MMU3. It saves a lot of filament, especially if only a few layers have different colours.

[@ProtonOne11]

We are considering getting one to "replace" our MK3 for something a bit bigger and more advanced. One thing i'm not sure about is different nozzle sizes. Is that supported now without issues? So i could have a 0.8mm nozzle for large low detail prints, and the good old 0.4mm for smaller, more fine detailed prints. Swapping around nozzles on a single head printer is always a lot of work with recalibration and everything, so just having another toolhead with a different nozzle ready and calibrated seems like a very nice option.

[@patprop74]

Did i read that right? 14:17 you printed a benchy in 12 minutes with the XL?

[@snuups]

I bought one. 5 Toolheads. I had a lot of doubts in the beginning. Mine came already with 0.4 mm nozzles. lucky me. Since I have it I had no issues whatsoever. It became a workhorse in my shop. Now I am thinking to retire older printers with XLs.Due to the size I can print more parts at once. Less wörk for me. I really like this printer.

[@lilietto1]

I'm a consumer, but if I were a business, the prusa xl would be a no brainer, especially with an enclosure. 4000€ for this kind of capability, so cheap.

[@Krynn72]

I've got a MK3s and a Mini and haven't used either one since I got the XL. It's so much faster than I can print two separate prints one after the other in the XL and still be done before printing one in the XL and one on the MK3s. And the auto first layer cal is amazing and makes it so much safer to just start the print and walk away.

It seems like a printable(?) set of shrouds could be added to the sides of the XL where the filaments reside. The idea is to create two really large desiccant/dryer additions with the outside frame being (re)movable for filament swaps.

[@redkingrauri3769]

I was a early adopter of the xl and unfortunately I got a bad unit. After a month I ended up sending it back. Was my first prusa, but I don't think it'll be the last. They've clearly ben updating and fixing the issues I had and hopefully when I can afford it I'll get the 5 head. That, or I really hope other tool changers become more commonplace. A KZbinr has been making a custom tool changer called the "wp-daksh" based on the xl's system since it was announced and it workswith rat rigs and vorons. I think if it got a little polish and funding it could be the next best thing.

[@gamejunkie7]

There is a voron tool changer project. On a standard 350mm voron, you can fit 6 heads too.

[@Voidmonster]

Having just gotten a multi-material printer, I was just staring down the need to do exactly this experiment. You've saved me a lot of time, effort and filament! Though, I *do* have a roll of Bambu's dedicated PLA/PETG support material coming. It'll be interesting to see how that stacks up against just using PLA/PETG for part/interface.

[@laurencebrundrett9301]

About your extruder 3 height issues. I have a single head XL and it will get the nozzle height wrong if the filament is too wet. A small amount of excess filament extrudes (pushed out by water in the filament flashing to steam in the extruder) prior to probing the bed height. Anyway, the height is set by a bit of plastic touching the bed instead of the normal nozzle to bed. Result is a first layer that poorly or does not bond to the bed. No problem when using filament that is not hydroscopic. This sounds similar to your extruder height issue.

Finally someone is paying attention to the best DYI robot on the market. That guy deserves some acknowledgement for his incredible creation.

[@zihotki]

If it requires perfectly dry filaments to go multi-material, then I'd expect for it to have a dry filament box as part of a printer. Otherwise how would you ensure the filament is dry during the printing in all types of climate? That's something I can't understand when looking at the currently available multi-filament systems.

[@tiagotiagot]

Is there such a thing as a filament drier that got a self-sealing opening you can plug a bowden(sp?) tube on and get the filament straight to the print-head without exposing it to the room air?

[@MadeWithLayers]

There are quite a few boxes like that out there, some even monitor relative humidity inside the box and control their heaters accordingly. The side filament sensors on the XL have couplings for bowden tube on the incoming side, too, or you could disable the side sensors and feed a long PTFE tube straight from a drybox to the toolhead.

[@alphadragon601_9]

23:54 the prusa ethos “I have it so I’m just going to put it to work”

[@fordgeher]

So what I am interested in is if I can sequentially print two completely different materials in different spots with completely different bed temperatures. For example a high temp nylon with carbon fiber and bed temperature of like 100°C and in a different spot on the segmented heatbed a low temp PLA or TPU or so with only 50°C. And what about the problem with different nozzle sizes? To speed things up you could easily combine .8 and .4 nozzles with the same material. How is this ment to be sliced? Currently there is no real native support for that....

[@johnravensbergen3324]

Thanks for the insightful review. I also have the 5 head XL. I am printing PolyFlex TPU90, a 90 Shore A material. I need to "top" load the filament. It would be great if it was possible to turn off the side filament sensors, and only use the sensors in the extruder. This would enable spool join for this setup. Any suggestions would be appreciated.

[@moimeme8827]

did you try support with another material that don't melt with the previous (like PLA vs PETG) ?

[@EIEIOOOOO241]

I've been waiting for this video for months!

[@ProfessorOzone]

Blast! I was hoping for more information on filament. You mentioned that it has to be bone dry, yet the spools just hang on the outside of the machine soaking up moisture( I live in a humid environment). I also generally print ASA or ABS, so I can't leave the spool hanging there for too long. I also need an enclosure. Or do I? Anyway, I still love the channel, but I'm just not sure if this would be the machine for me if I am interested in a larger format than my MK3S+.

Ive been working with the XL 5 head since december. Love it! It has even put our Minis out of work for the most part.

[@TheElectronicDilettante]

First, I don’t yet own a 3d printer but I’m a huge fan of the concept and tech. I see a lot of people having issues loading flexible filament in the feed tubes. Would it be possible to feed a length of rigid fishing line from the extruded end through to the filament, affix the line to the filament, then you’d be able to gently move the filament through the tube. Just an observation through video as I’ve never seen one in person. Thanks for the excellent video

[@SplatusEve]

I love the locking mechanism of the tool heads. Its like a roller-delayed blowback from a H&K rifle.

[@karlh6692]

0.4mm walls and 0.8mm infill? Now that multiple extruders are a thing is there a software that supports fine tolerance 0.4mm printing the walls and then switches to do all the fill with a fast flowing 0.8mm(for example) head? Maybe the infill could also be a carbon fiber filament for added strength without exposed fibers.

[@the78mole]

On my new Prusa MK4, PrusaConnect seems to produce "partly forgotten layers" sometimes. Some other users also seem to have this issue. With PrusaLink or using the USB-Stick, this problem vanishes completely, while the print process is still showing in Prusa Connect.

[@AerialWaviator]

Besides being able to print from multiple spools of filament, is there an use case where having different nozzle diameters could be useful? Guessing Slicer software is probably not really designed for multiple print heads, particularly multiple nozzle diameters (and related print profile). I can see a number of use case where being able to print from two spools would have advantages. example: print material + support material, or 2 colours. Above 2 print heads, it starts becoming harder to justify for the average user.

Nice video! You should try mixing TPU (I use Cheetah) with PLA. I find that I have to design parts that interlock while being printed, but the results are quite good.

[@rcmaniac25]

I have a single tool XL and it's worked great. Some issues and, for the price, I always go to Prusa support. But otherwise don't regret the purchase. But my main rant comment here: 110%, they need to up the speed profiles. Prusa went to lengths to not say machine speeds, and then profiles came out and they were fast but not what people expected for a modern printer. I was told "they're conservative but the machine will fly for faster profiles" but I've yet to see it. I've told people "the reason a Bambu printer prints at 0.1mm layers by default is because it means they can do faster speeds. And if 2 layers, at faster speeds, end up being less then then 1x 0.2mm layer, then you get faster prints AND higher detail" so when the final profiles came out... they didn't do that. Lower layer heights have slower max speeds. They already have a structural profile for when you need to structural parts... but bring the speed Prusa. Secondary rants: they have a lot of stuff going on, but I feel they need to accept some low hanging fruit... control of the light bars on the side (6.0 was the first time they offered any control, and it's just "do you want them to dim, or to always stay on"), single wall top/bottom layer (I don't find this important, but I've seen so many who use OrcaSlicer over PrusaSlicer purely because it has the feature...), etc. Or some bigger ones: please, for the love of all things holy... if you're gonna have some dev sink months into a feature, get us more then 16 cancel objects. It's a hardcoded limit that even Prusa Connect shows there being more then 16 objects with cancel options. Of course, I keep adding more to the rant: For the cost of a ESP32-CAM, they should really include one with the firmware they now tout, and a mount pre-sliced on the USB drive. If the cost margins are that low that one of those can't be included, I have other concerns. And the enclosure... having owned multiple Prusa machines and seeing how people look at a feature list and go "has/has not" I almost feel like they should default their store to the maxed out setup and let people uncheck items to reduce cost. Here's a MK4 Assembled, with MMU3 (pre-assembled?), and a Prusa Enclosure, and a ESP-32... only $1684. Oh, you don't plan to print multi color? It's now $1385... You don't need the enclosure? $1108. You have a camera already? $1099... It's human psychology. Many will instant disregard the printer for that price, but many do without those items included... and others stop paying attention when they find out it doesn't have an enclosure and multi-color and a camera. But reducing cost instead of adding cost has a different mental reaction. Offer the options, get the line items when comparisons happen, see how people react... the power of defaults is strong. So if suddenly that becomes the top selling printer SKU... it becomes now something to tweak and scale in areas so maybe at one point, a XL with enclosure and camera costs as much as an XL without those, costs right now. Ok, pet peeves about XL done.

That was one amazing review about the Prusa XL, well done Thomas

[@BinaryExplosions]

I'd love to see captive TPU hinges in an otherwise rigid print. I can imagine getting it to print will be tough since TPU doesn't bond well onto other filaments, but if it could be printed in the gaps between parts of PLA or PETG it would be a really interesting option

As always Thomas great video. I purchased the Prusa XL with 2 Toolheads some months back, and I built an enclosure for it. This week Prusa announced a 600 Euros enclosure which actually covers with a "black curtain" most of the print area, very odd. And it doesn't even include a camera yet. I am a bit disappointed to be honest, I purchased a Prusa to support the company and what they stand for (all my 3D printing friends got a Bambu X1C for half the price). I would like to see Prusa taking care of us by releasing an enclosure we could 3D print ourselves and add optional accessories.

Hey @MadeWithLayers , that stringing I have (had) too. I've solved it to a lower print temp. Instead of 215 for PLA (I'm using mostly Polymaker) I'm using 205 and that's printing way better (very little to none stringing).

[@RegularOldDan]

Great video and good explanation of the value of the printer. I've had a hard time explaining to others how this printer actually is a decent (even excellent) price for what you get. However, people still look at it in the short term - "Sure, in the long run, my multi-color/material prints will be far cheaper due to less waste... but think of how much filament I could buy to waste with a cheaper printer!" Never mind that such printers w/ a single print head just can't do true multi-material due to the different temperature requirements. In any case, this looks like a great printer, albeit way out of my price range right now.

It's not a TPU-specific machine, but since it's using the one-piece Nextruder nozzles that reach up all the way to the drive gears, it does handle flexibles pretty well. Biggest challenge is getting the filament pushed up the reverse bowden in the first place. 10:08

I think the sweetspot for amount of extruders sits at 3, which Prusa has not included as an option. With 2 heads you are constantly having to trade the features of multi-material support, spool-join and extra color to highlight details. With 3 it doesn't feel like a trade-off anymore. 2 heads leaves more to be desired and 5 is more than you need.

Can the XL use different nozzle sizes in a single print? For example 0.4mm with 0.07 layer height for outer walls and 0.7mm with 0.28mm layer height every fourth layer for infill. I was able to do this with an old MK3 with single nozzle but was wondering if it also works with different diameter nozzles.
