Loving your XL reviews, you have been fair, consistent, and touching on the points I'd care about. I finally got my 5 tool head XL and built it last weekend. Easily the longest calibration I've dealt with out of the box. However, after watching everyone else's oopsies the first benchy and key rings were perfect. Just got my spool of HIPS filament and solvent. Looking foward to some HIPS/ABS tests. Next is using a 0.25mm nozzle for either just the outer layer, or spot printing where their is detail/text and/or the top layer printing. If I can get 0.25mm detail, 0.6mm interior/supports and dissolvable supports I'll get my ideal.

Is there anything you're looking to see? I think it does 'work', there are just some things to look out for. But I've been using it pretty much non-stop since I got it and it's basically a larger MK3 with a tool changer and more speed.

The XL has so much potential. They could do dynamic input shaping with the accelerometer, spaghetti/clog/failed object detection with the load sensor, support for a webcam, etc. It looks like the main bottleneck is the firmware team. Every exciting feature released is coming from them, but they are the slowest to do so.

Yeah, I think that's a fair take. The hardware (aside from the networking) is good. The printer is robust and the tool changer is rock solid. I wish more people would focus on the positives. The tool changer has been FLAWLESS. It swaps heads without skipping a beat. I think once the firmware is dialed in and we get REAL input shaping, it will be quite the machine.

Sadly because of the big backlog of orders the focus is more towards that, which i understand. But it will delay my upgrade options for some months now.

the bambu is literally twice the speed of the prusa, because the prusa hotend has half the max volumetric flow rate. this is simple physics, and thats pretty straightforward. width x height x actual speed = flow, and the flow on the bambu before you cold core or underextrude is roughly double a 0.6 nozzle prusa xl while only using a .4 nozzle, and will push further when you up it to a .6 nozzle. people keep comparing apples to orange profile settings instead of measuring the actual machine capabilities and its a bunch of nonsense. the only way the XL can catch up is with a hotend swap to a higher flow hotend with a longer meltzone. if you do a hotend swap to something like say the new dragon ace, with a bozzle, you could outperform the bambu on an xl in terms of max limits on net part speed vs a stock bambu this would be roughly comparable to a bambu with a modded hotend running a cht nozzle. neither printer is limited by the motion system. prusa cant do magic, physics still exists, prusa needs an upgrade to their hotend, its that simple.

This is such a hard question to answer and I'm not gonna touch it with a 10 foot pole! It's a TOUCHY subject.

I think the best analogy is photography. Are you looking to buy a fancy camera body and use it in manual mode (Prusa) or do you want to get the fanciest tech out there and just shoot in Auto and let the camera do everything for you (Bambu)? The XL is VERY different from an X1C. If you want to print pretty colors and don't care about engineering or mechanical parts, go Bambu. If you want to try strange things and push the boundaries on what can be done with 3d printing, get the XL.

@@RobertCowanDIY It's not that hard really... Pros for the XL If you need the bed size and the much faster filament changer AND get the XL dialed in it can be a pricy winner. Filament changer is about 10-20 seconds on the XL vs 90 seconds on the Bambu. Pro for the Bambu You can always slow a fast printer but you may not be able to speed up a slow printer. THE CLOUD IS OPTIONAL for bambu printers if you want a bunch of extra features like cellphone access/control or printing without using a slicer with makerworld. After initial setup you can go completely offline or use a very functional lan only mode. For the money you can get at least 2 bambu x1C with ams and A1 mini with ams or 4 p1s with AMS for the cost of an assembled 5head XL. You can get a print farm up and running with the amount the prusa XL 5 head costs all while handling 4 rolls of filament on each machine. Bambu with an enclosure can print more challenging filaments vs an open air XL printer.(unless you enclose it for more $$$) Or you can print with 1 machine that is still in beta/alpha firmware. Oh and the biggest elephant in the room. If you order a Bambu printer you will have it in less than a week. As for the XL you should have ordered it years ago.....otherwise you will see it in 2024.

Yet an "old tech outdated" bedslinger MK4 finishes prints in the same exact time. The XL will be the same. I mentioned over a year ago the time differences I got between the X1C and my MK3 were minimal when using all the same settings. And the BL fanboys couldn't believe it and said I was wrong and just told me to print more benchys and crystal dragons. Your conclusions in the end matches mine.

I would argue that the Bambu 0.20mm Standard settings are perfectly adequate for the type of model that you demonstrated. I understand what you were trying to show by adjusting the slicing settings to get them to the same mass, but to me this shows far better optimization of the Bambu profiles. "Prusa is coming at it from a different angle" sounds like a bit of a cop out - for this type of model the Prusa profile is just wasting material. For the record I enjoy your content - just an observation!

Best would be swapping the nozzle on the prusa for a 0.4 or swapping the bamboo to 0.6 Then it would be a 1:1 comparison. Comparing by printed weight is the next best thing.

No its not wasting material it has a 0.6 nozzle by default in comparison to 0.4 bamboo. If every wall is way bigger of course it will print more filament.

You are 100% right. I don't usually print stuff like this, but the 2.5 hour part would have been the better application here, no question. I don't agree that 'coming at it from a different angle' is a cop-out. I print a lot of mechanical or functional parts, and the Bambu profiles are fairly weak. It prints too little material and too fast (poor layer adhesion). The print profile are aimed at cosmetic prints, not functional prints. If I was just printing cosmetic prints, the Bambu is the smarter one to use. For the record, I have both and just sold my MK3 in favor of keeping the X1C. I don't dislike the Bambu, but it's been far more fiddly, but it GREAT for rapid prototypes. Also, I saw another comment from you, but it seems to have disappeared, I was going to reply but it seems like it's gone now. Thanks for the support!

Yeah, I'll try that. But I really just want to get back to actually making stuff. As much as I like comparisons, I'd rather just use the thing :-)

Crikey im very surprised the state at which this launched. I have an e3d tool changer with 4 tools and while it is a bit rough and ready it seems to print better than the XL although probably not as fast. I really would be expecting a heck of a lot more from a Prusa XL. Im puzzled why the launched this early if they still have issues. Its still on my roadmap to get one eventually, but by the time it will be available im pretty sure there will be a lot of competition from other providers.

They did address this in the blog post. In short, I think they sell to a lot of government/EDU customers who are picky about open-source stuff hanging out on a network. From my day job, we fill out forms from large companies every week; they want to know what libraries you use, what talks to their network, if cloud is required, etc, etc. There are security risks when you just slap a raspberry pi on a network. For most hobbyists, this isn't really a concern, but for industrial customers, it's something to consider for sure. This is largely why Bambu came out with the X1E, they were probably unable to service that market.

@@RobertCowanDIY Good point. I believe if a hobbyist is using this / non governments, klipper seems like a better place to go instead of using Prusa's own firmware.

the bambu will always be more capable than the prusa. this is really simple, its the max flow of the hotend. the bambu hotend has a better meltzone and can handle more than 2x the flow the prusa can. width x height x actual speed = flow. any two printers running the same speed, accel, widths, height should be exactly the same "print speed" on outputs assuming the motors have sufficient power, not losing steps, etc. the motion system is better on the bambu's and the hotend is better, its always going to be faster, and thats never ever going to change, unless prusa releases a high flow hotend. when i asked jo about it at ERRF he blamed e3d for there not being one. input shaping will never make a printer faster, it smooths the motion curves out to reduce ringing at the expense of smoothing out surface detail. on klipper and RRF printers this is tunable, but on prusa and bambu, this is not. the bambu will auto set the midpoint for input shaping models, but currently prusa is just setting to a fixed point. in order for a universal fixed point to be valid, because your accel performance is going to be build/printer specific iin conjunction with the exact surface and positiong placement, like a fingerprint, they are going to have to be using a very wideband and high smoothing model to account for this, which means lots of smoothing potentially. if you want to print faster, only the hotend can lift that cap. typically you can kludge a hotend to have a bit higher flow by moving to a fatter nozzle and changing the backpressure at a given flow rate, and thats an impact on the classic 3d printing paradox of speed (being able to print faster by going taller or wider but actually moving slower while at an increased flow rate, and being able to extend this with fat nozzles) but on modern printers this isnt really necessary because you can push 0.8 easily on .4 nozzles with modern geared extruders so this makes comparing things apples to apples pretty straightforward. when you use equivalent nozzles. a .6 on a bambu will push something like 32 cubic if not more if the hotend is sufficiently hot. a .6 on a prusa xl will push something like 15 on the same material. its just not comparable. you can push these printers any width/height/speed you want as long as you stay under the flow cap, but the bambu is going to be about twice as fast any way you dice it when you actualy do an apples to apples comparison. all the input shaper is doing is smoothing the surface as a way of mitigating ringing. its not making the printer faster. it is making the printer quieter. you can print at the exact same settings with and without input shaper, the only difference will be ringing performance and noise. so because of this, no, the prusa mini is not magically suddenly faster, nor is the mk4 nor xl. you can run those exact same speeds and feeds before. how do you compare printers in an apples to apples context? you compare how fast you can move the motion system before steploss, max flow with same nozzle size, put a bowl of water under the toolhead at a fixed distance to measure the cooling, look at the spectral charts from a nozzle mounted accelerometer to understand the ringing behavior/performance and how that limits accel vs quality. nobody does this. and thus every pritner comparison on youtube is just....wrong. you should always get the exact same time with the exact same settings......on any two printers assuming they can handle those speeds and feeds in the first place. the physics isnt changing, you're setting it to some accel, some velocity some extrusion width, height etc. where this might vary is between different slicer families where the slicers make different assumptions. this is most notable with slic3r derivatives (PS/SS/bambu/orca) vs cura engine stuff, as they make completely different assumptions about the actual shape of the extrude line. if you use the same slicer and same slicer settings on both printers you will get the same result unless something is wrong, excluding things like startup sequences. you can also use something like klipper estimator to digital twin a slice vs a fw config to actually get an accurate print time estimate as prusaslicer is notoriously and comically wrong the faster you go up in accel, something thats been known in voron, annex, and ratrig communities for years. .

@@RobertCowanDIY at this point I'm probably most comfortable with my voron 2.4 and trident. I first built the 2.4 in early 2021 just before the kits era, and was an early adopter of moving into like custom metal parts, 2.5 amp motors, 48v, and extreme flow hotends, so they have been continuously modified over time to be purpose built for my workflows, very fast prototypes and batching small functional parts.

The xl is not even close in speed to the bambu. The bambu can print high speed and accurately. There is no comparison between the two with accuracy and speed. If the xl could even reach the speeds of the bambu, I am sure it would not be as accurate. The bambus have great motion systems.
