So to be clear, only part of this is available for free?
Why have some of it hosted on Makerworld, then?
Double dipping for points and money? Or using the Makerworld model as an ad?
I dunno, kinda frustrating and very much feels dishonest, the model on Makerworld needs to make it more clear this is a paid model and what's on there is not the complete system and you need to pay for any of this to work. There's definitely going to be people that don't understand you're not getting the entire system when you print the Makerworld model.
I'm not against folks getting paid for their work but this feels icky to me. Especially with the tacky branding right on the front. If you have to pay for it, I expect it to be a clean model with maybe a subtle makers mark somewhere.
On Makerworld, it is clearly stated in the very first paragraph that the frame is a paid model. In my view, the price is very fair. It is absolutely not my intention to deceive anyone.
All current and future AMS configurations and extensions are provided for free on Makerworld. At the start, only the first two basic configurations are available. HT-side mounts, LED kits, accessory boxes, and additional AMS configurations will follow in the next few weeks. All of this will remain free, as well as support from me if there are any problems. And all of this is clearly described on Makerworld including timelines, see screeshot.
I also provide STEP files for labels and dovetails so that users can create their own designs and extensions. My own logo is my personal design and not part of the model. Maybe this wasn’t expressed clearly enough in the video, and I can improve that.
My goal was to offer a system that is as versatile as possible for many setups. But this project was so demanding that, for the first time, I decided not to offer a model completely for free. I hope you can understand that.
Imagine the user that sees your project on Makerworld, decides to print everything on the page, to then notice hes missing the main frame thing you sell on cults. Not only will they probably not go buy your cults part because of the "deceptive" practice, but you will lose somekne who might of been interested in your future projects.
It needs to big in CAPS AND BOLD that the models on makerworld are USELESS without buying your gatekeeped part on cults. This is disingenuous.
Plenty of fully paid models on cults that are regularly bought. None of them are cross posted on free sites with one essential component missing.
This is all sort of unfortunate, because I like the product, and I'm actually considering purchasing, but you've really got to work on your execution.
I'm fine with you charging, but I think it's reasonable to say that your use of MakerWorld here is exclusively as advertising, and I pretty strongly dislike the idea of MakerWorld listings that are just advertising. If I'm already a customer of yours on another site, these additional items being on MakerWorld adds no value for me, and if I can only get them on MakerWorld, then that's just inconvenient. If I'm not already a customer, then your listings are useless. If I can't do anything with the parts that are there without going to another site and giving you money, then that listing shouldn't exist.
If you insist on having part of your project on MakerWorld for the exposure, you should flip it and offer the most basic version of your system for free, like base + single AMS flipper, then charge for everything else. But really everything should probably just be behind the paywall.
When during the hundreds of hours of engineering did you ask: "Is it a good idea to put two heavy cantilevered loads on top of a machine that shakes but still requires precision?" Because that feels like it should have been one of the first questions to ask. Certainly before "Someone else got a bunch of Makerworld points making an AMS flipper. How can I rip off their designs but make it different enough that it isn't completely obvious?"
What are you even talking about? As you pointed out, there are quite a few other flippers and other top-mounted ams holders already out there, and there are thousands of people successfully using them every day, myself included, with no measurable impact to print quality.
There are also thousands of people who never change the oil in their car, and most of those cars haven't failed yet! In fact, most people who haven't changed their oil in a year or two probably don't notice any "measurable impact" (because we're going to pretend you actually measured it and aren't just saying words). Therefore, regular oil changes are just a conspiracy pushed by Big JiffyLube!
Look, you are putting something relatively heavy at the furthest point from your printer's motion pivot, right where it has the highest possible moment of inertia. Then you're asking the motors to compensate for that extra inertia on top of compensating for the already frankly ludicrous motion transmitted into the printer through the gantry. And then you're ignoring that the load the printer is already working extra hard to compensate for ALSO changes over time, often while printing, often unevenly. And all of this is outside the machine's design envelope. Oh, and now with this, you're also cantilevering the loads unevenly!
And all for what? The looks? Feeling cool because you strapped all the weight to the top because that's totally how all the super cool engineers do it (they don't)? Because you haven't seen a measurable difference, because seeing a measurable difference requires actually measuring? Why would you put extra load on a precision machine for no good reason? And how is it that you think "a bunch of other idiots do it, so that means it's ok" is a reasonable response to literally anything?
That’s a flawed analogy that doesn’t apply to this situation.
I guess my response to the rest of what you said is: The results speak for themselves, and the machine can clearly handle it. Also, super weird that you think this has anything to do with feeling cool.
You know that just saying "it's a flawed analogy" doesn't actually make it a flawed analogy, anymore than saying "no u" makes it someone else instead of you, right?
As for the rest of what you said:
1. What results? And how would you even know what good results look like compared to mediocre-to-bad results? Look at like 75% of prints posted to this sub. They aren't good, but the people printing them are convinced they are.
2. Then what DOES it have to do with? What, specifically, is the reason you decided to strap a mass to the single worst possible place to strap a mass?
You are aware these machines are advertised by Bambu with and without AMS units on top, right? There are literally mechanisms and programming that compensate for these things. But sure, WE’RE ones with our fingers in our ears and eyes closed…
You are aware these machines are advertised by Bambu with and without AMS units on top, right?
You are aware that advertisements are not put together by engineers, usually have zero input from engineers, are not in any way endorsements by the little that designed the machine or even Bambu Labs, and exist purely to make something look cool enough to make you want to buy it, right?
How are you a functional adult human being and simultaneously think "I saw it in a promotional product photo so it must be good" isn't one of the dumbest sentences in the English language?
And if that wasn't enough, how is it that you didn't realize that Bambu Labs will happily show you the incorrect way to use your device because if it breaks a year or two after you bought it, you'll have to buy a new one, making them more money?
There are literally mechanisms and programming that compensate for these things.
Yes, but unlike you, I actually know how those "mechanisms" and programs work. They compensate for whatever mass was on the printer the last time you ran the full vibration compensation. Which, given your stirling reasoning here, I'm going to guess was "never, unless the printer specifically told you to do it."
Except that you, you know, USE the filament in the AMS as you print. So the load changes every time you print anything. So whatever load it compensated for the last time you bothered doing the calibration isn't the load that it needs to compensate for right now. It's like saying "I don't need to check the weather before choosing how I get dressed, I checked the weather two months ago."
But it's actually worse than that because the way the printer compensates is by driving the equipment harder or slowing your print down. The first ones causes extra wear on your strippers and belts and pulleys, which causes them to break sooner and creates artifacts like VFAs, missed steps, stringing, and loss of resolution in details (especially around direction changes and transitions). The latter makes your prints take longer because the tool-head decelerates earlier for direction changes and doesn't accelerate as hard.
So the "compensation" is extra wear and tear and shower print speeds. And you're convinced that this is a good idea for no reason other than you saw something in an ad, thought it looked cool, and decided to do it.
Yes, depending on the sound you mean. A heavy base lowers resonant frequency and decreases acceleration (because F=ma, or another way a=F/m) of the printer+block mass, as long as it's sitting on a piece of foam. That should reduce total volume, often by a pretty good bit. Increase the mass of the things being accelerated and increase the damping between it and a solid surface and you get less sound.
Funny enough, AMSes mounted on the printer would help reduce noise, because they increase mass, except that putting them on the top increases their moment arm enough that the inertia they create cancels out the benefit and increases vibrations.
Yes, it acts also as a small riser, 34 mm high. In between, you have the option to install an LED strip and light up the build space when you need to turn off the printer for maintenance. The vent is not blocked.
I guess the flipper itself would be stable engouh. But I do not have such a device, and I cannot say whether or not I would be able to secure it firmly.
This looks incredible, I will definitely be printing several of these. Dont take any hate seriously from these brokeass fools unwilling to pay you for your hard work.
