Important to know that the real reason Angus's prints are not affected by being upside down is because he's in Australia and two upside downs cancel out
I'd like to see the same test with a machine that doesnt rely on Input Shaping to see if that's the secret sauce or if it really in general doesnt matter which surface to print on...
Yap my thought exactly. I have a very basic printer and it doesn’t have any calibration/compensating for that at all
@@ynonzohar4199agreed would love to see this!
A bit of a flawed testing technique, he should have used like an ender 3 or prusa mk3 as they are kind of the "golden standard" for testing
This is a really easy test to replicate. test it with your own printer
@@cozmo4694not flawed, just testing something else. In this case: "in the age of competent input shaping, does it matter what your printer is sitting on?" Although, could have spelled it out as such.
It would be interesting to see this on a printer that didn't do a compensation calibration.
Just knowing how input shaping works shouldn't. Not sure how this is surprising, you can hang your 3D printer from the ceiling and it likely won't affect the quality unless there's some specific resonance created. I spent a lot of money on creating super rigid and heavy surfaces for my printers, and I've since moved them all into a rickety folding table, and the results are better. More rigid is good if you have the dampening to counter resonances. Its difficult to intuit because a lot of other CNC stuff deals with much slower speeds and accelerations, but with much greater mass and therefore their resonance frequencies are lower and more catastrophic. I've often thought about creating a cast machine frame (mixture of resin and a very hard filler like granite) like they do for milling machines, but I'm not sure it wouldn't make artifacts worse based on what I've seen experimentally.
A closed system is a closed system.
The funny thing is that that "bad" benchy is what most peoples decent benchy looks like
Emily the engineer did some pretty extreme testing recently too, upside down, on its side, hanging from the ceiling, getting kicked and swung, in a vat of oil 😂. Love these test videos
Would be interesting to see how that would be on a printer that is not individually calibrated for input shaping. Like the Prusa Mk4/Mini that have Input shaping but no accelerometer.
I was just about to comment something similar. The test here was done using a printer that is pretty well setup out of the box. What about running something like a Wanhao i3 or something similar as these weren't the best printers to begin with from the start.. Very curious to see those results. From personal experience i've since moved away from wobbly tables as much as possible and continue to advocate against them.
All hail the wobbly table! I remember when Tom Sanladerer made an overly complex bouncy box to hold a printer to see if it would reduce ringing and... it didn't really do anything, maybe even made it a little worse IIRC. But like you said, this is probably the first time being done on a high speed printer (and certainly first I've seen for a cantilever and input-shapping based printer). Still interesting to see the results. You did the same prints on 3 different env. Would be interested in the extra env. of the concrete slab + checking noise (you commented it was quietest on concrete, but other audio comments seemed to be around calibration instead of the print itself). My mind now wants to see something extra: Given basically the whole Klipper community, and Bambu, have the ability to rerun the calibration for different env. But the other juggernaut in the space, Prusa, has decided... "nah" and does the input shaping calibration in factory. So, using the same A1 mini, if you calibrated it once (say, the concrete floor) and then ran it without calibration in all the same env/test... what are the results? Is the quality the same and all this calibration in each env. a waste of time... or is quality worse, Prusa messed up and I should be demanding an accelerometer from them. If fixed calibration is fine/good, it could open a whole new area where you can take your Marlin-based printer (which actually supports input shaper), have one person do the calibration, and then share those settings around to the rest of the community. Literally turning basically every printer out there, capable of running the latest Marlin, and turning it into a fast printer without needing to Klipperize or mod the printer.
> I remember when Tom Sanladerer made an overly complex bouncy box to hold a printer to see if it would reduce ringing and... it didn't really do anything yes, because Tom (and other youtubers) don't understand where the ringing is coming from: the ringing does not happen because the whole printer is moving! the ringing happens because there is some wobble between the print head and the bed! if you have a perfectly robust printer you can put the printer on the back of a pickup truck and make a perfect print without any ringing while driving through the desert (and that's actually exactly what the designers of the Pantheon Design 3d printers did: their printers use spindle instead of belts and therefore they don't have problems with ringing. to prove it they put the printer on the back of a truck and went offroading (i think this story was mentioned in one of nero 3d or cnc kitchens videos a year ago)))
@@JanMuell42 I literally was just chatting with someone and made the comment about how I'm not convinced the surface a printer is on matters because everything should be relative to the frame, not the table it's on. It's also why I proposed that question of rerunning the rests without recalibrating.
@@JanMuell42 Jup... But that is in a perfect world (or if you have a super rigid construction which doesn't flex at all). In the real world, with the common budget printer, a moving (or 'wobbling') frame is always going to have a certain influence on the rigidity of the printer arms and heads, etc. It is just plain old mechanics 101. (and also, a stepper can only take so much abuse before it starts skipping). So in that sense: yes, outside factors can and will influence it! However, the *real* question is: how much so? That is an entirely other story! If you can compensate for the 'sloppyness' with other means (like input shaping, like frame damping, etc etc), then the perceived change and visual defects would be greatly minimized, if not entirely imperceivable so it seems. Of course, the less you need to compensate in the first place the better.... As with all things, it comes down to nuance and _'what is in the small print'_ I think. I never liked oneliners like _"It doesn't have any influence"_ , or _"doesn't matter"_ . I always want to ask the how and why and see the details, especially when things go against common sense, gut feeling or basic knowledge.
My printers are super-rigid box frame contraptions and they have far less ringing artifacts if I unlock the casters and let them move around a bit. I might be able to change that if I switch to aramid-weave belts. The machines move when the heads change velocity, so eliminating belt stretch (and vibration) might help clear that up.
@@SwervingLemonTom's tests quoted in the comment agree. He printed some springy (much more springy than the stock rubber feet) shock absorbing feet and found those to reduce ringing somewhat. That's why he built the overly complex box.
Kudos for reading the comments and addressing them in a very positive and informative manner. Cheers
Good Job on that video! I build my THE 100 3d printer around a wobbling pla frame to even reduce vibration. It's nice to see that more and more people realise that wobbling does not affect your printing quality and also that it could improve your printing quality especially when printing at highest speeds
This is actually a bit of a concern for Prusa machines, especially the Mk4, which has input shaping so it prints fast - but the compensation is done at the factory, then the accelerometer is removed before shipping. So they can compensate for the printer's own vibrations, but the printers can't calibrate themselves based on the environment. It's one of those decisions that baffles me about Prusa's Mk4.
Well that explains why my prints look like shit since I moved it from my sturdy work bench to my wobbly lack enclosure...
I put a MK4 in a prusa enclosure and got ghosting from just that. the printer just sits on a sheet metal floor that has no support under it. I stuck a scrap piece of 1 inch thick sound attenuation foam under it to support the floor and that helped but not perfect.
I began to notice odd delaminations and wonky exterior faces once I began using the Mk4 on our wobbly table!
I suspect machines not using linear rails for every axis will have worse results. There's a lot more flex in something like a rubber wheel running directly on v-rail. So vibration damping is probably still quite useful for the majority of machines out there.
Excellent video! The speed on that little printer is impressive. I think the slight ghosting could be a combination of both the increased speed and belt vibration. All things considered still impressive prints. Thanks again for the great information!
I appreciate the honesty of reviewers !
Great video! Have been wondering for ages whether my table is actually a problem
3D Printing in space: What are saggy bridges?
Thanks, that was helpful. I've had my printer on a pretty solid workbench but wanted to put my new one on a desktop next to it that is nearly as solid but not perfectly level. Sounds like it wont affect anything.
Very interesting video, Angus. Thank you for sharing. I hope you keep investigating this issue.
Thank you for this, Iv got the A1 and i have it on a VERY cheap Garage shelf that iv put weights on to reduce the wobble, but it still wobbles so much, good to know its not really an issue, even when we are upside down(fellow aussie)
I was running my Original Prusa Mk.2S on a plywood table built into a closet wall, the table was amplifying the printer noise and making it really loud. I used a cement paving tile and a partially inflated air cushion under the tile to quiet it down. This made an incredible difference and now I just hear the cooling fan.
Thank you for running these experiments. I have been curious about all of this too. For an X1 Carbon another thing to consider is how you have the cabinet door when you run the vibration calibration. The first time I did the calibration the door was open. Later I began thinking that would certainly change the dynamic responses since we run the printer with the door closed. So of course, we reran the calibration. I really don't know if it made a difference but still it is more realistic to do the calibration with the door closed.
This is truly remarkable. Thanks for the testing!!
Great video buy I think the real thing someone needs to test is the effect of wobbling on MTBF or other printer wear and tear. As well as stats about model detaching from surface, the likeliness of that in correlation to wobbling
I suspect my Ender 3 Pro won't be as resilient as this printer 😆
My Prusa Mini lives on top of a large Ikea Kallax shelf which definitely has some wobble to it when printing, especially with the newly added input shaping in the 5.1 alpha firmware. I did print out the 16 minute "Bonkers Benchy" Josef Prusa put out with the firmware update and it definitely has some artifacting, so I am now curious as to how well it would work if I printed it on a more solid surface. That said, I've generally had no issues with print quality before the input shaping was added, and prints came out looking nicer than the ones from my Ender 3 S1 that was sitting on the ground.
Just wanna say.... I don't think it's visible with the big stuff you guys usually (test) print, but I print small items with little nobs (smaller than a benchy) that are also ironed on the top surfaces to sell. I always see issues on the little nobs. My 2 bedslinger printers are on the same table as 2 (paper) printers and a silhouette cameo (plotter), and these 3 tend to shake my table when they're working. I've gotten layer shifts when I have them all on and working at the same time. That's why I was very interested in this anti vibration tech by bambu.
I bought the first ultimaker 1 in 2011 when it was still insane to own a 3d printer. i put it on a table and printed a test object. i saw the table wobbling very very slightly and my engineering instincts instantly shouted "this will ruin your print quality". so i put in on the hard floor and reprinted the part, and indeed, it was visibly better. that trusty wooden 3d printer is still there on the floor, printing as beautifully as ever, never replaced a part, not even a belt.
@Angus Regarding the calibration for each "foundation" surface: Does the A1 Mini do this calibration with a head-mounted accelerometer and bed-mounted accelerometer? And if so, does it also have a chassis-mounted accelerometer? Or is it deriving X & Y vibration measurements from some other means, like maybe motor current? The key question is whether their measurements account for only resonances within the machine itself (eg: flexing of the head position relative to the bed), and ignore resonance of the printer-and-table assembly (which doesn't affect relative position of printhead and workpiece). Anyhow, nice video as always!
I love this community so much.
It would be much better to actually look at the parameters that were set by autocalibration in each particular case. Because even if the quality may look similar, effective printing speed might suffer if the acceleration is reduced due to calibration detecting more vibrations (not sure if this is the case for Bamboo autocalibration though, it might only change the shaper frequencies and that would just lead to more artifacts with the same acceleration).
its a bambu, so tough luck getting those variables out of the printer.
I feel like he'd have mentioned if one of the prints took longer?
Hi, tks for the fun video Angus! For the X1C I read somewhere that the printer life is extended if using rubber feet (sold by BL) optional add-ons… I installed them. The table moves less & the printer does a jig. Probably a bit quieter. Do you think they extend printer life at all?
I appreciate the recognition that although it doesn't matter as much, as a communicator, how it looks helps keep the focus where it's needed. This kind of curious dialog between audience and creators is what is most unique about KZhead. Excellent experiment.
Thanks for your tests. In my experience (without input shaping), the rigid and massive base (or the floor) together with a thin and soft layer of rubber to adsorb and dissipate vibrations is the best solution.
What a riot Angus, you have, as always done a super job on this one!
Awesome fun video. it goes to show how much this thing is doing. I am a firm believer of cnc kitchen take on this, and even though Bambu does a fine job of stabilizing. I believe anything you can do to help stabilize a printer will help with print quality and certain noise.
Great video. I vote to keep the wobbly table. It helps the average consumer/enthusiast like me know that the print quality won't change too much even if they don't have the ideal setup. Nice work 👍🏻
Thanks for the interesting testing!
id love to see this on resin haha i thought for sure that's what this weas. filament i get why it's fine. I'm not so sure with resin but then again i haven't the slightest clue
Very entertaining and interesting video Angus. I was worried about printing on a wobbly table and took extreme action too and saw no difference. Back when I was working with large machinery we actually solved manufacturing issues by putting machinery on flexible mounts to let them move more. Physics can be very complex. 😁 Cheers!
I use the concrete tile to dampen the noise from my 3D printers. The 3D Printers were a lot quieter since the vibrations don't make it to the surfaces that amplify the noise (my tables and desks). But like many others, I'd like to see a printer's results without input shaping on the different surfaces.
Was the print speed any different? I mean, does the resonance compensation slow down the speed a bit?
Great Video, and very entertaining. It would be great if you could repeat the test with a bambu p1 or x1 since those have heavier printer heads and a different movement system.
My Prusa mini also printed perfectly fine on an unstable desktop, although that was an accident, and it didnt seem to be as noisy as the A1 mini. Im very satisfied with it
Amazing results
I'm very glad to see this test in the way you did it Angus! And also the comments you make about all this. It DOES confirm that vibrations/wobbly underground DOES have an influence on the print quality! It makes sense, it passes the smell test, it confirms the gut feeling. I have seen many people/youtubers in the past stating otherwise. Stating it doesn't matter at all. Which doesn't sit right with me; I always had the feeling: it doesn't mean that if you can't see it with a quick test, that it isn't there.... And your test confirms this thought. However, it also shows that with 'normal' usage, those influences are extremely small. Up to the point they are as good as imperceivable when you use an ordinary decent normal table or underground. And all this taken in account that with the printer you used there is input shaping/frequency calibration being done. So, I suspect, without such a 'modern' feature, the result might be a little more pronounced. How much so? Accordingly to those 'older' test from those 'random' youtubers, not much more difference either. But I strongly suspect it does have a bit more influence. Conclusion: use any decently stable enough underground, but you don't need to go overboard with it; a normal table will do. (unless you're of the kind who paints flames on the car to make it go faster.... in that case: go all in, it will not hurt :-P )
Thank you great job
Thanks so much! I have six P1S printers and I still haven't made a desk for them yet out of fear of vibrations from one printer effecting the others. I've got a couple on concrete slabs and I think I'll buy a big multi-shelf unit and just put all the printers on the concrete slabs. Thanks for the video!
a very good test to try remove the fans from the head gyroscopic precession causing ghosting I tried it but could not get conclusive results...I have not suspended it from the ceiling to amplify the issue though kept the mod though
This was an interesting video for me because when I was getting into printing, I always heard that printing on wobbly tables or non-level surfaces was bad for quality. Despite this, I set up my first Ender 3 on a 120 year old table that belonged to my great-great grandma. It is a beautiful table, but it was so wobbly due to the table's connecting joints becoming loose with age. When I got my second Ender 3 a year later, I upgraded to a much sturdier table that could fit both printers, but I found no difference in print quality, leaving me questioning everything I had heard about wobbly tables and non-level surfaces.
I appreciate the convenience of a pre-assembled printer, but Ive heard concerns about the A1 minis size
Nice testing! I think I fond more ways to improve the quality of Prusa mini~
This is the exact video i was looking for! Thank you! I just bought a 3d printer and Ill be using it in a trailer 😅. I wasnt sure how that would affect print quality
A neighbour left an aged parasol base beside their driveway. After it wasn't collected for a couple of months, I took it, drilled out the wobbly steel upright (obviously the reason it was thrown out), cleaned up the slab, slipped it under my printer, and it made a world of difference. Being decorative granite, it look gorgeous on my worktop. Since the top side is highly polished, there's no cable abrasion, and the printers rubber feet grip it nicely. As you say though, the big thing is how much quieter the whole printer is.
Curious to see the same thing with a direct drive head (heavier, so probably more sensible to machine vibrations). Personnally I found my Ender 3 S1 Pro prints a bit better switching from my wobbly desk to UNDER the wobbly desk lol, directly on the floor.
I didn't know that model printer has resonance compensation. That's neat. Calibrating for the resonance is a smart idea. Now I have to see if my printer (sv06) has that.
I have an elgoo neptune 4 and put it on my heavier desk in comparison to my flip up desk to the side of it. I was worried it would get too wobbly but maybe I didn't actually have to do that. I don't have vibration compensation though
I'm curious if the movement of the printer could improve print quality on the x axis specifically on tall objects where the acceleration can cause the print model to wobble forward and backwards
i got a neptune 4 recently, first printer, and it is proudly a member of team floor printer. I had trouble even after bracing the table on 3/4 sides with wadded up socks. Eventually just put the table on the ground and printer on that. Dunno if it truly helps, but it makes me less anxious lol.
I had my X1C on a bench that wasn't completely supported on the front edge, it was attached to the wall so I figured it would be fine...Then I started Printing and It Constantly threw resonance errors till I supported the front edge of the bench with a random pile of things I had around the house. So I have to say it makes a difference.
I think the main problem is the calibration sequence on a wobbly printer. The goal is to measure resonances within the printer structure (e.g. between bed and toolhead), but measurement is done with an accelerometer which will measure overall (unintended) movement of the toolhead - even if some of that is the whole printer structure moving. This of course depends a lot on the actual resonance of a hanging printer or an unstable desk and if/how much the calibration sequence ignores such low frequency resonances.
I think you’re onto something, solid mounted printer will measure vibrations on the tool. When it’s wobbly the frame will also move in the opposite direction but that’s not being accounted for.
Usually "louder" is because the table top is acting as a sound board Hanging that printer from the gantry column probably was not the best option . The joint at the base of the column was designed to support the weight of the column and the gantry/print head. Hanging the printer from the column makes it support the base , power supply , electronics etc - much more mass and the joint flexes more. It would be better to hang it from the base using a cradle of cords or bungies from the corners of the base.
For the suspended one, I suspect because of X/Y movements, you are -mixing- the resonances between the two axis, while the software only compensates for the resonance of a particular motor on it's own axis, also that violent shaking is likely causing Z bounce which further cuts into layer accuracies, but it hardly shows that.. Maybe if a fast cylinder was printed like that. One slow layer, then a fast layer, then a slow layer.. but that's oddly specific. But the idea is that fast layers would squish and spread in areas due to XY messing with Z. A cylinder at just one speed would be mostly uniform in those distortions, so harder to detect at only the first layers.
We need a restest with prusa mk4/mini/xl with input shaper, since they use the accelerometer in the board to negate the wobbling
Did print times change at all? Usually Input Shaper will drop accels if things wobble too much and increase print times.
I have a FL Sun Q5 on an old end table printing at 60 mm a second and it prints just fine
I would like to know how this would effect different types of filament. Especially TPU, PC and ABS. Though suspending a fully enclosed printer I assume would be a challenge.
nice video me im trying to findt out why my temporter in the printer off mine is going up and down when i print i cant feel the air flow around him so its not that but i think more of that the termostate is broken off my ender 3
Great stuff, I've been wondering about designing & printing some 'springy' TPU feet for my Prusa i3 Mk3 to isolate vibrations from the surface (table) it's sitting on to reduce noise like it's sitting on the floor.
It has been tested, it's exactly like hanging.
You have to dissipate the vibration, has to be both springy with high histeresis, like car suspension. Put the printer on a sheet of light rigid material+ pu foam below does exactly that
@@dtibor5903 Thanks for the replies, I'll have a search and see what videos there are for dampening the noise. Most of my designs are small, usually in TPU that print in less than 30 minutes where the engineering than the final look of them, so ringing artifacts isn't a concern. You can see what my prints look like on thingiplace username Haku3D, I've 600+ followers.
Its great that the A1 mini comes pre-tuned and pre-squared, but Im still debating its noise levels.
Quality for hangin in the air looks pretty awesome for what it is 🤘🤘
❤Super interesting. Mahalo for sharing!😊
I wonder if the suspended in air showed slightly more artifacting because the printer was tilting back and forth roughly around its center of mass, as opposed to shaking back and forth along the the x and y?
For some reason I've always loved the little cantilevered printers and always wanted a Cetus, but man I adore that clear A1!
Also you should try suspending a second printer from the first suspended with both printing to see if quality gets substantially worse. 😂
When I saw the video title I thought you meant "Wobbly print bed". Your test was well worth performing.
A wobbly table is ok if the printer has input shaping imo. (I'm the guy who gave you the maker coin at LTX!)
i sorta tested this in 2019 when i got my ender3 - i put it on concrete, on tile, and on the space i planne dto print on - and didn't notice a single difference, so it helped me realized "ok so..... it doesn't do anything but dampen sounds" which were quite different.
One of the early anto resonance mods was to put the whole printer on freestanding linear rails, so if anything it should improve
4:00 I still use the concrete paver trick. It keeps it from being so loud
I think the problem with the hanging test was actually just the point of the printer you hung it onto. If my logic is correct, the print quality should be just fine, if you hang it from the base, for example using 4 strings or some kind of hanging gantry
The top of the gantry is generally one of the strongest points on a bedslinger, so I think it would be a valid test. In fact, the instructions on my Prusa Mini actually tell the user to hold the printer by the Z stepper motor at the top of the gantry when carrying it.
@@thesledgehammerblog I think you don't get the problem. The issue with hanging it up on that point is, that the swinging weight flexes the gantry, therefore creating an inaccurate print. This flexing is well within the flexible deformation limits of the material and therefore not a problem when carrying while turned off. Running it like that leaves some ugly artifacts though, which have nothing to do with vibration.
It would be good too see a 3d scan comparison. Definitely a perfect example to show off the differences.
This makes me feel much better about my setup lol. Here I was worried about perfectly leveling my workbench 😅
It looks to me like hanging it probably added more artifacts due to the flexure of the arm and not the wobbling in space. You could try hanging it from the ceiling but rigged to the base instead of the upright if you were wanting to narrow it down a bit.
I've definitely had issues with vibration. I have an X1 Carbon and had it on a small cart on casters, so it wobbled a lot. The parts looked great, but were off dimensionally (printing honeycomb wall parts - they couldn't snap together). Put the printer on the floor, and the parts are fine. Took the casters off the cart, and it prints fine too.
I wonder If the machine hangging balance 4 corner will be what happen?
I'd bet that in this case the "more noise" is because the drivers have to actually supply more power. It would be interesting to see what a watt-meter shows between the three.
What is your reasoning that the drivers have to supply more power?
@@conorstewart2214 Possibly because the drives now have to contribute to the machine's inertial motion in addition to the normal axis inertia.
@@keithcress1335 Now they don't as the only thing they need to drive is the relative movement of the printhead or bed vs the printer's main body. The global movement of the printer is irrelevant (well apart from how that might cause waves of deformation going through the printer and the printed object, but apart from tall narrow prints, I think that effect will be minimal).
@@keithcress1335 the force on the machine is a by-product of moving the tool head, if anything the steppers dont have to work as hard as on concrete. also its definitely not the drivers, modern stepper drivers are the quietest part of any decent 3d printer, regardless of load
the table surface itself also acts as a speaker panel basically. sorta like those resonance speakers that can turn "anything" into a speaker. as even though there is a arm supporting the table surface, there isnt anything else to dampen the noise. if you were to add eva foam under the table even, it would make a big difference and that's not even with direct contact with the printer itself. it's how i dropped quite a few dbs from mine.
You mad man. Honestly impressed with that hanging test
It's a little tank tbh!
@@MakersMuse I have a fun little test with it for this weekend for the ERRF conference
Interesting. I have been curious about this. I have put my printer on the floor (carpet)during speed runs and have managed slightly faster accelerations before layer shifts. My difference is i didn't calibrate input shaping when moving it. I feel input shaping helps a lot in this situation. Would like to see it without calibration.
What are the actual resonant frequencies that input shaping accounts for. The wobble is probably at a lower frequency and/or harmonic than the printers resonance.
thanks for doing this lol. I have a klipperized kobra max on a folding table and its just wobblng all over the place
I usually do the input shaping test with the printer on the floor, and do the printing on the table. My theory is that it will compensate for the movements caused by only the printer, and not also because of the table. Once that's done, the printer as a whole might move the table but it won't affect print quality. Can you do an additional test? Calibrate it on the floor, and print while suspended. I reckon you'll see very little difference between the floor and suspended results.
oscillations are tricky things. sometimes its about particular harmonics creating interference nodes at inconvenient locations rather than raw displacement
That's quite interesting. We have a Raise3D Pro2 here at work, a 44kg machine which is quite a bit heavier than your usual hobby printer. It shakes ever more violently since we print faster with it, so does the table it's on, which isn't the sturdiest. I'm designing some feet with TPU dampeners to put it on as I thought this cant be good for print quality, I'm curious how that will go. We'll also upgrade the table perhaps. ;-)
would 2 printers printing on the same wobbly table mess up each other? I think I ran into that, at least during probing.
I would like to ask, if I change to another type of filament, will it affect the printing effect? this is too expensive for me
You should see Emily the Engineer's video where she hangs an Ender 3 from the ceiling by a single piece of rope, while she swung it around. The benchy came out pretty much perfect!
LOL I'll have to check that out!
Fun and interesting results. Can't say that I'll be looking for a wobbly table for my 3d printers. I was thinking about putting one in the back of the car with a power station and run a print while driving around town....🤠
Ive been eyeing the A1 mini, but the lack of open source compatibility is a concern for me.
My guess is the effect really comes down how well the printer is put together. If you have some play or backlash in the components, then the effect of the wobbling will be way more pronounced, as it will exaggerate them.
I had an anet a8 on a boat at I would work great even in rough weather
I have my P1P on the same table as my Photon Mono, but I don't typically run them at the same time, but I was running them both recently, and the vibration from the P1P caused the print on the photon to fall off the supports and fail the print
Two (2x) A1 printers inversely opposed mounted on a bracket, printing identical models in perfect synchronisation suspended from an industrial spring. I’ll wait for the follow up video!
