Well, so I bought the Ender3, but can't say it's a good buy ....
To be honest, I regret it very much and am thinking about getting rid of it.
I have had the printer for over two weeks now, and have been leveling the bed every night for two weeks.
I have already taken the printer apart and reassembled it with a square hook, but that does not help.
If I think that the bed has been leveled correctly and again prints a test print from here, the second print does not go well ....
Yes, I heated bed (45 degrees C) before leveling.
and I already have several youtube videos where they say, leveling is an easy job ...Does anyone have a tip?
Or is choosing a different 3D printer a better idea?@dzjr I don't think you mentioned exactly which problem you're having, but maybe try a different (better) print filament. They're not all the same, and maybe you got unlucky with whichever one you picked. The good news is that whatever problem you're having, there are known solutions on how to fix it.
The learning curve can be pretty steep if it's your first 3D printer. AFAIK, none of them are yet at the level of just unbox and print and never have any problems. Maybe that's why the big companies like Xerox, Canon, HP, and the rest aren't yet offering much in the way of consumer level 3D printers? I've been curious as to why they haven't jumped in to the market. I would think that professional level design from someone like, say, HP, would utterly blow away the mom and pop products that currently dominant. I have a Prusia printer, and, no offense, it looks like it was designed by sophomore college students who had only pocket change to pay for supplies. It works, but I have no doubt that a good team of engineers could design something better, faster, cheaper, more accurate, more reliable, more elegant, and easy to manufacture in volume.

If they ship the Ender 3 with the same bed as they did when it was still in "Public Beta", there's a good chance that it isn't flat at all. Mine had a wide and deep dip in the center that warped inconsistently when heated. Creality was kind enough to send a free replacement heat bed and build surface which was level.
I still added a glass plate (IKEA LOTS mirror tile, 8 EUR for a 4-pack) on top, because I think it is a better print surface than this rough and grippy BuildTak stuff. Prints are super shiny on the bottom side, they adhere well and come off with just a gentle touch if you allow them to cool down after the print has finished - just clean it regularly with soap and water. I didn't even need to level the bed again in years of regular use.
Another solution might be to get a bed leveling sensor like the BLTouch and flashing a suitable firmware like Marlin on the Ender. It'll detect any tilt in the bed or uneven surfaces and compensate for that in software.
@BearWithBeard Thank you for your response,
I do notice that the print nozzle runs free on the sides, and gets stuck in the middle ....
and that the back seems more stable than the front, the springs behind are much tighter.
I will visit IKEA next week and purchase the LOTS.

@NeverDie
The main "problem" is that I just cannot get the bed stable, I will get an IKEA LOTS first, and I will take the printer out and assemble it again.I understand that the printer needs to be adjusted, but I am a little disappointed that the YouTube videos pretend that it is a job of 5 to 10 minutes, but it takes more than 10 days for me ...
Apparently I put something wrong together, I will watch the CHEP video again.I'm going to take the printer completely apart and then reassemble it piece by piece, and then I'll post the result.

@dzjr Your build surface needs to be as flat as possible. You can easily check it with a straightedge: if you can see daylight under the straight edge in any orientation, then it's not flat enough. I don't know how Ender 3 does it, but on the Prusia there are extremely strong magnets that grab the build surface and flatten it against a fairly thick (and very flat) PCB (which is where the heating elements are).
In theory you could also overcome the problem with very extensive bed leveling (as is common in CNC'ing PCBs), but that's a slow process, and you're better off not having to resort to that.
Good luck!

i have checked the bed, it looks like it is not flat, also the horizontal profile is not flat.
i am now trying to sell it.....

Like many, I have been mulling about getting a 3D printer for years. Finally it seems they are getting to at least decent quality (maybe?). Well, certainly a lot of the trail blazing has been done, and prices come down a lot... So maybe it is time finally.

This is very interesting. One of biggest features of Prusa i3 mk3 I have seen is that very clever spring steel bed that you just pop off and bend and the piece comes right off. I have read all sorts of stuff about hairspray, etc. and it all seems like such a hassle and mess to me. But it sounds like you have really found the solution to this particular problem.
Wanted to ask you how you were getting on with your Prusa i3 mk 3 by now? I read some threads going back years where you were comparing options and then decided to purchase that one.
I think your thought process is a lot like mine (not just in this, but also other comments of yours I have read). I specifically recall you saying how you noticed a pattern in all these review videos where people bought "ready to go out of box" which is really just a kit and then they spend a lot of time dickering with it and then finally end up with something nice. :D I have noticed the same thing!
I know you said you bought Prusa largely because family reasons (ease of use, etc.) but I am thinking now of building my own from scratch, maybe one of big cube designs as they seem more stable, and no matter what it seems that you end up tinkering a lot anyway, doing upgrades over time, etc... So the way I see it, if you are doing to do all that effort anyway, might as well save yourself some money...
That nifty bed release thing though was one of last remaining things left in favor of Prusa for me, but now if @BearWithBeard is saying a simple glass plate can work just as well, then... :thinking_face:

Well, for me, the main value in a 3D printer turned out to be building custom enclosures, because the effort/reward ratio is favorable. However, getting to the point where it's easy to do that takes quite a lot of time, and so I can't say I would recommend it. Also, the fumes and the noise are negatives that don't really get as much consideration as they should. The solutions for that still seem to be all DIY, unless you want to spend a small fortune for something aimed at schools or big business.
I found that a CNC machine is far more useful, because I could make PCB's with it rather than having to wait for delivery from JLPCB or whomever. However, I haven't tried chemical etching, and, maybe all things considered, that would have been a better/easier approach, so I can't strongly recommend a CNC either.
Thee was a time when Ender 3's were considered pretty good bang/buck. Seeing what happened to dzjr though, I do wonder whether the mfg. decided to cash out that reputation by sacrificing quality.
Building your own from scratch? Maybe in the end it's the same amount of effort. I can't say, because I haven't tried it. I can say, though, that I've built and re-built the Prusia enough times now that maybe I may as well have. If you have "the knack," I think building something from scratch using better quality parts (such as high quality linear bearings and not the cheap stuff) could make a lot of sense:
https://www.youtube.com/watch?v=Dx6HojLBsnwThe main advantage of a kit is risk mitigation. If you put it together according to the directions, then it should work, at least nominally. i.e. "No thinking required." Dzjr's case seems more the exception than the rule.
Even so, I wouldn't recommend a 3D printer if you don't have "the knack." And if you have "the knack," then you know you have it.

See, now this surprises me. The whole thing about the Prusa is that it is supposed to be "ready to go / well engineered solution." And IMO you are paying a premium for that.
I think you are confirming my suspicions to build my own.
In fact I came to same conclusion in almost all areas (IT, vehicles, building, etc.) and pretty much do all my own work. I suppose that is what drew me to MySensors as well (and OpenHAB, and GNU/Linux, etc...).
And yes, I have "The Knack" LOL! I got a great kick out of that, and shared it already to my family. My wife calls it "bedtime stories" when I start talking about my projects. :D She mostly humors me though, bless her heart.

The reality is more like this plumber's advice about bronze pipe. "It's great, until something goes wrong. And something always goes wrong":
https://www.youtube.com/watch?v=1slibJ52yocFor example, if the sensor that tracks whether the filament is jammed goes bad, then you have a lot of disassembly and re-assembly ahead of you in order to replace it. You can probably guess how I might know this.

I obviously can't speak for everyone, but I'm happy with the Ender 3 and have no need nor desire for another (filament) printer. The print area is large enough for my needs - custom electronics enclosures, spare parts / repairs, little mechanical tools and gadgets, etc. Print resolution and detail is fine, I generally have no noteworthy quality complaints aside from the occasional stringing (which is easy to remove with a lighter or hot air gun). Maintenance is as minimal as it gets: keep the v-groove wheels, belts and lead screw dust free, clean the glass bed. Talking about the glass plate: I fixate it with two regular metal binder clips to the original print surface. It sits tight in place and it's removable within seconds. I don't use hairspray, glue (I tried once - oh boy, what a mess) or anything else, I just rinse it with warm water and soap after a couple of prints. That's it. Keeping it in a good temperature window seems to be key for proper adhesion. I generally start the print with a bed temperature of 65°C for the first (few) layers and drop it to 50°C afterwards for PLA.
Now this doesn't mean that I want to persuade anyone to buy an Ender 3. I don't know if they are still recommended nowadays or if Creality may have started milking the cow. Honestly, I stopped following the 3D printer communities and news once I got my Ender 3 dialed in and achieved pleasing results. I really don't know which printer one should buy today.
But in the end, I don't think it matters much which printer you get. You can achieve good quality prints with most of them and in a lot of cases you'd have a hard time telling if something has been printed on a budget or high-end printer. It is much more important to learn how to use a (as in any) filament printer. How to use a slicer properly, learning what implications different temperatures, speeds and feed rates have, layer heights, how much infill is needed, which distances can be bridged, how steep overhangs and arches can be, retraction speed and distance, to-z-hop-or-not, finding the optimal extruder and bed temperatures for a specific filament, acceleration and jerk limits, cooling,... Knowing the basics of G-code is also very helpful to understand why a printer is doing something or even modify the print. Actually, it already starts with the design process in a CAD program - choosing a proper wall thickness, keeping the structure of the model in mind, avoiding supports if possible, etc.
No matter how expensive or pre-built and -tuned your printer is, those are things you need to get behind either way. The learning curve with a preconfigured, factory-calibrated printer might be less steep compared to a budget kit, because you are more likely to simply adopt the recommended settings from the manufacturer or other community members.
In this regard: if you're a tinkerer and like some challenges, you may as well build one yourself and have a great time! I'm looking forward to build a custom CNC (>1m² of surface area, for woodworking and occasional soft metal milling) soon - hopefully before the end of the year - rather because I'm interested in the build than having an urgent need for one. :blush:

@TRS-80 A while back Tom Sanlanderer did a video series on how to build a inexpensive clone of a Prusa printer from scratch. That would seem like an easy starting point if you wanted to dIY.

I actually saw that! The wood frame made me cringe! First think I was thinking, have my buddy the metal fabricator cut me something out of some off-cut flat stock he likely has lying around...
But then I thought, well, why stop there... (also having The Knack, I suspect you know where this leads :) )...
So then I start thinking about one of these very stable cube designs out of aluminium T-bar (or whatever it's called) some pics were posted by @mbj further up thread.
In fact all of these "simple, cheap" designs with the hot end just dangling out there at the end of some arm into space just make me shudder! I cannot imagine that staying stable...
But then I hear feedback like from @BearWithBeard along the lines that they are "good enough" for all the sort of similar things I also plan on doing with it, which gives me pause.
And then I start thinking about these combination CNC + 3d printer (+ other?) combination devices, and then I think "well, maybe that is the way to go..." <-- Maybe this is where I am at currently? It's all still in "planning / research" phase, for foreseeable future, anyway.
Thanks for the link though! Perhaps a solution meeting someone else's needs.

You should see this then:
https://www.youtube.com/watch?v=v5WjyyeuzksWith these types of rails, the tolerances can be so tight that if you had rails on both sides they'd likely be binding quite a lot. So, though I agree it seems counterintuitive, there can be an advantage to having the support on just one side.

Linear rails! Yes! Now we are talking!

With these types of rails, the tolerances can be so tight that if you had rails on both sides they'd likely be binding quite a lot. So, though I agree it seems counterintuitive, there can be an advantage to having the support on just one side.
Well, with linear rails, yes... But, it's almost... cheating, compared to what I was talking about! :D
All jokes aside, actual design / engineering considerations, bla bla... Of course you are correct.
Anyway, this looks like the "out of the box, ready to go" solution I thought that the Prusa i3 was, I wonder what these go for? After quick search on Internet, wow, comparable in price but far superior design, IMO. Would need to do more research of course, but very impressed initially. I guess these were not available when you bought your Prusa? :)

@TRS-80 I didn't know it existed back when I made my purchase. Even if I had, I might have erroneously dismissed it for the reason you mentioned because, like I mentioned, it's counterintuitive. Videos like this one demonstrate why it can be better.
Marco Reps has a wicked sense of humor. His videos are both informative and entertaining (if you happen to like his brand of humor, and I certainly do).

I got the IKEA LOTS, and the results seem a little better, but still not stable.Sometimes slightly up, then down again.
if I do the trick with the piece of paper and make sure that the piece of paper is just attached, so making a line of the filament, I have to adjust some wheels again every time.
Unfortunately, the supplier of the printer did not respond, so I have no support for that, unfortunately.
As a last option I will place the nuts, and possibly remove the springs completely from the print bed.
I probably do something very stupid wrong and it turns out to be a menu error somewhere deep in the settings or something.
I now have a raspberryPi with octoprint attached to the printer.

Sorry to hear about your troubles. With my Ender I never have to adjust anything. It worked great out of the box and has continued to do so.
Perhaps you could try moving the whole build plate up to a higher point, where the springs are more compressed? There are also people who replace the springs for stiffer versions. Maybe that could help here.
