seems to be a hit or miss, sometimes its fine (not perfect but fine) and sometimes its horrible 
Maybe more hits than misses? The number of new reports of banana beds (in this thread at least) is very low.
Iāve been super busy with work but one of my projects is to try and find a cheap viable solution that #1 works #2 doesnāt look janky and #3 is cost effective
Although I have no issues with my bed Iām still wanting to help those in need
I purchased some magnetic film with a very strong adhesive and a film that attracts magnets again with a very strong adhesive
Iāve got a 3/16 thick tempered glass plate that will be here Tuesday
As a test mule I used one of my cheap printers and using the magnetic film and magnetically attracted ferous films have successfully secured a glass build plate to the bed with no clips
Itās actually somewhat difficult to remove the glass build plate due to the strength of the 2 films magnetically attached
With my X1C Iāll leave the original magnetic film to the bed and put one of each film to the opposite sides of the glass thatās on route
Once the glass is secured to the bed magnetically the regular flexible build plate should stick to the top of the glass just like it does in its factory form
If this works as expected the next thing Iāll be doing is designing corner stops for the flexible build plates in Fusion 360
On an unrelated side note Iām also working on a dual auxiliary cooling fan setup in Fusion where the fans are at the bottom of the chamber with the ducting running up each side
Although it will lose about 3 inches of build volume in the Z axis the benefit will be auxiliary cooling on both sides
But thatās for another day
For now hereās some pics of the build plate project progress, itās easy, cheap, and not permanent
Telling people āHonestly no one has received a reasonably straight bedā while at the same time Bambu Lab let you return your printer way after the return window closed and provided you with a printer that, by your own admission has a responsibly straight bed is the issue. You had a flat bed and were still telling people that āno oneā had received one. Thatās actual deception.
Iām not making claims about how many beds are bad compared to how many are good. I just know, based on this thread and others, that the majority of the beds are fine Some are bad and need to be replaced.
Finally got my first warped bed yesterday, with another arriving Monday. Will begin scanning these next week.
I know you run PR for Bambu and bending over hard for a scrap or two, but you canāt cherry pick my words. What was my next sentence? āIt could be better, it could be worseā. I am frustrated with Bambu and you keep on quoting the first part, without saying the rest.
Here is my data point: I have dealt with four beds since start of April (two were replacements) and the other two were X1C combos. Out of the four only one had dips less than 0.10mm. I am sure your experience differs, but I am not going to try to convince people to buy these printers as it isnāt as small a problem as we like to think. Unless your main use case is etsy tier soap dishes and NASA logos.
Secondly donāt make it seem like they did me some huge favor by āletting meā return a defective product 
For the record, the good one I did get is a joy. And I donāt think ā0.10mmā is still āreasonably flatā for a $1500 printer but just enough to live with

Itās been a while since Iāve posted an update on my warped bed adventure, but the quick version is that as of today I now have a workable solution. I, too, received a warped replacement bed. Not nearly as warped as my original, but warped enough that Iām not going to bother installing it. Iāll keep it as a backup.
I purchased a 10in x 10in x 1/8in sheet of borosilicate glass to use as a new build plate. Yes, itās a little small (254mm x 254mm), but Iām willing to give up a little length and width at this point. Iāve seen that others are using the same kind of glass and permanently attaching it to the heatbed using silicone, which I thought about doing, but I really like being able to print on glass and then put the plate in the freezer for easy parts removal and cleanup. So, I heavily modified these low-profile clamps, adjusting the heights as well as how far the tops extend over the plate to ensure a snug fit on all four sides despite the evident warping of the plastic frame around the heatbed. I also had to modify the startup G-code to account for the smaller build area.
I then printed two long āsticksā that are tall enough to resist bending once cool, in order to make sure that both prints are actually flat and the bottoms can be placed flush with one another naturally (not just because I press them together). First layer was looking good!
And here is the end result:
There is a little lift-up at the very ends, but that is because I forgot to put sufficient glue in those areas. Results are nice enough for my needs until such time, if ever, the community gets a better bed from BL or a third party that cares more about accuracy and quality than BL seems to. Right now the clamps are printed in PLA, which is not great, but I have some ABS ordered and will reprint them next weekend.
Is it ideal for me to have to fiddle with clamps every time I take the plate on or off? No, but I am also willing to put up with some inconvenience in the print setup to have the big convenience of borosilicate for flatness, rigidity, heat retention, and parts removal. And I bought two plates, so while one is sitting in my freezer, I can load up the other one and keep printing.
I am still furious with BL for selling me a printer that I was only able to use a few times before it had to sit idle for four months while I sparred with their tech support people, experimented with multiple DIY solutions, waited anxiously for a replacement bed (only be disappointedā¦againā¦by what they sent), and then ultimately fixed the problem myself. I suspect that one of the (many) reasons why BL wonāt admit fault is that they have a smart lawyer telling them not to. Otherwise, they could end up in a class action lawsuit. They still might, but by not admitting fault, itās up to the impacted consumer class to prove that the issue is real. Regardless, this is likely my first and last BL purchase, now that Creality (and soon others) are offering the same capabilities at lower price points with better manufacturing and quality assurance track records.

If youāre going to go there, then you must tell us how much Josef PrÅÆÅ”a has been paying you to continuously troll this thread like itās your job

I used to do this too when printing on glass ā and itās a lot of extra work. But, it works extremely well every time.
Thanks for sharing those clamps! These clamps work well too. And the bed is perfectly secure when just clamping the front corners of the glass.
Aqua Net hair spray works well when printing on glass (thatās what I use). If you let the bed cool down to room temperature before removing the parts, the hair spray usually doesnāt need to be reapplied until after 10 or so prints. Before doing so, make sure you clean the glass with soap and water.
Indeed, it does. My personal preference is to not have to deal with spraying anything, but I know a lot of folks swear by hair spray. Iām just glad that we have a few affordable options for keeping parts secured to the bed during long prints.

Me too. But, like the freezer idea, hair spray works so well that itās worth the inconvenience (been using it for 5 or so years). If you spray it over a sink, itās easy to clean up afterwards.
Manā¦ call me weird but inhaling that Aqua Net is something I canāt make peace with haha. Thatās why I default to vision miner
I know, I know we have different risk tolerances and all. All in all, Aqua is a great solution
I also recently tried layerneer which is excellent
Haha, well, you gotta hold your breath while spraying I guess 
Oh of course imagine sniffing in Aqua Net HAHA
Take note of my post earlier on this thread using magnetic sheets and ferous sheets that attract magnets
No need for those clamps
Simply apply a magnetic sheet to one side of the glass and a ferous sheet to the other
Your glass will not move I promise you and with the magnetic sheet on top you should still be able to use all of the available flex plates just as you were previously before the glass was added 
If I ran PR for Bambu I wouldnāt be admitting that some beds are bad. I wouldnāt be working on a flat bed solution for others. Iāve said multiple times I know some people have bad beds and itās a problem that Bambu Lab needs to fix.
My experience does differ. I have two X1C combos, both with beds +/- .05mm flatness. However, Iām not saying my experience is universal and that 100% of Bambu Labs beds are flat. I have no doubt that a small to medium amount of beds have some unacceptable amount of warp and need to be replaced. Certainly not a majority.
Even though your experience differs from mine, It seems like Bambu Lab is still trying to work with you and make things right. And thatās good news for all of us for when things eventually go wrong on one of our printers.
And you shouldnāt try to convince people to buy them, if you had a bad experience. I donāt doubt you had a bad experience. I would be fine with you sharing that you had a bad experience. Again, the issue has been when you misrepresent things to purposefully make Bambu Lab look bad. Youāve even said you were going to spend money on social media to purposefully damage them, so you know you do it.
And honestly, itās fine if you want to do it, but Iām still to offer a counterpoint when you do it. People reading this thread can decide for themselves.
I take issue with it not because Iām a simp or a Bambu Lab employee or trying to get some free stuff (or whatever other thing youāre going to accuse me of), but because I have a vested interest in seeing Bambu Lab succeed. I own two of their printers, I want them to succeed and to continue to develop good products so I can buy more. They should be able to focus on on fixing genuine complaints, not hyperbole exaggerations.
You are the one that originally said they wouldnāt let you return it and you were going to have to do a chargeback. So I just wanted to get a clarification for clarity. Iām glad to hear it was returnable and that you got one with a flat bed as a replacement. I only mentioned being outside of the return window because it shows they are trying to make things right with customers. Seems like quite a few people have been able to get refunds/replacements for warped beds outside of the original refund window, which is a good sign for all customers who end up with warped beds on new printers.
Finally. Thatās awesome. Iām genuinely stoked that you have one that you can print on and glad you stuck it out. Welcome to the club.

Does Bambu pay you by the word count? I canāt read all that
Olive branch. Tell you what, are you based around CA? I am in MN but often in CA, letās go get some steak.
It doesnāt matter if itās two or four, itās time I shouldnāt have to spend doing this. This is not an open source printer/Ender where you are on your own. The fact that (I know not enforceable in USA) there are void stickers on the screws needing removal to do this, tells me they should be doing it.
I noticed more and more companies taking this approach, recently had a Polk speaker fail, and they sent parts rather than offer warranty service up front. However, they still do have authorized service centers where you could mail or take in a product and have a tech replace it.
Bambu should start building out some depots because not ever consumer is comfortable with a major repairā¦
Gāday,
Wish this didnāt have to be my first post here. Iām a fairly new P1P owner, reasonably happy with the printer, except for some firmware bugs that need ironing out. I have only printed a relatively small number of large models where Iāve noticed the corners lifting up, or an imperfect first layer off to one side.I put these down to that the print surface mustnāt have been clean. Then I stumbled upon this post the other day and thought Iād check my print bed. Sure enough, itās got a fairly substantial dip in the middle. I know that light can penetrate through very small openings and that may be showing it to be worse that it is. Iāll put a feeler gauge across it tonight, I estimate it has at least a 0.5mm dip. I guess most owners wouldnāt even run into the situation where it causes failures, as the mesh bed levelling seems to work quite well. Iāve submitted a support ticket last night and it wanted to download my logs. After 15 minutes it had only completed 5Mb of ~360, so Iāll do it by uploading to the SD instead (I had another print to do overnight). Iām hoping the company can resolve this. I do lots of functional prints and would kind of like the bed to be flat.
Iāve had the X1C for a week. Bought from EU warehouse. I checked the bed and at 30Ā°C there is a depression in the middle ~0.05 mm, at 80Ā°C ~0.2 mm, at 100Ā°C ~0.25 mm.

Why do u measure the magnet sticker? Do u print on it?.. i dont think so. You should measure with a print plate on it. Small dents are evened out
