Hi! I got my X1C in february (with a warped bed), but I got 2 friends which are very interested in the printer - except for the warped beds of course. So they are still waiting with their order, thinking about which printer to buy.
Could somebody who got a new X1C in april tell if the beds which are delivered now for new devices are still warped? Or are they okay?
I received my printer early april, ordered it early march. My print bed is not perfect but acceptable for me when I printed a large print that took up 3 quadrants of the bed and lays flat. Regardless no idea what the data looks like and the main thing you want confidence in is ability to return / exchange as needed
If you are lucky, it will be good. If not, not.
I just got the replacementās for my X1Cās today. Both are heavily warped.
My advice, if you donāt need a printer right now - donāt order and wait. If you need a printer right now, go for another brand.
Got my 2nd X1C late last week and the bed and everything else was perfect like the first one.
I got mine in mid march and it has a warped bed that Bambu says is within tolerance.
Same here, got my printer beginning of April with a quite warped bed. After 6 emails (within 10 days) support told me, it is in tolerance use brim.
Nice support, btw.
Anyhow, hole printer goes back because of ringing and different other issues. Unfortunatelyā¦!
I dont think this is really a big issue. I got mine the first week of april and its flat.
Just like any product, you will see complaints/issues more because people with no issues donāt often make posts saying everything is working fine
Iām hoping you are right. After being on this forum for a few weeks, I figured I was just lucky to get one with no problems. But then I got my second one last week with no problems as well and Iām betting that a very high majority of the printers donāt have any issues. This is not a really good forum for people who are deciding to get their first one. I mean, you can learn an awful lot from the people here, but there are so many naysayers, and doom and gloomers, that it will make first time buyers very skittish.
I got mine the first week of April. The bed has a 0.5mm valley running fore and aft.
A little disappointed. But I will keep printing on it until it becomes a problem.
The latest X1C I received in April, arrived with less warp than some of my better P1P beds - I donāt think this is any indication of quality between the higher priced machine and the entry level offering - rather itās just hit or miss from the factory. And with this style of bed, Iād not expect it to be perfectly flat ā as thatās been the messaging from Bambu Lab. That said the BambuLab firmware ABL does a good job of compensating for minor bed imperfections and makes a good first layer, provided your bed is within their spec (whatever that is). But if you actually need flat parts for engineering work (as opposed to warped parts with a great looking ABL compensated first layer), then youāll need to do something to actually physically correct the OE bed. Hereās two prints side by side of my latest April delivered X1C with a properly trammed OE bed, featuring all the hills and valleys it was delivered with - ABL turned off to expose the problem areas. You can clearly see that the print on the left, with no physical bed correction, has disconnected extrusions where the bed dips and scuffing where the bed is high. The print on the right was done on the same machine, again ABL disabled, but this time with physical (not software) corrective measures applied. The corrected bed prints great first layers and more importantly - flat parts.
Got one in the beginning of April and second one just 2 days ago. None of them have warped bed. Ordered in EU shop.
May i ask u what kind of physical adjustment u did? Did u put some tape or similar under the print sheet?
@lasermonkey and @Cangoou, what level of warpage is being considered problematic? Are people finishing prints and seeing a part that teeters on a flat surface? Or are we talking about a few hundreds off at various points on the bed.
BTW, mine is from Feb 23 and I donāt see any issues.
I started down the road of adding tape, but wanted a more permanent solution, that I could share between machines. After all, not every print requires such a precision surface. And if it worked out, I figured Iād eventually make one for all the Bambu printers on the rack. Anyways, what I did was make up a corrective plate from cast aluminum tool plate, lightened and surfaced to within .002-inches across the distance of the plate. The plate is embedded with magnets and a ferrous material so that it stays put on the original bed and likewise holds a build plate. So far its working out well for more critical prints.
I donāt know what the threshold is according to Bambu - they have never stated it. My worst bed was on a P1P that was 0.6mm out (cratered in the center of the bed). It gave me real fits not just with large parts that needed to remain flat, but with prints containing multiple items as the warpage was severe enough that the ABL couldnāt account for about a 20 mm band around the perimeter of the plate. Bambu Lab support took care of that machine without issue. My other machines all seem to be within a range of 0.15-0.35 mm. With dips occurring in various places. The firmware ABL seems to be able to adjust the first layer to adhere well on the less severely warped beds, but regardless of the first layer, large parts will in fact take on the shape of the bed - and will rock on a flat surface. I think everyone has their own ātoleranceā - the printers ABL masks the error quite well, and if all one prints are Baby Groots and Articulated Dragons, wellā¦ then you can get by with a pretty badly out of spec bed and be perfectly happy. At the asking price, these machines really are quite amazing, warped bed or not.
Agreed. I also have 2 printers, one received in Feb and one received in April, both have very flat beds. I have no doubt that there are some beds that have issues, but I think the majority of them are good and the auto bed leveling does a good job of compensating for it.
Totally. Itās sampling bias issue, particularly in the thread about the warped beds.
Not to mention youāve got people taking measurements with random objects, childrenās rulers (which probably arenāt straight to begin with), and using bright ass flashlights to try and see gaps on cold beds.
In all honesty, I donāt expect them to be flat. The bed could be perfect, but the adhesive and magnetic surface will almost always be out. I would assume itās pretty tough to get better than .010āā or .25mm without out charging a fortune. That said, Iāve pulled a couple of flat unwarped prints and they were virtually flat. Didnāt have a feeler gauge small enough to fit in between it and a straight edge. Iām pretty sure if I look hard enough, I can find an area, but itās pretty solid for my use. For reference, I print only functional stuff, wellā¦ as functional as plastic can be.
Also note, every print will take the shape of the bed, but larger prints will take that shape and potentially warp due to the temperature differential from top to bottom. As the temps on the bottom stay at the bed temp and the temps in the middle cool down. The cooling will cause a contraction and warp things, basically ripping the bottom off the bed.
Sorry if Iām preaching to the choir, just disregard if you know how it works.
Thanks for all your replies and opinions!
I read some of the discussions in the ābig threadā and I understand that there might be a bias in the perception on how many beds are affected. And that people have different requirements resulting in different perception when a bed is considered as ātoo warpedā.
As a newbie in 3d-printing, I was a bit suprised that the flatness of the bed might be a potential problem. I tried to read a lot before and after starting and got a lot of articles considering clogged nozzels, moist filament, you-name-it, but I didnāt stumple upon this topic at all.
What is ātoo warpedā for me? Altough some ideas of using the printer to create commercial objects are floating in my head, Iām so far using the printer as a hobby, so for me a warp that is visible, that makes things wobbling on the table or 2 parts not fit together is problematic. Not sure whats that in mm 
I asked BambuLab for more info
I asked if the new ordered Printers are with the new printbed or with the old warped one and how can I be sure to receive the new one if I make order
They answered: No, we ship all randomly and they can not say if I receive good one or warped be.
On my question: How to pay 1700 Euro for printer with defect !?
The answer is: We have support ā¦
Since not all of the old beds are warped and some of the new beds are warped, this seems like a perfectly acceptable answer to me. If Bambu Lab knew which beds were warped, they probably wouldnāt have shipped them out to begin with.
