Read this one for the bed type
Also they did have to replace the AC board all was handled under warranty for me by the local distributor
Iād just like to say this ultimately solved my problem with warped bed. Thanks for the links. I like my printer again.

Are there any US based vendors making a bed comparable to the KiS-3d unit?

I couldnāt read all 1500+ responses in this thread.
Has anyone simply taken their print plate to a machine shop to have it resurfaced?
Thatās a pretty simple task for them, they should be able to use the same machines, milling or other, used to resurface engine blocks. And that should be under a $100 shouldnāt take more than 20 minutes.
The advantages I see:
Cheep, fast, surface plane to a 0.01mm.
Bed just needs a new magnetic sticker.
Bambuās warped bed problem pretty much went away on machines produced after May, 2023.
Bambu will replace warped beds under warranty, at no cost to you except your time to install the new bed.
Re-surfacing does require removal of the magnet surface. At the time when warped beds were common, that part was not available separately. Even now, it is a $20 part. So, $100 to a machine shop and $20 to Bambu (plus shipping) and you are at the $120 cost of the entire bed assembly.
My original bed was off by 0.8 mm, the replacement bed is off by 0.07 mm. The deviation does not affect my prints. Generally, FDM printing is only accurate to about 0.5 mm anyway, so there is no point in chasing additional hundredths of millimeters.

Hi Ikraus,
I bought my X1 in octobre 23 and my V3 bed is warped.
Iāll see if Bambu changes my bed.
I did reached out to a local shop and they would take $60 for the leveling.
So it isnāt a bad option if needed.
Thanks.
Thereās nothing to machine. The bed is an assembly of injection molded plastic, a very thin heater panel, and the magnetic sticker.
Oh ā ā ā ā , thatās a bummer. I was under the impression it was an aluminum part.
Thanks.
Iād be pissed if I paid $1000 for a printer with an uneven bed like yours.
I got lucky. My P1S Combo has better than Ā± 0.012mm @ 55Ā°C, 70Ā°C, 90Ā°C for all 36 automatic bed levelling points. With a simple tramming of the back of the print bed will get it to Ā± 0.080mm.
Yeah, donāt buy an X1 if you want flat. I was printing wheels on my A1 and they would wobble badly on the shaft. I have an old glass bed on an Ender 3 and it makes perfectly flat wheels. Not only is the glass flat but on the Ender 3 you can even adjust the 4 knobs under the bed to get it very level, too!
If itās a 1 year warranty, then Iām outside the warranty window. Kudos to you for getting the jump on it. I would have noticed something amiss right away if I had tried printing a single layer āperfect first layer.ā For any future printers, Iāll be doing that print the day I unbox it. At the time, I didnāt know to do that.
Printing the first layer at 0.3mm layer height seems to help compensate though. Easy to set in the slicer. Subsequent layers can still be 0.2mm layer height. The 0.3mm first layer height can cause issues with some models, though, as Iām now discovering. Better to have the flat bed 
and then youāre golden.
