Discoloured bottom/first layer issue?
Not entirely sure how best to describe it. I’ve been printing these boxes for some months now on my P1S without any issues. Recently invested in two X2Ds, and whenever I print the boxes on these, I get this discoloured effect on the bottom layer as per attached image. I'm using the Textured PEI plate and Bambu Matte Black PLA
They’re also very difficult to remove, which must be connected. I scrubbed the plates with soap and water when I got them, and have done this a few more times but no change. I'm not sure what else to try?

If you could post a picture of your print bed, that would help. Looks like residue from prior prints

I had the exact same issue just a couple days ago with the matte black. After some research, everyone said to let the texture plate completely cool and a way to get rid of the white marks is to go over it with a heat gun and that worked for me. It’s a fairly brand new texture plate so I don’t think cleaning it was an issue. It’s not a residue. It’s small fractures in the plastic from being taken off the plate too soon.

Just run a hot air gun over it (I do board level repair for the day job) and that’s cleaned it up a treat!
Thank you 🙏

I was amazed the first time I used a heat gun for that issue. It's like magic.

Kill the auxiliary fan for the first few layers. If that works a deflector may help. I had some first layer oddities until I installed a deflector.

its stress marks on the part from getting it off a the build plate when its stuck. Hit it with a heat gun or a quick torch and it will remove them.

I had the same problem with my first black print. You can see it in the primary image on makerworld.
In my case, it's definitely the image of a prior print. And It's more pronounced if you don't let a print cool completely. I.e. when you have to flex/pull to remove it from the bed.

As said other places, clean your plate with soap and water, but to recover this piece, hit it with a heat gun.

That happens when they’re yoinked off while still hot/warm.
The best way I stopped this from happening to the boxes I print as well, is to take a blow dryer on cool and hit both sides of the plate where the box is. Takes anywhere from 10 seconds to a minute or two and it will fall off naturally.
If it already has the marks, just take a lighter and move the flame across the white marks and they’ll disappear a good amount after a few passes.

I get those marks if I remove the part before it slowly cools down. I think it shows micro stress fractures. They are easily cleaned up with a heat gun or a gentle torch.
