Hi All
A quick troubleshooting assistance needed please. My last couple of prints seem to be lifting off the bed. Settings have not been changed so would appreciate any input you all might have?
Thank you,

is it PETG? may be needed printer slower because it has no enclosure.
What material is it that you’re printing?
You are also using the textured bed - iirc they are sensitive to oil and contamination. If you’ve touched the plate directly I’d recommend washing it. I clean mine by wiping it down with a microfiber cloth and 99% alcohol. Many people also just use warm water and a little dish soap.

Spray build plate with Windex and wipe clean.
No aux fan.
Minimum or no part fan.
My heat bed runs cooler near the perimeter by about 7 degrees.
Crank up the build plate heat to about 80c and run it again.
Print first layer at 100 and second plus at 150.
This works for PETG on tex plate.

Hi everyone! Thank you all for your input and advice. I have the bed a good wash and wipe down. Prints seem to be coming out much better!
Thanks again!!
This is the way.
IPA alone can spread around oils rather than remove them if you are not careful, and BL does not recommend its use on their plates - dish soap and water only is a safe way to go and fixes a lot of these issues.

Clean your plate with what works for you. I would be happy if BL or any user publish some data to support statements made in this forum or Blog.
From Bambu Labs blog: "We strongly recommend using warm water and detergent for cleaning our print surfaces, as this works very well in cleaning any contaminants from the surface. In some cases, IPA cannot properly degrease the print surface and instead of cleaning it, oils or grease can be spread on the entire plate causing further issues.
For starters: there are three chemical types of detergent, not including blends of the three types. So which detergent (Tide, Joy, Cascade)? While Isopropal Alcohol is defined and many users use it with no problems, using IPA is a specific cleaning method or at least a part of one.
Then writing "in some cases IPA cannot… remove oils. Which cases? If they have this data why aren’t they publishing it? I’m all for benefiting from original work, but I just don’t see any data here.
And lastly BL maintenance calls out IPA for cleaning!
The X-axis Carbon Rods can be cleaned with isopropyl alcohol and a dust-free cloth. Spray a bit of isopropyl alcohol on the fabric and gently rub the carbon rods to clean any debris.
The contamination that reaches the bed will migrates to the rods and the rest of the printer too.
I think the big deal with IPA is that it’ll dissolve oils, but it won’t remove them. So, one has to have a cloth that will absorb the oil-laden IPA while it is still in liquid form.
Detergent is a surfactant, not a solvent, as well as a cleaning agent and will actually bind oils, lifting them from the surface, allowing water to carry both away with a rinse.
I’m unsure how awesome a combination of the two might be? Time for another experiment? I still have my IPA vs Detergent experiment running, though.

Excellent, thanks,
Try to determine what detergent residues are present. Years past the electronics industry found they had no way to remove detergent from their boards. When MOS devices were implemented humid weather conditions became new electrical circuits. You may find that repeating the cleaning several times might do the trick of creating buildup.
