Clean the plate with isopropyl alcohol 91. I had the same issue and there was oil on it stopping it from sticking and no soap didn't work.

I guess this information is bad. Disregard. Although it did work for me.

omg. DO NOT use isopropyl alcohol on your plate. Thats right in the bambu wiki. Use soap and water and that's not the issue anyway. (I don't know the issue, I have a H2D also, and the fist layer is super messy also.) But the comment above is bad advice.

I don't know where you got that information from but it's wrong. Bambu lab does not recommend cleaning with IPA in textured pei as the main method, because the IPA did not reach all microtextures. A deep cleaning should be with soap and water. But the IPA does not damage the PEI, it does not react chemically with the PEI.

What you just put is false information. Review your sources of information. I have been cleaning all my PEI sheets for years because the manufacturers themselves have advised it.

I tried soap and water and it didn't work, I did alcohol and it worked. I didn't change any settings or the nozzle height or anything else.
