Is it normal process?

Hi all
I have Troubles with model adhering to build platform and I found the same issue in this forum.

But I think it is differnce from those issue.

I could print first time, but from next time, I failed to print because the model didn’t adhere to build platform.

I tried 0.025mm, 0.05mm,0.1mm, and both resin, spare resin tank and build platform but I failed.

I doubt that resin tank always tilt to the build platform within 0.5mm(attached the photo). Is it normal?

Could you advice it.
