wierd problem

[M.A.N]

Hi everyone
Since yesterday my prints that were going well, started failing from front side and right side of buildplate.
When i paused print i saw that some parts of print didn't attach to buildplate after slice 3 and makes the mess.
I recalibrate the buildplate and changed the film but its still like before.
Any suggestions!?
Thank you

Double check your video settings. Make sure Full RGB in on. Did you have a update to your computer?? This sometimes resets settings.

No. I didn't update anything.
It just happens to those sides of build platform if i load a model there. I should place them about 6mm above sides. So i can't use all of build platform space.

If your focus and measurement of grid is perfect, then you should be able to use the whole plate. I find another thing is the tension of the film against the table. I'm betting the fail is on the left side and back. Also make sure the build platform is flat on the table front to back, side to side. Maybe a screw got loose on the platform and it's lifted up on the back left corner. Just my thinking.

Thanks for your advices
When buildplate is attached mess happens on its front side and right sides in some certain points.
I cleaned all the lenses and glass and quarts.
Its a bit better now. But still in that points base layers from 2nd layer and on they have problem.
But in other places its perfect .
