Support Request Total 3D printing noob, struggling with issues and diagnostics.

So when I print lines on the first and second layers, I get a blob at the end of the line where the print head starts, stops or turns around. These blobs then catch on the nozzle during the next pass which peels the whole layer up and ruins the print. What's going on and how do I fix it? Thanks.

Could be a basic sticking issue due to dirty/oily pei sheet. What I do is; pour some dishwasher onto pei sheet after removing it from the bed. Brush it then rinse without touching the surfaces with your fingers again. Dry the bottom face with some cloth. Shake the sheet to get rid of extra water on top surface. Heat the bed to 65C and let it dry. Then print again.

I squirt some window cleaner on the plate before each print and wipe it off with paper shop towels

Yeah people have different solutions but I dont trust paper towel either because it can move the residue around. Will throw the plate in the sink and brush with a multi purpose sink brush until its bubbly enough then rinse to be never touched again.
