How often should you wash a PEI build plate?
Wash it when prints stop sticking, not on a schedule. Prusa wipes with about 90% IPA and saves soap for a last resort; neither maker allows acetone on textured PEI.

Why did my print warp on only one corner?
One lifted corner has less grip or more cooling than the other three. Five causes to check: bed height, a draft, a cool bed zone, skin oil and a sharp corner.

Why won't TPU come off the build plate?
TPU welds itself to a hot bed, a squashed first layer or bare smooth PEI. Bambu Lab lists 35 to 45 °C on PEI plates. The causes, the fixes and a safe way to peel it.
