I’ve been using a 1/4" thick sheet of carbon fiber for years now. Once warmed up to temp prints stick hard on it. As soon as it’s cool a breeze can push a print of the bed. Plus it won’t shatter like glass does eventually, boy was that a surprise. You still have to wipe clean with some rubbing alcohol before printing.
Bad bearing on a moving part. Or a bur along a rail, It catches just enough to cause the smooth motion to jitter a bit as the head moves along. Blobbing the material down instead of spreading it nice and even.
You have a draft going through your room, I used to have same issue when my printer was beside a window. Less when I moved the printer to middle of the room and issue was gone when put the printer into a closet. With closed doors.
You can try lowering bed temperature to, the warm bed keeps lower layer pliable but the upper layers cool and contract pulling the more flexible layer up and away. So a cooler bed temp should make the bottom layers more ridgid.
You give the word power and meaning by viewing it certain way. To me cuss words have no power they are meaningless. equivalent to a simple filler word. Others around you might give power to cussing, but then why is it your fucking problem that they choose to be simps for a word?
Everyone worried about the bending force, the retaining slots will tear out and drop the damn thing on the desk well before it bends.
This to shall pass, a grind?
