My original PEI Prusa flat film is 2.5 years old and it really looks its age. If I clean it really well I might get a print or two before the adhesion issue becomes an issue again. So I ordered a new powder coated sheet from Prusa. It will arrive in a few weeks as I also ordered a previously ordered part. OK. In the meantime I've decided to order this sheet with less frustration to print. I received the sheet a few days ago and unfortunately the corner was creased. I'm not sure if this happened upon delivery (I'm inclined to think it wasn't), but who knows. The replacement arrived today. First I tried adjusting the thickness of the first layer (from calibration), got what I thought was close. I then started printing with large, flat first layers (although it wouldn't make much of a difference if some of the first layers were slightly offset) and used Live Z Adjust to dial it in and finish the set. FAR (I'm 10% from my first print on the bed but the first layer looks great - after adjusting the height) I'm very happy my print is sticking and I expect it will continue to be . If I'm not satisfied, I come back here and update my thoughts.
