K1 MAX Build Plate, Double Sided PEO PEI Bed Sheet, Magnetic Spring Steel Diamond PEO + Textured PEI Surface for Creality Ender 3 V3 Plus, CR-10 Smart/Pro, Ender 3 S1 Plus,310x315mm

Product came in as described. It's been working great.The only thing was wrong size was sent, it took 2 days to get the correct one.

PETG doesn’t stick to the PEO side of the sheet. It’s dried and perfectly calibrated. I flip the bed over to the PEI side and PETG sticks like glue. The description says PETG works on the PEO side but it doesn’t on my build plate.

excellent bed adhesion.

The build plate seems to be pretty well made. It is every so slightly thinner than the 1st party Creality A and B plates. The textured PEI side has a nice texture to it, which is a bit finer than the Creality B Plate. The PEO side looks interesting and I would have liked to have tested it. Unfortunately, it is manufactured with the notches cut in the wrong spots for the K1 Max. Neither notch is in the correct position to line up with the K1 Max's plate stopping bolts. Same goes for the notches cut in the magnetic sheet that came with it. They are in the same location as the plate itself. Due to this error in marketing (or maybe manufacturing?), I am unable to use the product in an efficient way. It's incredibly difficult and frustrating to try to use build plates without being able to fit them against the stopper screws. Nobody wants to finagle things in that way. I would suggest that K1 Max owners find another plate. I'm sure it's a great plate on whatever other printers it actually locks into place with.

My fault. I didn't read the listing well enough. It's right there "Bed sheet dimensions: 310mmx315mm". Oops. They seem very well made and the magnetic sheet provide good adhesion to the sheets. I will use these to hold screws and parts when I am working on various projects so all is not lost!
