Sovol 310x310mm Flexible Steel Build Plate with PEI Surface & Magnetic Base - Compatible with CR-10, CR-10S, Anet A8+, E12 3D Printers | Perfect for Smooth Printing & Easy Removal

I've been 3D printing for a while now, I get my first layers pretty much perfect on all of my printers. I bought a Sovol SV05 and the stock PEI platform was warped pretty bad (plus the magnetic sheet wasn't that strong) so I picked this up.First, the measurements on the platform are off. The X axis' lines are pretty accurate, but Y axis is off by 10mm (aka there's an extra 10mm of space below the "1" line). Not sure what the idea behind that was or if the machine that printed the measurement marks was off.Second, and more importantly, my prints just won't adhere completely to the platform. I've done PID tuning for the bed, measured the temperature with two different thermometers (one contact, one contactless) to verify the bed's temperature isn't an issue. I've cleaned the platform via recommended methods (91% IPA and twice with slightly diluted acetone once the IPA didn't improve adhesion). The platform is fairly level (a total variance of 0.102mm on a 7x7 probe setup). Unfortunately there's not too much else I can do to improve adhesion except use "helper's" such as a gluestick or purpose-made adhesive (have not done yet, don't want to gunk the platform up anymore unless I absolutely have to).I don't want to give the platform less than three stars, I've read the other reviews, and most are positive, also I do like the design of the platform (the little designated fingerprint tabs, the measurements even though they are off centered) but I am a little disappointed and can't give any more than three stars. I think that's fair for my experience.
