funny but not surprising. its no easy task and alomost impossible to get something that works great with everything. since i am in the coatings business, not long after gecko was introduced i developed a plate that worked great for abs. i just couldnt get it to work with pla. just the opposite problem these guys are having. i was using my plate for awhile but in the end though i went back to my hairspray coated aluminum. it really just doesnt get any easier than that. the real issue is that you have a piece of spring steel and no matter what you do its just not flat enough. a 3d printer requires a flawlessly flat bed that you can really only get with a machined surface. even my mic6 tooling plate is out enough that i can see just by how it prints the 1st layer.
