ABS sticks to aggressively to build tak--I think the problem is that it's a flexible surface so ABS doesn't pop-off when it shrinks like it does on harder surfaces. I removed it which isn't easy, it took about a cup of acetone and a half hour of scraping to get all the glue the factory installed build tak left on the plate. I'm now using a glass plate with kapton tape and my abs prints remove themselves when they cool.
