Switch to a PEI Print Surface

My LokBuild was trashed by my faulty sensor. I guess it's time to try PEI I'm not thrilled with how thick this is for the sensor. I'm going to look into an 8mm sensor for this. Or maybe a capacitive one if those can directly detect the PEI. The glossy finish on the bottom of parts is a cool novelty. I'm sure that will wear off about the same time the micro scratches dull the surface away. Chapters
