Thanks for sharing this. The recommendation wouldn’t be to wait overnight as it’s a long period and would not help too much. Here is what is our recommendations for solving the problem: Place the Cool Plate face down on the heated bed, with the Engineering side on top. Set the bed temperature to 100C and wait for 5-10 minutes Set the temperature to 30C and wait until the bed cools down to that temperature Remove the plate and inspect it, to see if the bubbles are removed.
