Actually I thought I had the effect under control and was on the safe side with PETG. That's because my other printers had glass beds, too. I never had any problems with PETG. My experinence is that ASA and some nylon destroy the ceramic glass ( ceranglas (R) ) completely if larger areas are printed at once. Now I know that the TC glass bed also seems vulnerable to PETG. The Esun red did not stick as much I guess. But the Amazon Basics white sticks so good that it ripped off the glass. I did not have to use a tool to remove the part. Just one finger. Crack.. I used 90°C bed temperature. The first layer was close to overextrusion because the z-offset is set tight. I will now check if that might have been a bad batch of glass. And then probably move to pertinax or a carbon plate as I did earlier when I moved away from the black ceramic glass.
