Yeah petg you have to add a sacrificial layer of generally hairspray or glue stick to make sure the petg doesn’t bond with the glass

I have several chips in my glass bed from petg

I usually now spray 3-5 layers of hairspray on my glass before printing petg

That’s my fault for jumping in without researching lol.

Now I see why PETG isn’t as popular.

I needed something with more heat resistance than ABS but I didn’t want to go through the work of making an enclosure
