Man, after spending much time getting to the point of having some beautiful prints coming off I am starting to notice that my first layer goes from thin to thick. I thought my leveling was off (I do not use any auto-leveling system) and spent time and tears trying to get everything to work.
I noticed yesterday that I saw what looks like my PEI sheets (both printers) are bubbling from underneath.
I assume that this is from the 3M product not sticking because of the heated beds. Am I correct in assuming this? And what can I do about it?
I bought this product from US companies and all had the 3M logo.
I very much like the PEI and have had no issue with that particular product as long as I clean it with alcohol and I never had to worry about the slurry, glue, hairspray, etc.
Many thanks again for your help and God Bless.
