I recently bought a TAZ 6, owned a Mini for more than one and a half year.
On my first build after the rocktopus (so my first “real” print) The build plate got white in large areas with air bubbles and pockets. It was visible already when printing the first layer (so before any part had been removed). Once cooled down you can feel a slight bulge on a couple of the larger bubbles, but I assume the other “airy” areas will become a problem as well.
What is the recommended thing to do? Should I remove PEI sheet and reglue or something? On my mini I haven’t got any bubbling or airpockets to speak of during 20+ months.
