Makes sense. Being a total newbie to 3D printers I am constantly wondering about optimization. With that comes the possibility of over thinking it.

I think I am going to stick with the Kapton between the heat plate and aluminum plate.

Have you played with PEI on an aluminum build plate? I keep hearing conflicting reports on what the best method on adhering PEI to aluminum. I am leaning toward Silicone transfer pads, but 3M tape is second. Any pros/cons you could share?
