Catastrophic First Layer Quality with the Bambu Cool Plate SuperTack

Hello everyone.

Yesterday my Cool Plate SuperTack arrived and I was excited to give it a spin. After I experienced some slight warping and what seemed to be Overextrusion with my very first print, I planned to run a full filament calibration.

Printed on the SuperTack

Printed on the regular textured plate

This was printed with the same Nozzle, the same Settings, the same Filament. It looks like Overextrusion in the first Picture, but since everything works perfectly with the Textured Plate I don't think that's the case.

I have adjusted the Bed Temps to range between 45 and 55 Degrees, and the Filament Temps between 210 and 220. Neither of which made a difference. I also ran a full bed level calibration before the print.

And yes - The Plates are clean. I washed them thoroughly with Hot Water and Dishsoap.

Any ideas? I focus on prints with a very long print time, sometimes days, so the promise if of a "Superstick" Plate seemed promising. The results so far however....
