this model helped me solve a problem with a BIQU Cryogrip Pro Glacier plate at my A1 (see pics). if anyone reads this and it’s expericing similar first layer problems with this plate while the standard texture PEI runs perfectly, I’m also posting the solution (last picture) to my problem which was adding code lines to the Start Gcode of the printer (editing printer profile) to define a different Z-offset to the SuperTack plate (which is what I select when I’m going to print using the Glacier). For the standard textured PEI, the z-offset was -0.02, and for the Glacier I defined +0.03. The results became perfect after doing this.
