First layer calibration strips.

Slice with whatever slicer you prefer, and tackle any material challenges head-on. I fine-tune the live Z during printing to guarantee a seamless start and finish, along with excellent adhesion to the bed, and precise material fusing. As I begin printing, I gradually lower the bed by small increments and closely monitor the prints. I take note of the initial strip's height and make adjustments for each subsequent strip, tracking my progress. One by one, I remove the printed strips from the bed and assess how easily they separate. When I reach the strip that boasts a flawless start and finish with excellent fusing and effortless removal, I've hit the optimal height setting.
