Frame: ic! berlin
Lens: Polycarbonate
Machine: Santenilli Lex 1200

I have already recalibrated everything following the instructions on the manual book.

Decrease size and set groove depth to .8 mm

I would change material to Trivex or high index. A poly grooved to a deeper depth will not look good.
