V bit 60 not completely carving

Attempting to carve simple sign using v60 bit, sharp. Bit is secure in router, bed and material level. 2" letters, Times New Roman, flat depth 0.4", :Ramp plunge 1.0", Safe Z 0.6, using probe, cutting parameters for 6ov: pass 0.433, final pass step over 0.021 4.2%, clearance step over 0.125 25.0%, Spindle speed 16,000 feed rate 15.0 mm/sec plunge rate 5.0 m/sec
Problem: bit does not completely care letters, raise above cutting area while making all the motions of making the cut. As one of my attempts I made the letters bold with not change in outcome.

Can you add a picture?
