I tried to mark 8x8in plastic parts (3-dog handles) with the character string uturnhandles.com along a curve using VCarve Pro but don't get acceptable results.
Text height is 0.20-0.25in, text depth is approx. 0.04-.08in. I tried 60deg V-bits first, then 1/16 and 3/32in straight bits, with several solid line and true font fonts.

V-bit results look better but still not very good, not readable enough and it feels rough to the touch.
I'll try 30deg V-bits next. Probotix Nebula CNC spindle speed 13,000- 16,000, feed approx 60ipm.

Any recommendations? Are Diamond Drag bits better for this kind of small lettering on thermoplastics = soft plastic?
