Vcarve Toolpath Issues

Hello all

I am trying to run a vcarve toolpath on plywood and it is coming out very rough. I have it set to a flat bottom depth of .04 and have tried just a 60 degree vbit as well as using the clerance tool option, Vcarve Pro Software, but had to use a 1/16 bit as the text was pretty small. Even with that it didn't come out very clean.

The router/bit is set to run at 18k rpm and 100 in/min feed

Any thoughts on what could be happening?

I ran it on mdf and it looked great

 

Birch plywood

trying to use the v bit because the letters are too small for an end mill.

 

No because I want the flat depth look for this particular project.

 

If it were moisture would I see the same result using an end mill?
