Fish,
Post some pictures! How big are these letters?
in case you break any. Sending a compression in 2 passes (halfway) seems silly to me. The upcut part would
pull up the top grain and the downcut really doesnt have any cutting action to smooth the top edges.
Least thats what happened a long time ago for me. Just ramp it in one pass. Your middle part should be smooth.
Sometimes you can get a rogue grain band. Clean the bits after a few uses helps out also.
What machine are you using?
@4DThinker recently had a post on Optimizing CNC job for speed - A good read and he's using a 3/16" comp
as well as I do. 1 pass.
@difalkner has the video doing top speed on his machine cutting the BB Longworth chucks. Love how he reacts to it.

Have you tried going 1 pass? 1/4" will cut 1/2" (12mm) no problem. Give it a try. Have extras on hand
