I'm routing into one and a half inch mahogany. The strokes on the letters are fairly thick. The finish depth is 3/4" inch. I have already routed two boards and have noticed that you can feel and see the step on the side of the letters. I tried the step down first at 3/16" and then at 1/8"and had the same result. Any suggestions?

If it's mostly on the endgrain, it may be chalked up to bit deflection. You did two cuts with differing step-down settings, but did you do a finishing pass on either of them? I would run a finishing pass that either hits the same final surface or takes off just 0.005" in the conventional cut direction. The step-down on the finishing pass can be almost the full length of the flute of the bit. The slight cut shouldn't deflect.
