I keep harpin' on this one, but people just can't seem to come to understand it. MN (Move Nudge) and click the down arrow (for negative or down) on the Z axis, to the desired amount (-0.005 in Scott's example), hit enter, done, re-run the file.
Another option that I use often is to apply a slight offset to the font. Group it and use that for the new toolpath. How much depends on the font and size, but start at 0.008 - 0.01.
If guns kill people, I guess pencils misspell words, cars drive drunk and spoons make people fat.
