Beyond changing bits you have several options to try:
1. Select Bold or Normal.
2. Tell the machine to use the 60 degree bit but insert the 90 degree bit (makes wider cuts).
3. Tell the machine to use the 90 degree bit but insert the 60 degree bit (makes narrower cuts).
4. Place something (shim) on the board where it touches the board to establish depth so it carves shallower.
5. A combination of some of the above.
