Hi @Aero3D,
Maybe worth a try though, with a good quality 30° Vbit ?
What stock thickness are we talking about ?
Here’s an example of using a 60° Vbit on two-layer HDPE, not quite relevant because it was with much larger letters, but there is no reason why it could not work using small letters and a 30° vbit.
About the neat toolpaths: can you post an example of a design file with toolpaths that are not as you would like them to be ? Sometimes the way you select different parts of the text to create toolpaths has a lot of impact on the resulting toolpath. Beyond a certain point, if you do a lot of vcarving you may want to look at other specialized software like Vectric VCarve, which tends to generate more optimized v-carving toolpaths (but it comes at a cost)
