I assume that you are trying to edge light the acrylic. For best results use a diamond spring bit with the router turned off. You can find them on Amazon for ~$50. I use a 90deg RDZ Engraver from United Stamping LLC…
I should add that I have limited experience with V-bits, however I have created some successful edge lit acrylics with a v-bit. It is hard to make lines with the diamond bit. Looking at what you posted, your depth seems too deep. Mine was only .02" deep, with a 60deg vbit. You may not like the width of the line with that depth and a 30deg vbit. Try something shallower, say .05" and see how that looks. Also, my feed rate was 45ipm and 12000rpm on the router.
I have lots of hard-earned acrylic experience. First and foremost, it should be CAST acrylic if you’re using a bit and router. Extruded has melting issues b/c it is formed at a lower temperature. Cast is (usually) paper-backed; extruded is film-backed. Also, there are good YouTube videos on this topic.
If it’s film backed both sides it’s very tricky to mill (or route). There are specific plastic cutting bits - you want O-flute spiral upcut. The upcut pulls chips out of the kerf to reduce re-welding (melting). Onsrud has these bits as well as feeds/speeds.
