Router was on #3
My depth was .1
I used a 1/8" straight 2 flute from inventables for the roughing (100ipm/100ipm/.1 depth)
For the detail pass I used a 60° 1/2" bit from Whiteside. (100ipm/100ipm/.1 depth)
It took 5-1/2 hrs to run the detail pass it estimated it at 1 hr 52 min, the roughing pass said 17 minutes it took just at 25 minutes to run.
This was the first time I ran an entire project as one pass, normally I run my my roughing in two passes detail in one pass. I set the depth of cut to .08 so it runs over the larger areas twice to clean it up. Lately on my detail passes on PVC I have been running it at .1 single pass.
I typically use .1 as my depth seems to work out good for my projects, unless a border or font can take more. I have found editing the depth in those areas can save a lot of time this way the tip of the v-bit isn’t trying to open up areas the roughing pass doesn’t get.
I have had areas chip out as well on pine and MDF, on the MDF I push the router speed up a little and it seems to help.
hope this helps! Steve
