As I've finally bought a functioning CNC mill, I'm now banging my head trying to machine some tool holders for my lathe turret.

Just now all I'd like to do is machine the underside of the holders along with spiralling into the mounting holes a few mm, as that's the critical part. I can then drill the mounting holes, then bore them out on the lathe, however trying to generate the G-code is proving to be a bit challenging.
I've tried CamBam, however waterlining results in the finish pass not finishing the horizontal surfaces and leaving a groove around all the features, and any other method seems to result in lots of air re-cutting.

I'm currently downloading Dolphin to try, however any other options I should be considering that won't require the sale of limbs/organs?

Here's a picture of what CamBam is resulting in -
