Wimpy Stars is it my math?

I am having a terrible problem getting my 5 point stars to carve properly, they end up looking like something out of Sponge Bob Square Pants. Not able to get them carved straight across from left to right, tip to tip. They look like they have their arms up and are skinny.

Have tried Vcarve and Advanced Vcarve both 60 deg and 90 deg bits. Bits are 1/2" in diameter and I am testing out on 1/2" MDF.

Base settings:
cuts per pass: 0.1
Have used stock bottom for depth and almost every increment from 1/2" to 6" without any change in results.
Star sizes 1/2", 3/4" and 1"

I have watched this over and over and over. My results end up like his worst star in the upper left corner of his board. Doesn’t matter what depths I use I get the same results.

I will try to get screen shots.

How are you setting zero relative to the stock?

Setting z right down on the board. Paper method.

NOTE: The line cuts were 6mm and cut to depth.
Is this problem with the stars a plunge rate and feed problem???

Does that match the 3D preview in Carbide Create?

If you wish to cut s shallowly, use an Advanced V carve toolpath instead?

Or, use a less acute tool and allow the toolpath to cut as deeply as is needed.
