A few beginner questions reg 4th axis function

Hi guys.

1. The 25mm 3.175 1/8 does the job well on the 4th axis but of course the surface is left unfinished. I tried to use the flute 30 degrees but what I see T least is that the bit does not even touch the surface of the wood. The step down is deactivated and nothing.

I was thinking maybe use somehow the 3.175 roughing to finish also? Have any idea how I decrease the step between runs to make the surface even smoother?

2. The flute 39 degrees 0.2 mentioned above, when used after roughing, touches with the upper edge the unlect cut wood and I almost lost the bit. I did add supports to the left and right of the wood part. That's the critical issue with the finishing paths.

3. Is there an option to leave the lateral supporta unfinished and finish just the main part ?

4. When changing the bits, I saw the machine does not make the button probe check again. Maybe that's why the 0.2 does not touch the surface when finishing the wood part? I did uncheck the origin check for the finishing stage.

Thank you.
