3+1 Axis Milling with rotary attachment

Hello.

I have built a 4 axis machine with Y,X,Z on a gantry bridge, and a rotary attachment on the table.

The rotating vector coincides with the Y axis, or X axis. (I can choose to attribute whatever axis i want to these directions)

 

The problem is that I can't generate proper Fusion360 gcode:

 

I've seen online that you're supposed to select the "Wrap toolpath" Option, but that doesn't help much. In simulation, the machine is rotating, crazily, and not the part.

Because of this, I can't mill a pocket because the tool won't reach it, and I can't mill any holes as well.

 

What procedure can i get for milling holes and small pockets in these cylinders?

I'll only be milling cylinders/tube shapes.

 

As in the picture, if i select the top of the contour, it will mill "ok" (rotating the machine instead of the part, which is not fully "ok")

 

If i select the bottom of the contour, it will not generate gcode because it is not reachable with the tool.

I couldn't tell from the picture alone what you wanted to do, but I have heard that if you want to machine the entire circumference of the cylinder, the method of wrapping the toolpath is not supported.
As a solution, why don't you try rotary pocket machining?

Your rotation has to match the physical machine.

The fact you see the spindle moving not the part is just due to your simulation settings. 

Ensure your g54 is center of rotation.

I required to mill holes in this tube, the problem is that the machine is
rotating around the tube instead of the tube rotating with a vertical Z.

Try changing to machine-based in the view tab of the machine simulation mode.

yes, that is only a simulation thing you have set up. The code will be correct. 

Change it to this and you should be good.
