using 4th axis or rotory indexer
I have seen some video's of turning a piece so it can be carved around. My question is do you need 4th axis for this. I see it looks like it is using 3. I to turn and Z axis and Y axis. In the video I think X is turned off and used as A axis. So if you only need 3 axis to carve a table leg or cane then what do you use the 4th axis for. I hope this makes sense.
Thank You
