Balsaman I kinda suspected that would be the option unless I go with two computers and just use one to drive the rotational axis.
anoel you are close. The z axis actually has a floating axis mounted on it with a bottom stop to keep it from going to low. The motor driven z axis will be used to make rapid roughing passes and finally set completely on the pattern for the final pass which is where I need to be able to change speeds on the rotation to make for a very fine finish. I of course will slow the feed speed on the y axis at the same time but I need the ability to change them independently. Another reason is one of the rotational axis is not driven with the same belt system so I can reverse the rotation and cut a left and right hand part at the same time.
