Angular motion


Its been a long time since Ive had anything to say to the list. I still dont have a machine (well I do its a hurco with a shot control will be planing on making a EMC machine out of it for my friend who just picked it up).  Anyway
this same friend has an interesting spline he is making, he had a machine shop make a master slide so he could manually make these parts he needed done, now what he is wanting is for me to build a +1 and angle axis to attatch to his existing nc machine, no big deal, problem is, it will be 4th axis rotary, Im seeing lots of talk recently about the slow motion of the axis.  My emc machine took a massive dive last month, and I havent taken the time to rebuild it, however I think that this problem may be related to the code involved with the accual axis versus the setup,  I could be wrong, but because this is a huge interest to me, I had better get to cracking.  In the time ive had to work on building the controler units for the steppers we have. Ive been using a win box to tinker with,  and I figure ill install emc over the next few days and see if I cant come up with more questions to ask reguarding this.
     Has anyone tried converting   axis A into a linear axis almost like an extra X and seeing what sort of motion is produced that way?  maybe a way to try going about it for some testing. Im lame and slow. But I try to keep up with the list and think of something decent to say.
