I am sure that the description is very clear to you, but I can't yet work out if the spindles turn in the same direction, or if the tools for each spindle operate on the same or opposite sides of the work. It seems like you should just be able to change coordinate systems and use negative Z values. If you want Z to be positive away from either chuck, depending on a mode change, then how do you allow for the fact that the Z-axis position is out by a couple of feet when you switch modes? What do you want to happen when you do switch modes? If Z = 10 is 10mm from one spindle and you change mode, do you want the tool to instantly shoot to within 10mm of the other spindle? How do you want to inform the system which spindle you are working with? -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
