Why is it that if try to start Mach 3 from "run from here", the machine goes way off its coordinates?  I've done it  hundreds of times with different code and it always worked fine.  This is a new project, with new code, and it runs fine if I start from the beginning.  If, on the other hand, I bring the machine home, and then set a point in the code other than the beginning, the machine forgets its coordinates.  Why am I missing?
