Re: [CAD_CAM_EDM_DRO] Y Axis Motion

Hi John.

Assuming that your spindle remains stationary, moving the table away
from you should decrease the Y value. This is because the coordinate
system should be right handed with respect to spindle motion. This
means that (assuming you're in front of the machine) X increases as the
spindle moves right relative to the work (so table moving left with a
stationary spindle), and Y increases as the spindle moves away from you
(or table moves toward you).

And remember, for Z, up is + and down is - :) (this one actually causes
me confusion - it just seems like extending the quill should be +Z motion)
