Re: [CAD_CAM_EDM_DRO] Re: was, Steel plate for hexapod setup questions

highschool trig is the basis of all movement.
a 6 axis gantry is more complicated than a hexipod

the fun is the logistics of dealing with tool offsets backlash and the millions of other toolpath tweaks not to mention safety interlocks and the like

Just thinking about this hexapod principle and a few questions immediately come to mind. How does it know X from Y? Does the operator mount a workpiece and pick up different points of geometry to reference? For instance, all four corners of the top of a block. Seems that the block or workpiece would have to be of perfect proportion. How does it know when the axis of the spindle is at 90 degrees etc. to the work surface? Home reference hard limit on each actuator to reference zero's? Is there a special software that calculates the pulse train to each actuator for just a linear move? Seems like it would be a nightmare to program. Alot of calculations even to do simple movements. Of course, the 3-D for modeling capabilities etc. would make it a worthwhile endeavor. Something to consider, if this software could be used in reverse and replace the actuators with linear scales it would be a rather crude ...tadaaa!!! CMM machine. :-)
