Hi Jon !
Why set up the kinematics ? I just want to drive a "simple" 5-axis-mashine ,
no Hexapod and no robot.
3 linear axis ( X,Y,Z) and two rotary axis (B,C ). The wright kinematic is
figured out by the postprocessor of the programming system.
Using G01 X100 Y50 Z30 B10 C20 all axis should start and finish their way at
the same time. X,Y,Z moving in mm, B,C in degrees.
With the ZIPEMC-CD I was told it works only 3-axis interpolating, 4th Axis
only in "Jog".
Then, perhaps 6 weeks ago (or so) someone announced EMC would now be working
for 5 (or 6?) axis.
But the newest EMC - Version I can find is older than that.
( If it is of intrest - I´m working as an CNC-Programmer at www.praewest.com
( look at the produktion/quality assurance ))

Peter
