Yes coordinates move is why good real time perfomance is required. I guess a pick and place machine would not require hard real time, tell servo to travel to position and wait for it to arrive, this may also increase perfomance because servo could be ran at maximum while for coordinated move it's not possible to move faster than known beforehand. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
