I've got something very strange going on. I have a BP clone that had
a Anilam crusader servo system on it. I replaced the crusader logic
stuff with 3 rutex 0-10v analog drives and Mach2. I'm still using
the glass scales as the encoders. I used the rutex tuning program
and have nice wave patterns with no over shoot. When I move the X
or Y axis the table stops on a dime. When I move the Z axis it seems
to over shoot by .010" and then slowly returns to where it is
supposed to be. The DRO readouts don't relect this change. If I use
the incremental jog and make a move as little as .0005 it still over
shoots by .010 I`ve tried messing around with the adjustments on
the rutex drive but I cant seem to get it to make any difference. Is
it possible I need to make an adjustment at the servo amp itself?
I'm not loosing any position on the axis.
Thanks
Derek
