reversal position 1,
Set the axial override of the infeed axis to
100%
Set the axial override of the infeed axis to
0% (so that the second synchronized action
is cancelled once!)
; Assign axis X to the oscillation axis Z as
; infeed axis, this should
; infeed to end position 5 in steps
; from 1 and the sum of all part lengths should
; give exactly the end position
