Destack parameter to describe how empty stations are used
The default value of this parameter is Y.
If the last part cut from a pattern completes the part type (no more of those parts are cut in subsequent patterns - STILL TO CUT = 0) the station at which the part is destacked is NOT free for destacking until the first part is cut from the next pattern. This allows the user time to off-load that station.
When this parameter is set to N this restriction does not apply.
It is usual to set this parameter to Y (for yes) but this may mean in some cases that parts may go to the overflow station (if no stations are free) in which case a setting of N may result in the overflow station not being needed.
