A customer complained that the Stitching feature was not putting in a full cut on the last part.

The customer sent in an example order. The final Stitch parts were 36" long and the last item had six of these parts in it. The Min Auto Stitch Length was 72" and the Max Auto Stitch Length was 144". The controller stitched four parts. The last two parts combined to equal the Min Auto Stitch Length.

At the end of an Order or when the Stitch Mode setting requires a full cut, the controller will add scrap if it needs to in order to bring up the resulting blank to the Min Auto Stitch Length. The controller had a bug in the code that tries to add the scrap piece. It tried to add a short sliver that I believe got ORed together with the last stitch cut.

Two changes were made. If no scrap cut is necessary, the controller will clear the stitch gag of the last part added to the queue. If a scrap cut is necessary the controller will compare the scrap cut first to the Min Auto Stitch Trailer Length. The scrap will be no less than this length. If the Min Auto Stitch Trailer Length is zero the Minimum Part Length will be used to set the minimum scrap length part that gets added to do the full cut.
