At times controllers can have a problem of alternating between short and long parts as the missing material from a short part gets added to the next part, making the next part more likely to be long. Even if the next part cuts perfectly in the right place it will be long because the prior part was cut in the wrong place, short.

On shear only controllers a method used to counteract this is to reset the encoder count on every shear to match the expected shear target from the part queue. This gives each part a fresh start. Each part has an equal chance to be accurate without the prior parts accuracy impacting it.

This technique is only valid if there are no other queue targets for other presses that would be negatively impacted. It is also not valid if you have a hole queue of detected holes that have been captured based on the current encoder count. Adjusting the encoder count effectively changes where those holes have been detected. This oversight has now been corrected.
