System and method to reload net roll or partially used net roll in round balers

A round baler comprising:

• a baling system defining a baling chamber having an access into the baling chamber, wherein the baling system is operable to receive crop material into the baling chamber through the access and form the crop material into a bale within the baling chamber;
• a wrap system operable to insert a wrap material through the access and into the baling chamber to wrap the bale, the wrap system including:
• a supply roll having wrapping material thereon;
• a support structure configured to support the supply roll of the wrap material relative to a pair of spool rollers;
• a sensor arranged to sense the supply roll of the wrap material, wherein the sensor generates a sensor characteristic relative to a length portion of the wrap material dispensed from the supply roll;
• and
• a controller operably coupled to the sensor to receive the sensor characteristic, wherein the controller includes a computing device having a processor and a memory having one or more of a calibration control algorithm, a reload net roll control algorithm, and a reload partial net roll control algorithm stored thereon, and wherein the processor is operable to execute at least one of the calibration control algorithm, the reload net roll control algorithm, or the reload partial net roll control algorithm to:
• determine whether the sensor characteristic from the sensor is within a first threshold amount of a minimum sensor characteristic of the sensor;
• determine whether the sensor characteristic from the sensor changed more than a second threshold amount;
• and
• determine a partial supply roll of the wrap material that includes less than a maximum length of the wrap material is loaded into the wrap system when the sensor characteristic from the sensor changed more than the second threshold amount.
