Moisture damage to cotton results in serious economic losses to both producers and ginners. Previous research has demonstrated that poorly shaped modules, which have depressions in their surfaces where water can collect, are a significant cause of reduced lint value and increased ginning costs due to higher moisture levels. A system was developed to provide graphical feedback to the module builder operator about the module shape that would result from leveling and tramping actions.

Improvements to the system were made to increase the accuracy of the system in locating the position of the carriage. Proximity sensors were used to determine the distance and direction of rotation of the carriage drive shaft. Data was collected from the system to determine if the desired graphical output occurred during the module building process.
