Abstract
A system and method including a scraper may include an operator training routine using in-cylinder position sensing to notify the operator via an operator interface (e.g., mounted onboard display, smartphone, etc.) when they are doing something potentially damaging to one or more scraper components or otherwise injecting inefficiency into work operations. Audible and/or visual notifications may for example be enabled for operators of/below a specified skill level, for specified movement speeds, etc. In an embodiment, to utilize advanced automation capabilities of in-cylinder position sensing, a calibration sub-process is executed to specify a location of the ground plane. The scraper ground plane calibration is requested through an operator interface and prompts lowering of the blade to the ground. Once the blade is detected on the ground plane, e.g., using measured movement characteristics of the blade to determine that the blade has stopped, the in-cylinder position sensor reading is recorded.
