Systems and methods for control of excavators and other power machines

A power machine comprising:

• a main frame;
• a work element supported by the main frame, the work element comprising a lift arm moveably secured to the main frame, and an implement interface movably secured to the lift arm;
• one or more actuators configured to move one or more components of the power machine;
• an operator input device configured to receive operator inputs to control movement of the one or more actuators;
• a control system that includes an electronic controller in electronic communication with the operator input device and the one or more actuators, the electronic controller being configured to:
• identify a plurality of response curves for the operator input device, each of which specifies a respective relationship between input signals from the operator input device and control signals for the one or more actuators;
• select a first selected response curve of the plurality of response curves;
• receive, from the operator input device, an operator input that commands movement of the one or more actuators;
• generate a command output, to control of the one or more actuators, based on the received operator input and the first selected response curve;
• and
• modify one or more characteristics of one or more of the response curves based on operator input so as to provide differently modified command outputs based on the one or more of the response curves.
