Level COMMAND (LC) is a GNSS-based machine control software operating environment developed by T3RRA for construction, earthmoving, and landforming machinery. Operating together with the COMMAND hardware platform, Level Command provides terrain visualisation, ...

Armed Automatic control is enabled and ready to assume implement control when engagement conditions are met. Benchmark A known reference position or elevation used to align or verify machine position relative to the active project or terrain surface. Blade Shi...

Loading a Design File To load a design file, press Done at the top-right to return to the Level COMMAND apply page, then press More > Load Project. This will open the Change Project page and display all .tad file projects. This file type is specific to LC and ...

Before Engaging Automatic Control Before engaging Automatic Control, verify that: ✓ A project is loaded. ✓ GNSS receivers have achieved RTK fix. ✓ A valid zero has been established. ✓ COMMAND Status displays Ready to Engage. Ready to Engage indicates that all ...

Understanding the Operator's Role Level COMMAND automatically controls the implement to follow the selected design surface, but it does not decide where material should be moved from or where it should be placed. The operator remains responsible for planning t...

To access COMMAND ECU settings from the Apply View, press "More" at the right side of the screen, then "COMMAND Settings". The COMMAND Settings Overview page shows each page related to operation of the ECU. The Machine page is used to setup the connection be...

Profile The profile is used to select the type of implement being used, for detailed information on available profiles please refer to the COMMAND hardware manual section.     After selecting the appropriate machine profile, enter a Blade Width in the field s...

The Inputs/Offsets page is used for selection of input sensors, such as GNSS receivers for height control or Inertial Measurement Units (IMU) for terrain compensation and Tilt / X-slope control. GNSS Input Configuration Pre-configuration Before configuring Le...

The Valve Configs page is used to set up the control output interface for each control function. Appropriate signals of that interface type are then generated when automatic or manually controlling the implement. External joystick inputs are also configured o...

Valve Threshold Calibration establishes the minimum and maximum hydraulic outputs used by Automatic Control. Correct calibration ensures the implement can move smoothly for small corrections while still achieving full operating speed when required. Access the ...

Overview Cylinder Ratio Calibration compensates for differences in implement movement speeds between opposing control directions. Hydraulic systems rarely move at identical speeds in both directions. Differences in cylinder geometry, implement weight, hydrauli...
