Configuration

Variable	Required	Secret	Description
GEAROTONS_MOTOR_BACKEND	—	—	'auto' (default: real serial backend when the servomotor library is installed, otherwise the simulator, which says so in list_serial_ports), 'serial', or 'mock'. For real motors install servomotor-mcp[serial].
GEAROTONS_SERIAL_PORT	—	—	Optional default port for the connect tool (e.g. /dev/cu.usbserial-210, /dev/ttyUSB0, COM3). Normally unnecessary: the model discovers ports with list_serial_ports.
GEAROTONS_DEFAULT_SPEED_DPS	—	—	Default speed in degrees/second for the high-level move tools.
