class navigate.model.devices.stage.sutter.MP285Stage(microscope_name: str, device_connection: Any, configuration: Dict[str, Any], device_id: int = 0)

Bases: StageBase, SerialDevice

MP285Stage Class for MP-285.

__init__(microscope_name: str, device_connection: Any, configuration: Dict[str, Any], device_id: int = 0) → None

Initialize the MP285Stage.

Parameters:

• microscope_name (str) – Name of the microscope.

• device_connection (Any) – MP285 stage connection.

• configuration (Dict[str, Any]) – Configuration dictionary for the MP285Stage.

• device_id (int) – Device ID for the MP285Stage.

Raises:

• UserWarning – Error while connecting to the MP285Stage.

• UserWarning – Error while setting resolution and velocity.

• UserWarning – Error while setting absolute operation mode.

Methods

__init__(microscope_name, device_connection, ...)	Initialize the MP285Stage.
close()	Close the stage.
connect(port[, baud_rate, timeout])	Connect to the MP285Stage.
disconnect()	Disconnect from serial device.
get_abs_position(axis, axis_abs)	Ensure the requested position is within axis bounds and return it.
get_position_dict()	Return a dictionary with the saved stage positions.
move_absolute(move_dictionary[, wait_until_done])	Move stage along a single axis.
move_axis_absolute(axis, abs_pos[, ...])	Implement movement logic along a single axis.
report_position()	Reports the position for all axes, and creates a position dictionary.
stop()	Stop all stage movement abruptly.
verify_abs_position(move_dictionary[, is_strict])	Ensure the requested moving positions are within axes bounds

Attributes

Close the stage.

classmethod connect(port: str, baud_rate: int = 115200, timeout: float = 0.25) → navigate.model.devices.APIs.sutter.MP285.MP285

Connect to the MP285Stage.

disconnect()

Disconnect from serial device.

get_abs_position(axis, axis_abs)

Ensure the requested position is within axis bounds and return it.

Parameters:

• axis (str) – An axis: x, y, z, f, theta

• axis_abs (float) – Absolute position value

Returns:

Position to move the stage to for this axis.

Return type:

float

get_position_dict()

Return a dictionary with the saved stage positions.

Returns:

Dictionary of stage positions.

Return type:

dict

move_absolute(move_dictionary: dict, wait_until_done=True) → bool

Move stage along a single axis.

Parameters:

• move_dictionary (dict) – A dictionary of values required for movement. Includes ‘x_abs’, ‘x_min’, etc. for one or more axes. Expects values in micrometers, except for theta, which is in degrees.

• wait_until_done (bool) – Wait until the stage has finished moving before returning.

Returns:

Was the move successful?

Return type:

bool

move_axis_absolute(axis: str, abs_pos: float, wait_until_done=False) → bool

Implement movement logic along a single axis.

Parameters:

• axis (str) – An axis. For example, ‘x’, ‘y’, ‘z’, ‘f’, ‘theta’.

• abs_pos (float) – Absolute position value

• wait_until_done (bool) – Block until stage has moved to its new spot.

Returns:

Was the move successful?

Return type:

bool

report_position() → dict

Reports the position for all axes, and creates a position dictionary.

Positions from the MP-285 are converted to microns.

Returns:

position – Dictionary containing the position of all axes

Return type:

dict

stop() → None

Stop all stage movement abruptly.

verify_abs_position(move_dictionary, is_strict=False)

Ensure the requested moving positions are within axes bounds

Parameters:

• move_dictionary (dict) – A dictionary of values required for movement. Includes ‘x_abs’, ‘y_abs’, etc. for one or more axes. Expect values in micrometers, except for theta, which is in degrees.

• is_strict (bool, optional) – If True, return an empty dict if any axis is out of bounds.

Returns:

a verified moving dict {axis: abs_position}
