class gcode_reader.emulate.machines.baam.BAAMMotionProfile(max_jerk=None, max_accleration=None, max_velocity=None, max_velocity_z=None, max_velocity_w=None, junction_deviation=0.05)[source]

Bases: gcode_reader.emulate.motion.MotionProfile

Factory for generating MotionSegment objects from process data.

Holds machine-wide kinematic constraints and orchestrates a two-pass (GRBL-style) velocity planning algorithm: junction-deviation corner limiting followed by forward and backward kinematic propagation.

Parameters:

  • max_jerk (float, optional) – Maximum allowed jerk (units/s³). Used only by SCurve segments. Defaults to None.

  • max_accleration (float, optional) – Maximum allowed acceleration (units/s²). Defaults to None.

  • max_velocity (float, optional) – Ceiling on all target velocities (units/s). Defaults to None.

  • junction_deviation (float, optional) – Junction-deviation parameter (same length units as positions). Larger values permit higher corner velocities. Defaults to 0.05.

feed_rate_time_base_s

Divisor applied to feed-rate values to convert them from units/minute to units/second. Defaults to 60.0.

Type:

float

max_velocity_z = None
max_veloicty_w = None
class gcode_reader.emulate.machines.baam.CincinnatiBAAM(**options)[source]

Bases: gcode_reader.emulate.machine.Machine

An emulation environment for a Cincinnati BAAM (Big Area Additive Manufacturing) machine.

This class extends the generic Machine to include BAAM-specific behaviors: 1. 4-Axis Coordinate System (X, Y, Z, W): It handles the W-axis,

which acts as a dynamic Z-offset for the build plate. The final Z position is calculated as Z_command - W_command.

  1. Custom M-Codes: It processes BAAM-specific G-code commands for extruder control (M3/M5), parking (M68), etc.

Initializes a new Machine instance.

Parameters:

  • tools (Tuple[Tool, ...], optional) – A tuple of Tool instances for the machine to use. Defaults to None.

  • parser (GcodeParser, optional) – An instance of a GcodeParser. Defaults to a new GcodeParser().

  • exporter (GcodeExporter, optional) – An instance of a GcodeExporter. Defaults to a new GcodeExporter().

  • **options – Keyword arguments passed to the constructor of the machine’s MachineOptions type.

clear_history()[source]

Clears history and resets BAAM-specific state.

gcode_file_to_operation(filepath: str, operation_type=AdditiveOperation)[source]

Parses a G-code file and returns a processed Operation.

This method uses the machine’s configured parser to read a G-code file into a list of commands, wraps them in the specified operation_type, and then processes the operation to populate its process data.

Parameters:

  • filepath (str) – The path to the G-code file.

  • operation_type (type, optional) – The class of Operation to create (e.g., Operation, AdditiveOperation). Defaults to Operation.

Returns:

A new, processed Operation instance.

Return type:

Operation

Raises:

ValueError – If operation_type is not a valid subclass of Operation.

process_operation(operation: gcode_reader.emulate.operations.AdditiveOperation, force=False) → gcode_reader.emulate.operations.AdditiveOperation[source]

Fully processes an additive operation, including a second pass for extruder data.

This method extends the base Machine’s processing pipeline to accommodate the ScrewExtruder’s dependency on accurate time estimates for its calculations.

The process is as follows: 1. It first calls super().process_operation(), which runs the full

kinematic simulation and applies the motion profile. This is the critical step that calculates and populates the elapsed_time for each movement command.

  1. It then performs a second pass, iterating through each command and its now time-aware process_data. This allows the extruder tool to use the elapsed_time to accurately calculate deposited_volume.

Parameters:

  • operation (AdditiveOperation) – The additive manufacturing operation to process.

  • force (bool, optional) – If True, re-processes the operation even if it has been processed before. Defaults to False.

Returns:

The operation with fully populated process data,

including time-dependent extruder calculations.

Return type:

AdditiveOperation
