spectral_galerkin_heat.io_utils.gcode_path

G-code parser for laser path extraction.

This module implements a lightweight G-code interpreter that extracts linear segments, timing, and laser power commands and exposes them via the GCodeLaserPath implementation of LaserPath.

Classes

GCodeLaserPath

Abstract laser trajectory: position and power as a function of time.

Module Contents

class spectral_galerkin_heat.io_utils.gcode_path.GCodeLaserPath(gcode_file, initial_position=(0.0, 0.0))

Bases: spectral_galerkin_heat.core.laser.LaserPath

Abstract laser trajectory: position and power as a function of time.

Implementations return a LaserState per time step (consistent units: metres, watts, m/s). Set is_on=False (or power 0) once the laser leaves the domain.

Example

>>> class ConstantVelocityLaser(LaserPath):
...     def __init__(self, x0, y0, vx, power):
...         self.x0, self.y0, self.vx, self.power = x0, y0, vx, power
...     def get_state(self, time, dt):
...         return LaserState(self.x0 + self.vx * time, self.y0,
...                           self.power, is_on=True, v=(self.vx, 0.0))

Parameters:

gcode_file (str)

get_state(time, dt)

Return the LaserState at time (called once per time step).

Parameters:

• time (float) – Current simulation time in seconds (monotonically increasing).

• dt (float) – Current time-step length in seconds.

Return type:

spectral_galerkin_heat.core.laser.LaserState
