Release Notes

G-coordinator ver3.0.0

Note

This version is a major update from ver2.0.0. Due to the lack of backward compatibility with version 2, some adjustments are necessary for the modeling code created in version 2 to work with version 3.

The internal G-code generation process has been standardized to the gcoordinator library version 0.0.14. As a result, some aspects of the fabrication code processing have been modified.

In G-coordinator ver2, the code for shaping was written inside a function called object_modeling(). In ver3, that restriction has been removed, and now shaping can be done through the execution of pure Python code.

By passing the list of path objects, full_object, to the gui_export() function, you can preview and export G-code within the application.

# ver2 series code
import numpy as np
import print_settings
from path_generator import *
from infill_generator import *

def object_modeling():
    full_object=[]
    for height in range(100):
        arg = np.linspace(0, 2*np.pi, 100)
        x = 10 * np.cos(arg)
        y = 10 * np.sin(arg)
        z = np.full_like(arg, (height+1) * 0.2)
        wall = Path(x, y, z)
        full_object.append(wall)

    return full_object

# ver3 series code
import numpy as np
import gcoordinator as gc

full_object = []
for height in range(100):
    arg = np.linspace(0, 2*np.pi, 100)
    x = 10 * np.cos(arg)
    y = 10 * np.sin(arg)
    z = np.full_like(arg, (height+1) * 0.2)
    wall = gc.Path(x, y, z)
    full_object.append(wall)

gc.gui_export(full_object)

Furthermore, there have been slight changes in the way functions like Path(), Transform class, and gyroid_infill() are called. To avoid namespace pollution, it is recommended to access objects from the gcoordinator library by calling them through the gc alias.

# ver2 series code
from path_generator import *
from infill_generator import *

wall = Path(x, y, z)
outer_wall = Transform.offset(wall, 0.4)
infill = gyroid_infill(wall, infill_distance=2)

# ver3 series code
import gcoordinator as gc


wall = gc.Path(x, y, z)
outer_wall = gc.Transform.offset(wall, 0.4)
infill = gc.gyroid_infill(wall, infill_distance=2)

In version 3, code refactoring was performed to streamline the complexity of the code, leading to certain functions being restricted or deprecated. Specifically:

• Functionality to access parameter tree values in the editor

• The print() function in the editor

• The Transform.fill() function

These features are not included in ver3.0.0; however, we plan to reintroduce them in a more improved form through future updates.
