In this blog post, we will be going over some of the recent updates to the dxf2-import functionality that we have previously mentioned here. To recap, we have been working on an improved version of DXF import, primarily for plasma cutting applications.

Since the time that we have posted our last blog post, we have completely overhauled the visuals of the new DXF import window:

The system is now split into the CAM module (useful for bringing in existing DXF files and built-in shapes) and the CAD module (for designing shapes and drawings from the ground up). Pictured below is the CAD module:

The CAD module provides a simple and straightforward way for drawing simple shapes (circles, arcs, rectangles, lines and splines), finding line intersections, scaling and rotating contours, adding text, as well as importing DXF files which can then be edited by hand. After the design stage has been completed, these drawings can then be imported from the CAD into the CAM module. There, the user can edit leads, adjust the cut sequence, set custom kerf (cut width) correction values for different contours, as well as nest the imported figures.

Nesting is done by switching into the Nesting tab in the CAM module. Here, the user can specify the sheet size, the distance between parts as well as the possible angle for the rotation of the nested shapes. Pictured below is a file with multiple built-in shapes before nesting:

The next screenshot shows the same project after the automatic nesting procedure has been applied:

We have also added the ability to save and re-open CAM/CAD projects, the ability to specify custom speeds for specific contours, enabling/disabling and automatically assigning DXF file layers to particular speed and kerf values, as well as other quality of life features such as the Undo command and autosave within the CAD module. If you'd like to switch to the new dxf2-import functionality, you can update the myCNC software and follow the steps in this guide to get started.

Stay tuned for further updates!
