v4.10.0

Nov 15, 2023, v4.10.0

Laser Parameter Additions

Snapmaker Luban v4.10.0 updated the engraving parameters for pictures and graphics. With finely tuned parameters, intricate patterns and complex designs can now be engraved with greater accuracy

• Dot Width Compensation is able to optimize the toolpath based upon the size of the laser dot to reduce contour deformation and blurs.
  
• Over Scanning is used to solve under and over burns from acceleration and deceleration phases.
  
• Scanning Offset designed to reach better results in cases where there is a large mechanical backlash or when the design to be engraved is intricate with rich details.

Mesh Painting Tool & Multi-color Model Slicing

In response to user requests, we have now added Mesh Painting Tool & Multi-color Model Slicing similar to PrusaSlicer's Multi material painting.

In GUI, you can apply two distinct colors to the mesh, each representing two different materials.
To support this new functionality, we have adapted our slicing engine, ensuring it can handle the slicing of these newly colored meshes.

Luban provides two tools, Smart Fill and Brush, to accomplish mesh coloring.

• Smart Fill: Depending on the angle of the triangles in the clicked area, select triangles with a range of angular tolerances around the connection.

• Brush: Triangles are selected based on the triangles and angular tolerances that the spherical brushes come in contact with. Smaller angle tolerances detect sharp borders, allowing the brush to paint only the area within the edge. The opposite is true for larger angles, where a 90° tolerance allows the brush to recede to select all triangles touched by all spherical brushes.

In terms of shortcut operations, it supports numbers 1 and 2 to switch color selection quickly, and Ctrl/Command + scroll to quickly resize the brush.

The undo feature and preview of colored areas are still under development. They will be completed in future versions.

Model Split Tool

For models that are composed of multiple meshes, they can naturally be assigned to different extruders without the need for coloring. In that case, we provide a split tool that allows you to split a single STL file composed of multiple meshes. This makes it easier to allocate different extruders to each segment.

Online Case Library

Considering the scarcity of multi-material models, we have created an online case library to share models suitable for multi-material printing. Currently, the resource quantity is limited, but we will gradually increase it. In the future, we plan to add sections for Laser and CNC, and make it accessible to everyone.
