This is OrcaSlicer V2.1.0 beta release.

What's Changed

• Orca Slicer now features brand-new icons, thanks to @yw4z in #4368
  These icons are designed to be more consistent, modern, and pixel-perfect, offering better color contrast. They align seamlessly with the new design of Orca Slicer. A big thanks to @yw4z for these new icons and numerous UI improvements!
  

• Orca Slicer now support open/import model from Prinables.com/Thingiverse.com/makerworld.com directly by @SoftFever and @Ocraftyone (#5486, #5416, #3823)
  No more manual downloads! You can now open models directly from these sites, and Orca Slicer will automatically import them for you.

  
  
  

  You can enable this feature in the Preferences dialog.
  Please note that this feature is currently available only for Windows.

• Infill direction enhancements by @SoftFever in #5267
  With the new enhancements, Orca Slicer now allows users to set sparse and solid infill directions independently. Users can also disable solid infill direction rotation, which is particularly useful when printing with transparent materials.

• Port new sparse infill pattern Cross Hatch and optimization by @SoftFever in #5495

  In this release, a new infill pattern called CrossHatch has been introduced into Orca(thanks to BambuStudio). This pattern is similar to Gyroid and the new 3D HoneyComb introduced in OrcaSlicer 2.0 RC but offers even faster printing speeds. Orca has further optimized this infill pattern to enhance its performance at low infill densities.

  Before:
  

  After:
  

• improve seam performance by @SoftFever in #5436
  
  

• Support larger printer by @SoftFever in #5320
  Orca Slicer previousely only support printer bed sizes smaller than 2147mm x 2147mm due to the limitations of the 32-bit data type.
  This limitation also applies to the maximum number of platers you can create for a project.
  The total width/length of all the plates cannot exceed this limit.
  Orca Slicer now support sizes as large as desired.
  For convenience, the limit is currently set to 214m x 214m x 214m.
  SuperSlicer is referenced for some changes.
  

• ESP3D printer connection for wireless printing by @PreyK in #5399
  Added ESP3D support for wireless printer connection to be able to send gcode & start printing directly from the slicer on printers with ESP3D module.
  

• fix wrong overhang slowdown value by @SoftFever in #4940

  Fixed a bug that overhang slowdown may slowdown too much in some cases.
  before, it slowed down to 4 mm/s despite we had minimal speed to 10:

  

  after:

  

• SEMM: Introduced parameter to control the maximum speed used for purging in the purge tower by @igiannakas in #5304
  Previousely the speed limit is set to 90mm/sec which works well; however speed gains can be made by increasing this if the printer is able to bridge at higher speeds in the wipe tower.
  A max speed limit has been introduced for the purge tower. The existing, as is limits of volumetric flow for the filament and sparse infill speeds are respected. Same for the ramping up of purge speed up to the limit.

• Adjustable infill wall overlap for top and bottom surfaces by @igiannakas in #4832
  This new option allows for independent adjustment of the infill/wall overlap for internal solid and sparse infill and top and bottom surfaces.

• Touchpad-friently 3d navigation by @buzzhuzz in #4598
  Implement FreeCAD-inspired touchpad navigation mode.
  This mode makes 3d model inspection easier for devices with touchpad as the only pointer device.
  Controls:
  Shift+move: panning
  Alt+move: rotation

• Orca Slicer default parameter tweaks by @SoftFever in #5406
  Some parameters are tweaked to improve the print quality and speed for all printers
  Gap fill are now disabled by default
  top_surface_pattern are not default to Monotonic Line
  Sparse infill pattern are now default to Cross hatch
  etc

• Fixed a bug that top surface was mistaken as bridge in some cases by @SoftFever in #4678

  

• Precise Z Height

  
  When enabled, this option ensures the accurate Z height of the model after slicing, even if the model height is not a multiple of the layer height.
  For example, slicing a 20mm x 20mm x 20.1mm cube with a layer height of 0.2mm would typically result in a final height of 20.2mm due to the layer height increments. By enabling this parameter, the layer height of the last five layers is adjusted so that the final sliced height matches the actual object height, resulting in an accurate 20.1mm (as shown in the picture). This feature is ported from BambuStudio.
