Lychee Slicer Changelog

All notable changes to the Lychee Slicer development are listed below. Some minor changes and additions maybe not in this list, as well as the internal versions.

Lychee Slicer 3.1.7 Public Beta – 2020-10-14

This new public beta adds variable layer height and transition layers (progressive exposure between burn-in layers and regular layers) for several recent 3D printers like the Sonic Mini 4K or Elegoo Mars 2 Pro (list above).

Added

  • [PRO] New 3D printers for Variable Layers Height (different thickness for your layers). Compatible 3D printers:
    • Phrozen Sonic Mini 4K
    • Phrozen Sonic 4K
    • Elegoo Saturn
    • Elegoo Mars 2 Pro
    • More to come soon
  • Transition Layers: this function makes a smooth exposure time transition from the Burn-in Layers (overexposed layers) to regular layers on the 32D printers listed above. It helps to avoid layers split.
  • Duplicate function in Layout has a new option to keep the layout of the selection.
  • Quick Repair object: fixes the most common 3D model issues without the need to use Netfabb Online repair tool.

 

Changed

  • Recovery function on startup now does the difference between the auto-recovery and the autoload for the previous scene. The popup can be skipped.
  • The default path for the exported slice is set in the folder where the scene is saved.

Fixed

  • Do not select the 3D model when hovering it in the Layout section.
  • Gap found in mini support
  • Update clipping bar on object lift
  • Printer Simulator

Lychee Slicer 3.1.5/3.1.6 Public Beta – 2020-10-09

Fixed

  • Issue when slicing on some new beta Anycubic 3D printers. Artifacts, slicing speed, and file size.

Lychee Slicer 3.1.4 Public Beta – 2020-10-08

We are starting a new cycle of Public betas. These beta versions let you try our new functions and developments, however, ergonomics, interface, the workflow may change and instabilities may occur. Please use Lychee Slicer stable version for production works.

Installing a Beta will deinstall the previous version, including the stable version. You can install again the stable version at any time.

Added

  • [PRO] New “Real” precision mode for Island detection that uses the current 3D printer settings to search for islands: current layer thickness and screen pixel resolution (the Pixel Perfect mode).
  • [PRO] Scale Gizmo in Advanced Support editing mode: when manipulating the Scale cube, you will change the diameter/size of the corresponding selected element of the support. Size is displayed next to the manipulator.
  • [PRO] Angle can be added to the base of the support
  • [PRO] On/Off hollowing switch
  • Auto-Save added: Lychee Slicer now save your scene automatically as a Lychee Slicer Lite scene in a subfolder, located at the same place as your scene file. Saves are incremental.
  • Save reminder: Lychee Slicer reminds you to save your new project after a few minutes and then will start the autosave in the background. A preference lets you disable this function.
  • Select supports by preset, in the Support menu
  • Islands are now visible in the Clipping bar.
  • Adding/connecting manual supports to the tip on existing support is now allowed.
  • Light/Medium/Heavy presets hotkeys (CTRL+1/2/3)
  • Supports visibility management in the View menu: you can now hide, unhide, isolate supports.
  • Values are automatically highlighted when editing a parameter: type the new number to replace the previous one and hit Enter to validate
  • Export Lychee Slicer Scene is now also available in the Export section.
  • 3D Printer/Resin/Layers information in the Export section
  • Cancel button on during the repair process with Netfabb
  • New menus and sub-menus in the Support section of the application
  • New preference to hide the help floating window, located at the bottom of the window in the Support section.

Lychee Slicer 3.1.2 – 2020-09-25

This version fixes an issue of the fix. We are sorry that we missed that one!

    Lychee Slicer 3.1.1 – 2020-09-25

    This version fixes only an issue that was preventing in very specific circumstances some Lychee Slicer scenes to load. The problem was only a loading issue and was not corrupting data.

      Lychee Slicer 3.1 – 2020-09-16

      This version is the first stable release of Lychee Slicer 3.

      Added

      • New Lychee Slicer lite *.LYT file format includes only data from Lychee Slicer (Supports, etc.) but not the 3D models that have been loaded in the scene. The 3D files must be supplied with the LYT file, the 3D models being an external resource.

      • [PRO] Change the 3D Printer screen size by +/- 2% in the 3D printer settings. It can be useful for users who need compensating resin shrinkage.
      • 3D model topology error detection on loading: Lychee Slicer will now warn you if an object has topology/structure issues on loading and will display them in red in the Layout and Preview rooms. Please fix them before slicing them.

      • Activation email can be resent from the user control panel.
