PrusaSlicer 2.6.0-beta1

PrusaSlicer

Summary

This is the first beta release of PrusaSlicer 2.6.0, mostly fixing bugs found in the previous alphas. See the release logs of 2.6.0-alpha2 ↗, 2.6.0-alpha3 ↗, 2.6.0-alpha4 ↗, 2.6.0-alpha5 ↗, and 2.6.0-alpha6 ↗. for the complete list of changes with respect to 2.5.2.

With this release, PrusaSlicer not only brings fixes but also introduces several noteworthy improvements to existing features. Highlighting the most significant enhancements, the Cut tool has been upgraded to provide increased power and functionality, Organic supports have undergone improvements to enhance stability and reliability, and modifications have been made to improve compatibility presets for multitool printers.

To let you enjoy the beta without worries, the beta builds save their profiles into the PrusaSlicer-beta directory, so you may use the beta side by side with the current release without ruining your production configuration. When you first run the beta, it will search for all configurations produced by alpha or final versions and offer to create a copy of the latest one.

Upgrades of the Cut Tool for selective object splits #9472, #9577, #9922,

The improved Cut tool now offers more flexibility by allowing users to selectively select parts of the object which should not be cut. Selection and deselection of the parts can be controlled with the right mouse button. Note that when some parts are selected, PrusaSlicer will always generate two separate objects, the option to leave everything as parts of one object is not available. Cutwithconnectors_improvements2

Changes in modification of compatibility of presets

When using a Multitool printer (with 'singleextrudermultimaterial' turned off), PrusaSlicer now filters filament presets and presents the user with only the appropriate filaments based on the compatible printers conditions ('compatibleprinterscondition') for each individual extruder. This change also introduces a new combobox in the Filament settings, simplifying the listing of extruders. FilamentBar

Other improvements with respect to 2.6.0-alpha6

• Embossed text objects can now be edited in Simple mode.
• When using MainSail/Fluidd print host, PrusaSlicer now uses Moonraker API, without relying on OctoPrint compatibility mode being enabled.
• A new ‘Hide/Show Custom G-Code’ button was added to the G-Code preview. The range of color scale in the legend is possible to visualize without the effect of the purge line. The button is available only for parameters where it is relevant (Width and Volumetric flow rate) #10259
• Improved error reporting when the last layer exceeds the maximum build volume height due to variable layer height. The name of the object violating print height is reported. Improvement is related to original issues. #9467 #9519 #9646
• macOS specific: Fixed performance issue with the G-Code viewer when travels were enabled.
• Added 'Zoom to mouse cursor' by Shift+Mouse wheel. Thanks to @LiZ-Li-BBL
• Thumbnails generated to G-code now use the same colors as in the 3D view. #4577
• The slicer now includes an improved algorithm for overhang speed slowdown and avoiding curled filament. A new and tuned estimation method is applied for the curled height of the filament. The estimated curling now affects the slowdown of overhang speed on external perimeters and also on internal ones. #9756. The new enhancement should significantly improve surface quality and prevent artifacts, without slowing down internal perimeters unnecessarily.
• After slicing an object with negative volumes in SLA mode, users now have the ability to toggle the visualization on or off, allowing for better control over the final geometry in the 3D editor. This convenient new button for switching between visualizations is located adjacent to the object, facilitating an intuitive user experience.

SLAbuttonmerged

• New ensuring addresses the occasional occurrence of local zig-zag patterns that were generated in the ensuring perimeters. It detects segments with short movements that cause vibrations and can reduce surface quality, and fixes them. #9970
• Improvement of Organic supports by preventing collisions between the main object and its own support branches. Note that the collision issue between different objects and their support branches remains unresolved. #10247
• The bottom interfaces of Organic supports have been fixed and enabled, providing enhanced stability when positioned on the model's body. #9512
• The user now has control over the utilization of either one or two perimeters for Organic supports using the supporttreebranchdiameterdouble_wall parameter. #10304

Improvements in bridges over internal infill

• Improved the algorithm so it does not generate extremely long bridges when the layer below is very sparse. #10222
• PrusaSlicer now detects areas where internal bridges require anchoring to perimeters and enhances it by adding an extra ensuring line in the previous layer. This addition provides support and enhances structural stability for the bridges.
• Furthermore, PrusaSlicer has improved the handling of internal bridges when using Lightning infill. It expands the Lightning infill around bridged surfaces, ensuring improved anchoring for a greater number of bridges.
