2.5.59.12

New release to mainly fix two important bugs that are crashing the software.

known issues

• some problems with windows 11 #3985 #4071
• some open issues are reported for 2.7 build #4045 #4037 #4036 #3996 #3923
• If you have problem with macos, check that post

bugfixes

• fix crash when the first object isn't the tallest #4309 #4313
• Fix crash when wipe into collapsed area #4301
• should be able to import step files on linux
• the search now display & can show you the frequent settings.
• allow variable with paths (thin walls, gap fills) to be printed in the reverse direction if allowed and useful to reduce travels.
• fix brim on first support layer (when it's not on the bed) #4300
• fix bad support grid #4306
• Fix seam notch for outer perimeters. #4305

notes

I haven't tested the linux & macos build.
The mac intel version will ask you for permission, and the arm will tell you it's corrupted. You need to do xattr -cr /Applications/SuperSlicer.app.
For Windows automatic installer/updates: https://community.chocolatey.org/packages/superslicer . Note that it has some days of delay, for the validation process. (I'll try to add superslicer also into winget)

Seaworld Edition

Hello, here a new 2.5 version with many bugfixes.
2.7 merge still ongoing, but I wanted to finish stabilizing the 2.5 on january. Going to focus more on the 2.7 in February.
There may be a stable 2.5 after this one.
On my personal front: I'm now employed at 80% for a 3D printer company to work on superslicer. That means I can focus my energy on it.
These 80% are used to work on testing, merging newer version of superslicer & orcaslicer, and new features that are needed by the company.
The 20% left is to be able to work on other features, and for features wanted by other companies.

known issues

• opening a project don't load spacing settings #4117
• problem with windows 11, you may want to remove the opengl32.dll from the mesa dir if you have problem with your graphic card, as a stop gap (this disable the 3D acceleration).
• still no mac build, will do that after 2.7 merge. For now, you can grab the mac-intel nightly from here, it's the same but without the translations.
• some pending issues that are difficult to reproduce or fix, or I just didn't had the time : #4071 #4045 #4037 #4036 #4039 #3996 #3923

New

• Import project from other slicers:
  • OrcaSlicer (&bambu): first implementation (reusing their import code) : now you can import an Orca project (.3mf) like you can do with prusaslicer project (.3mf).
  • new preference (show_unknown_setting) to hide the pop-up that inform you about settings that are unknown (and so ignored) when importing a project file.
  • PrusaSlicer : fixed conversions issues
• Avoid crossing perimeter:
  • use the better surface shrink from PrusaSlicer
  • now can pass on top surfaces if needed (new setting)
  • now can follow the external perimeter to avoid top surfaces
  • can go over top surface at the start & end if the distance is much less than the strait travel (rare case)
• Scripted widget: now can have dependencies in other tabs & update all values of a vector instead of the first one.
• Fix concurrent script execution.
• update profiles (pr integrated) (no 2.7 changes yet)
• new setting: gcode_ascii for ascii-only output (replace other char by '_') #4070
• Double slider anti-miss-clicks adjustments: #4075
  • Push the (+) color change button as far away as possible
  • Add a little dead zone between the bottom and the lock icon.
  • Also fix a crash that can happen when a color change is done and the computer is a bit slow.
• Allow enum values as output string in placeholders. #4098
• Gcode viewer: when looking at volumetric flow, you have now in the legend a button to hide outliers values (often the purge line from start gcode).

General Bugfixes

• fix XY size compensation direction for inner & holes (some were going the wrong direction, again, sorry for that. Unless my brain fart again? It seems there is always one that goes in the wrong direction, It's hard to judge, so i'll implement some unit testing to fix it onece for all)
• Updates unit testing find some bugs:
  • fix a 2-4% overextrusion for small infill areas, as the overlap was added two times instead of one.
• fan mover: little fixes, now can work with G2 & G3 (will not split them, and the distance is an approximation, but good enough) #4061
• Fix cooling (post-process) parsing issues
• Better handling of too small extrusions for thin_walls_merge & no seam on the thin walls (unless it's a thin wall perimeter loop).
• Fix 0 acceleration for reprap #4048
• Fix artifacts from mmu paint #4101 (again)
• Check for fimware compatibility with M73 & M117 (warning)
• fix save .3mf with pattern modifier #3549
• Maybe fix BIQU / BTT_TFT thumbnail (using orca knowledge & code)
• Calibrations
  • now accept preferred orientation (init_z_rotate) #4099
  • Fix retraction calibration solid fill areas #4097
• reworked parallel_objects_step to be able to print objects instances in sequence. #4043
• fix parsing utf-8 for not-alphanumeric chars #4070
• change exception to warning log for AppConfig::save() on badly named thread. On win11, the vent thread doesn't have the right name? Need more investigation. #4046
• Fix macos start error (bad icon path) #4095 (maybe?)

Settings Bugfixes

• Fix default object & region config apply for gcode creation. Also move brim_speed from region_config to object_config #4050
• disable external_perimeters_vase if perimeter_loop #4027
• Fix wrong compute of width from external perimeter spacing. #4082
• print_extrusion_multiplier now correctly split regions. #4108
• Fix loading preset with wrong keys erasing good preset values. #4079
• no retract if before_wipe with length 0
• Fix infill speeds in modifier don't work if not altering the full layer #3849
• fix only_one_perimeter_top for arachne #4041

Gui Bugfixes

• Fix Seam gap in filament section keep reactivating #4065
• Bed texture fixes:
  • if vendor has only texture or model, still show it.
  • png texture can turn black on compression on some hardware (amd). A new preference (compress_png_texture) is now available to disable the optimisation that can cause that. You have to relaunch the app to force the reload of the texture or: remove it, go to platter, then re-add it.
• fix crash on one-layer object (doubleslider)
• fix tip of day moving you to setting tab #4055
  • fix filament cooling description crash when no fan is enabled #4047
• fix custom string variable without quotes #4011

• fix NULL dereference on wxWidgets 3.2 by @Icenowy_Zheng
• fix filament compatible widget #4073

Localisation

• it localisation
• spanish calibration

Happy New Year edition

The 2.7 version is not ready, so here is a new 2.5 version, that should work even better than the previous one.
I'll probably do another 2.5 version in 2024, to be able to have a stable one.

known issues

• problem with windows 11, you may want to remove the opengl32.dll from the mesa dir if you have problem with your graphic card, as a stop gap (this disable the 3D acceleration).
• still no mac build, will do that after 2.7 merge. For now, you can grab the mac-intel nightly from here, it's the same but without the translations.

New

• italian translation update
• Make preferences resizeable, with scrollbar, and fit small screen #4028

Bugfixes

• Fix layout (crash when displaying some filament fields) #4031 #4030 #3991 #3976
  • now using the one in the resources.
  • If you want to use the same configuration directory with versions older than 2.5.59, you can erase the configuration_dir/ui_layout directory manually. Don't share a configuration directory with 59.3, 59.4, 59.5.
  • Note: it may be problematic to share a configuration directory between versions, as saving a profile in an old version can delete the new settings from the newer version. You can set your configuration directory by creating a configuration directory next to the superslicer.exe or with the --datadir="my/path" option
• Fix wrong width (a bit wider) of the gapfill (noticeable with gap_fill_min_width) #4029
• Fix Missformatted URL if no additional GET Parameter has been supplied #3974
• Fix Changing connection length cause crash #4025
• Hack to fix a bug in arachne generator, creating lines going to the moon #4032

note: sorry, I pushed this release initially on the wrong label, so maybe some repo may have build the 59.4 instead of the 59.5

Late 2023 edition

the 2.7 version is not ready, so here is a new 2.5 version, that should work better than the previous one, as the new fill_angle_template setting (vector field) mess the previous one.
I'll probably do another 2.5 version in 2024, just with bugfixes and translation updates, to be able to have a stable one.

known issues

• changing infill connection length cause a crash. fixed in next nightly.
• problem with windows 11, you may want to remove the opengl32.dll from the mesa dir if you have problem with your graphic card, as a stop gap (this disable the 3D acceleration).
• still no mac build, will do that after 2.7 merge. For now, you can grab the mac-intel nightly from here, it's the same but without the translations.

New

• only one perimeter on top now also with arachne (thanks to orca, vovodroid).
• now the thumbnails header can omit the type, to adapt to creality firmware #3989
  • new setting: thumbnails_tag_format (bool)
  • old default is to have it deactivated for png (windows power tools only show the thubnails if it's png and no tag)
  • old default is to have it activated for all others (but creality wants jpg without tag)

Bugfixes

• fix modifiers #4016
• fix post process script #4016
• fix cooling slowdown (wasn't working) #4015
• fix monotonic ordering #3770
• fix travel acceleration #3821
• apply max_gcode_per_seconds for travels #3534
• gui: fix slider ticks #3975
• gui: fix missing "revert" buttons for filaments

Disappointing christmas edition

the 2.7 version is not ready, so here is a new 2.5 version, that should work better than the previous one, unless the new fill_angle_template setting (vector field) mess things up.

known issues

• new vector fields broke modifiers. they don't work in this version.
• problem with windows 11, you may want to remove the opengl32.dll from the mesa dir if you have problem with your graphic card, as a stop gap (this disable the 3D acceleration).
• still no mac build, will do that after 2.7 merge. For now, you can grab the mac-intel nightly from here, it's the same but without the translations.

New

• Allow some sorting of perimeters at gcode path planning, to get a bit better path planning (and maybe more issues).
• Add fill_angle_template and fill_angle_cross
  • fill_angle_template is a vector setting that allows you to setup the infill angles to use.
• Fan cooling: move min_fan_speed to printer. fan_always_on changed to a real default_fan_speed
• now default will be used when a field is deactivated.
• default_fan_speed =0 is a bit like the old fan_always_on to false.
• fan_printer_min_speed is now a real min for fan speed (if not stopped)

Bugfixes

• disable "seam notch" when spiral vase and also when no perimeters #3997
• allow scripted option to be disabled & searchable
• fix removing the whole line G1 Z. F.... if feedrate is same as before. #4004
• Fix Crash when adding custom printer #3977
• Don't crash if there is some empty lines in the ui layout.
• fix snug support with 0 bottom interface layers #4012
• fix preview for brim_per_object without complete_objects #3969
• wipe tower use filament_max_speed
• fix too many polygons exported in the gcode file #3798
