New in SuperSlicer 2.5 59.7 Pre-release (Feb 8, 2024)

  • 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

  • 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:
  • Fx 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)

  • 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

  • merged against PrusaSlicer 2.4.1
  • Remove aligned rectilinear, add tooltip tip for aligned setting, as there is no reason to only allow this one to be aligned.
  • Set default support_material_contact_distance_type to filament #2520
  • Check your support settings if your profile is using the default values!
  • MLocalization update:
  • now save TODO and all utility files for easier updating of localization
  • Changed the building script to not include .po files into the release, so download a nightly build or clone the repository to get them.
  • Parse the temp change from filament start custom gcode #2549
  • Allow m117 & M73 at the same time
  • Add "section" as a new color option. It's the mm3/mm. (useful to debug things, as heigth & width may not be related to it )

New in SuperSlicer 2.3.58.1 Beta (Mar 7, 2022)

  • new (gui):
  • scripted widget update:
  • scripted widgets now have the reset button
  • can use custom variables
  • can reset other widgets to last saved value. (and some other API improvements)
  • now used for
  • "overhangs" (in simple mode) : a quick on/off for overhangs like in PS
  • "seam type" (in simple & advanced mode, to avoid having to tune the weights: shortcut for corners & nearest)
  • "thick_bridge" (as a complicated example using custom variables).
  • "Wall thickness" to let the script handle the perimeter width.
  • quick settings (on/off brim, support selection)
  • image
  • Change mode (simple/advanced/expert) into tag
  • the quick buttons still select only one. But the menu time in configuration->mode allows selecting multiple ones.
  • there is no incentive in the current simple/expert version, but you can add your own tags & add tags to widgets via the UI files. There is an example within the UI layout variant.
  • This allows you to forbid a widget/setting on expert but not on Simple tag, so it can "move" between "mode".
  • Allow switching between multiple settings layout via preference menu
  • now, you can create your own version of the UI. If it's in its own directory with its own name (in the version.txt), it won't be erased when using a new version of the slicer.
  • It controls the tags, default colours, settings layout, scripts, quick settings.
  • I'll add some buttons & helpers to help with import/export & updates in the future.
  • put new tags & a new quick setting to a new "example" setting layout.
  • image
  • Small UI reorganization in simple & advanced
  • move Simple print settings to only 2 tabs (thanks to the tags)
  • a bit of shuffle in the preference, to avoid "big page" vs "almost empty page"
  • Added a blank space (on windows) before the settings tabs, to better separate them from the platter. It helps me a lot to click on the right tab. Tell me if it's too much or just awful.
  • When loading a file, allow bad value to be substituted.
  • add a file to ignore subsequent dll warning #2406 (wip)
  • new (other):
  • Add "bridge type" setting. A bit like the prusa "no thick bridges" but more powerful.
  • merged "QOI G-code thumbnail" from PrusaSlicer,
  • also added "biqu thumbnails", but I need some help to check if it works.
  • Fix raft flow problem & raft double sheath #2394 #2400
  • Now sheath infill is printed just after the perimeter sheath
  • remove support_material_solid_first_layer as there is no a % and there is always a sheath
  • M221 M220 implementation in gcode-viewer (note that the M221 has already some code but it seems ineffective.)
  • Update to gcode header (generated by) and parsing of them. #2388
  • update profiles (Prusa profiles use a modified version of the 2.4 version instead of a merge of the previous ones)
  • bugfixes:
  • fix windows crash at startup
  • fix color.ini malformed line (many many reports of corrupted settings)
  • Add debug log, warning message, and failsafe code for missing fill_pattern on some project files. #1983
  • now you should be able to open the borked project files.
  • the goal is still to fix the root issue, but I need the logs to get a little clue.
  • fix wizard
  • Fix perimeter artifact & brim resolution #2428
  • Fix modifier type
  • Fix deactivated first_layer_print_min and first_layer_print_max #2381

New in SuperSlicer 2.3.58.0 Beta 2.4 (Feb 14, 2022)

  • new:
  • Acceleration control (by @julianschill):
  • Also modified the speeds a bit to have the same functionalities
  • Also now deceleration should happen at a better point in the travel path:
  • if too short, it use the target accel for the whole travel
  • if short, it will switch to target accel at the tipping point
  • is the path is long enough, it will switch a bit before the needed distance to decelerate
  • "overlapping perimeters" now have thresholds
  • scripted widget (aka fake setting): Allow to create "simple settings" that modifies the real ones:

New in SuperSlicer 2.3.57.9 (Jan 5, 2022)

  • Changes:
  • 'retract only when crossing perimeters' now also consider top surfaces as external area, so it won't cross it without a retract.
  • Spiral vase: allow to choose the seam start position. #2114
  • Fixes:

  • fix filament override #2110
  • some tooltip changes, etc.

New in SuperSlicer 2.3.57.8 (Dec 23, 2021)

  • Changes:
  • Custom macro variables: two new keywords: 'exists' and 'default', to be able to fallback when using custom variables defined in filament & print settings.
  • 'default(var_name,value)' check if the variable exist and affect it the value if not.
  • The variable can be boolean 'true' 'false', int '0' '12', double '1.0' '42.24' or string '"a string"'.
  • 'exists(var_name)' return true if present. It also creates a dummy boolean variable if not already set.
  • Note that if you're using the variable in a formula, it may crash even if guarded by a {if} as everything is interpreted (no lazy check).
  • So be sure to add a 'default' so it gets the right type and the formula can be interpreted (unless you just print it, in this case an 'exists' is enough).
  • Using 'default' doesn't change the return value of 'exists'.
  • Add a new setting 'wipe_only_crossing' to diable/enable wipe when you're using 'avoid perimeter crossing'.
  • Fixes:
  • Fix 'avoid crossing perimeters' when wipe enabled.
  • When 'wipe on retract' on an external perimeter, continue to wipe inside the object instead of coming back to the middle of the perimeter.
  • profile update: Fix extrusion_spacing for Anycubic
  • Fix medial axis creating points on top of each other.
  • Some tooltip updates (thank you @blex-max for the help)
  • Updated ConfigManipulation (disabled/enabled) for width & spacing.
  • Fix 'merge thin walls with perimeter' (unneeded travels)
  • 0 extrusion_spacing will always create 0-auto-extrusion_width.
  • fix fan kickstart reverting when it shouldn't
  • Fix Concentric (Filled) infill: honour gap_fill_min_area
  • perimeter_round_corners: disabled for the first perimeter
  • fix div/0 in libnest2D

New in SuperSlicer 2.3.57.7 (Dec 12, 2021)

  • changes:
  • Dense infill: fix the full fill density bug & rework detection settings:
  • AutoNotFull: now print the dense infill only if the area to cover doesn't fill the sparse area.
  • AutoOrEnlarged: now print the auto dense infill, unless the area to cover is wider than (nozzle diameter*2/infill ratio) and the enlarged version is smaller than the auto
  • New: AutoOrDisable: now print the auto dense infill, unless the area to cover is wider than (nozzle diameter*2/infill ratio) or the area to cover fill the sparse area.
  • Bridge improvements:
  • Don't connect if too far away. Prevent printing a bridge over another one, following the perimeter.
  • Better connection direction, as both are now tested.
  • Fix some other rectilinear issues, crash, bugs #1889
  • Bridge detector now compute much quicker than in the previous version.
  • Fix wrong bridge offset (can lead to no bridge or some missing)
  • Fix too detailed gapfill:
  • Add resolution_internal to control it (and gyroid)
  • Disallow gapfill lines to be split in the middle when printed (now start at an end and not in the middle)

New in SuperSlicer 2.3.57.6 (Nov 18, 2021)

  • New:
  • Bridge_overlap fix & redesign (now bridge density)
  • Now has a min setting.
  • The density is now chosen between the two values to try to cover as much as possible the area to bridge, with the highest density possible.
  • Remove the hardcoded invisible 87.5% density modifier. Replaced by setting by default the max at 90% and min at 80%
  • Try to place the bridge at the right position (only works if the shape is simple).
  • Known issue: the algo used for bridging can add a return line on top of an already extruded line. Have to do something about that.
  • If you want to get back the old behaviour, set the two values to 87.5
  • Add total layer count in the gcode footer #1886
  • Add current_position variable for gcode macro: current_position[0] is x and current_position[1] is y #1898

  • Custom variables:
  • On each tab, you can add variables (under the note page) that will be available for custom gcode macros.
  • Be careful with the syntax. Don't hesitate to launch the slicer with logs (--loglevel=5) to be able to see what's parsed.

  • Trigger at retract_before_travel or when the travel is longer than 3 nozzle
  • Can trigger without only_retract_when_crossing_perimeters
  • travel can now slow down to avoid going out of the max_gcode_per_second
  • travel acceleration is now bound by machine_max_acceleration_travel and not machine_max_acceleration_extruding
  • Don't split travel for deceleration if there is no need for
  • Add lift_min: minimum height to travel between objects #1783 #1775 #1575 #599 #429 #395 #241:
  • At the first move don't split the travel #1560
  • At the first move, if start_gcode_manual and no layer_gcode, don't lift the nozzle so the printer won't "z-dance", whatever where the nozzle is.
  • retract_lift_first_layer is gone back to the old simple behavior (revert b16ecbf)
  • removed auto extra lift for first layer, now that lift_min exists.
  • with complete_object, don't unlift at object/first layer change, to avoid Z-dance
  • lift_min will be used between brims, skirts, objects but not between object-skirt, object-brim and their object

  • Ironing is also considered as a top for "lift only on top surfaces" #1773
  • Add an option to show alternative "custom tooltip", to bypass the time limit on some os. It's a half-assed solution, but at least you should be able to read them (tested on windows & linux) #1720 #1291
  • update build scripts: now there is an option for gtk3 & debug build in BuildLinux.sh
  • Updates to dense infill: #1657 #1671:
  • reduced unneeded usage of "full fill"
  • Don't allow holes in infill_dense
  • Print them in the correct order
  • Ensure that infill_every_layers and infill_only_where_needed are disabled, because it can't tolerate voids (they create different regions)
  • now multithreaded
  • Better bridge angle computation, and ready for tweaking weights (currently 70% coverage, 15% median length, 15% max length, 5% bonus for following a perimeter) #565 #234 #149
  • When removing too thin bridge, use it as solid instead of sparse.
  • Search: display tooltip in tooltip, search full sentence in tooltip (low score).
  • Preference for hiding settings lock&dot icons #1729

New in SuperSlicer 2.3.57.1 Pre-release (Oct 8, 2021)

  • New:
  • Add filament_max_overlap, to control the line spacing via filament setting
  • It allows controlling the spacing vs width, like the "perimeter overlap" but for everything. It allows reducing overextrusion with filament that don't flow well (high viscosity) and so can't go under the nearby extrusion to fill the voids.
  • For example, it may be better to use a ~35% overlap for abs.
  • Add 'only one perimeter on first layer' as doing it manually via modifier wreck solid bottom layer count #289 #584 #1566
  • Add seam_gap to control the space between the start and the end of the loop, for seam quality. #1534 #1606

New in SuperSlicer 2.3.57.0 Pre-release (Sep 8, 2021)

  • New settings:
  • Setting to remove unwanted bottom/top fill on slopes #253 #426 #1090
  • Image
  • 'complete_objects_one_brim' to print one big brim for the whole plater to be able to pack the object closer to each other.
  • Now takes into account per-object brim for auto-arrange & complete_object check
  • Setting to create the skirt's brim #795
  • Setting to decide from what the skirt is drawn (objects or brim) #747
  • Setting to decrease elephant foot compensation on multiple layers, from a pr by @bitblaster
  • Setting for infill/internal bridge fan speed #1414
  • Setting for wipe speed #1471
  • Setting to set a minimum first layer speed #1422
  • Setting to allow gapfill between the most inner perimeter if the gap is narrow enough #982
  • Setting to rotate polyholes on each each layer. #1396
  • Setting for travel acceleration
  • Now deceleration for the travel is done with the acceleration value of the next extrusion
  • Reprap M204 now use P & T
  • Setting to forbid some characters in the gcode filename #1518 (plain characters or regexp)
  • 'Max gcode command per second' added to replace the 'min_length' setting. To avoid stuttering in 16bit microcontrollers or serial interface bottleneck.
  • Gui changes:
  • G2 & G3 gcode-viewer support (ArcWelder) #1456
  • Reworked autospeed & ironing role:
  • Now only extrusions with a "0" are taken into account for autospeed computation

  • Ironing_speed is now a float or percent, over top_solid_infill_speed
  • Adding sections to general preference.
  • Improved progress message (when creating perimeters, infill and gcode, so you can have an idea of how long it will take)
  • Add a GUI Preference option (Default: yes) to show the overwrite dialog for regular file output or not. By @lordofhyphens
  • Don't refresh the 3D view unless really necessary (should reduce memory consumption & increase responsiveness when the slicing is finished)
  • Other changes:
  • GCode double->string conversion improvement (remove trailing zeros) for reducing gcode size
  • Settings directory is now taken from a "configuration" directory if it exists next to the "resources" one (Allow of a "portable version" without the --datadir needed) #1212

New in SuperSlicer 2.3.56.0 Pre-release (May 23, 2021)

  • New:
  • Now you can set the spacing between extrusion lines.
  • There are two ways of deciding the 'width' of an extrusion line: by width or by spacing. One is set, and the other is computed over the other. The computed one has its label grey.
  • Set one will update the other one, taken into account the current layer height.
  • If you're using variable layer height, it's the (computed) width that is used, so the spacing will be different: bigger on big layer, and thinner on thin layers.
  • You have a little help image below (the help collapsible thingy) to explain the difference between width and spacing.
  • Add icons on tabs (can be disabled/resized in preferences)
  • Added a fourth option in the gui layout option : tab
  • Allow going back to sliced preview without the trick of modifying a printer setting.
  • All tabs are on the same bar instead of splitting them between the top bar and the bottom.
  • As it's a bit hacky (the panel has to be moved between tabs), some linux distribution may have some quirks with this option.
  • Vendor profiles have been moved to slic3r/slic3r-profiles. You have to git submodule update if you clone this repo.
  • Add start_gcode_manual to disable automatic 'start gcode' output #875 (in the Custom G-code tab). Note that it won't print anything, you have to ensure that you write everything needed in your Start Gcode section.
  • Update localization tools, now written in python and takes into account the ui_layout ini files.
  • Allow to choose the splashscreen. Can be random.
  • Update VORON cube to current version. Thanks to Benoit Miller
  • Out-of-bounds objects RED instead of blue. Thanks to Pavulon87
  • Add export to prusa menu item (so you're not limited to the .3mf that is already compatible)
  • Gui colors are now modifiable in preferences
  • Default gui colors are in colors.ini
  • Implement option from old Slic3r mainline to permit printer firmware to define their fan speeds from 0-100 instead of 0-255. Thanks to Joseph Lenox
  • 949 Consolidate what is a "project": The project is the current .3mf (even if not saved/named yet, it start with an empty one)
  • Ask for saving the project if unsaved changes
  • Ask for preset reset if new project
  • Delete all : new project or just delete
  • Need some more works, as there may still exist some incoherencies
  • Bugfixes:
  • Fix firmware min_length (may be the cause of some unwanted model simplification)
  • Revert "only one perimeter on top" to october algorithm.
  • If some letters on top of a flat surface create problems, set min_width_top_surface to 0 (on this layer only if needed).
  • Allow to have no prusa profiles.
  • Write some initialisation lines at the right line #1121
  • Fix fan speed on overhangs #1127

  • Note: projects saved with this version will transfer only prusa settings back to older superslicer version.
  • update it translation thanks to @boromyr
  • Fill "connect" update: now when using "0" as the max connect distance, the 2.2 algorithm is used (it won't try to create a perimeter, it just connect the lines). It's the default, so if you want to try out the new "connect" from prusa, you have to change it to 1000 as in prusaslicer.
