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

notes

I haven't tested the linux & macos build.
The mac arm isn't built anymore (until I find the will to reinstall & reconfigure the VM again).
The mac intel version will ask you for permission. You may need to do xattr -cr /Applications/SuperSlicer.app.

sept 2023

I left my job, so I can now concentrate to develop this software full time.
here it's a collection of pull request and bugfixes from the last version, before i merge with prusaslicer2.7

New

• Add 'external perimeter seam gap' (seam_gap_external) to be able to add a hole but only on the external perimeter, to print gears on bad printers. may work better than seam_notch, or maybe with both.
• Better concentric infill with gapfill
• Semi-parallel printing by @vova #3445
• Add a speed knob to the wipe tower. by @amforpeace #3569
• Add max layer height to adaptive layers by @vovodroid
• Width change on odd layers by @vovodroid #3688
• Add option to avoid z lift for short travels by Julian Schill #3695
• Show layer time by @vova
  • you can choose in preferences what to show in the slider.
• Rework of fan speed control by extrusion type. Thanks to @legend069 to have started this, with its pr. #3735 #3608 #3568 #3415 #3408 #3380 #3367 #3361 #3271 #3152 #2872 #2696 #2419 #2326

Arc fitting edition

Merge with prusa 2.5, also integrated the G2/G3 interpolation from bambustudio.
Still a beta, I didn't have much time to debug it. I used it last week on my computer for some prints.

Sorry for the long hiatus. I had to take a break from macos signing & compiling issues.
There is a huge amount of issues to review, and it will take some time to review them all. I'll try to find & fix the most serious bug first.

Last month, I was working on data synchronization (for profiles). Ten of thousand code lines, and it's far from finished.
I'll also work on the 2.6 merge this month.
At the end of the march, I have a kind of "BootCamp" to work on treadmill printers and other things. So another version should appear in early april.

#known bug

• overhangs are broken.

#new

• Merge bambu studio G2/G3 gcode output (arc_fitting)
  • the option is in printer->general.
  • you can adjust the tolerance, useful for curves with low polygon count.
  • Note that it works best with high resolution (including brim & skirt)
• new seam placement from prusa 2.5: now send rays to find the less visible spots.
  • can be deactivated (it's a bit costly in CPU)
  • now there is contiguous & aligned. Aligned group seams for at least 6 layers, and can "jump" if a much better spot is found. Contiguous stay on the spot from the base plate (or enforcer).
  • now there is random and scattered. Scattered is like random, but only for external perimeters.
• add 'enforce overhang speed'
• experimental 'seam notch', but from my tests, it doesn't do anything good. So I may remove it.
• updates on profiles

merged pull request:

• Add Klipper-flavor EXCLUDE_OBJECT support #3208 by Frank Tackitt
• Round and show layer height by Vova

Arachne edition

Mostly the 2.4.58.4 with arachne and some support stuff.
Will also add the new seams from prusa, and maybe the support tree & G2/G3 from bambu.

know bug

• crash may appear when slicing multiple objects. (fix in nightly build)

Changes

• Arachne perimeter generation from PrusaSlicer, from Cura, based on a paper by Tim Kuipers. It creates variable extrusion width perimeters, to avoid gapfill.
  • It won't have many of the customization available for perimeters, as everything needs to be re-implemented from scratch. Currently, the fuzzy skin and the overhangs are done. The one-loop perimeter may follow, but it's harder as arachne doesn't create only loops.
  • Still some issues. It currently can extrude too thin, and still have some quirks, like wiping on the wrong side.
    
• Support & raft new settings:
  • raft_layer_height: layer height of the raft after the first layer and before the interface.
  • raft_interface_layer_height: layer height for interface on the raft. There is now as many interface as set for top interface.
  • support_material_layer_height: base layer height for support. May be decreased a bit by the algorithm to fill the support area as best as possible
  • support_material_interface_layer_height: base layer height for support interface. May vary a bit to be able to stop at the right Z.
  • support_material_interface_angle: angle to print the supports
  • support_material_interface_angle_increment: like the infill.
  • support_material_angle_height: add 90° to the support angle each time it moves by this height.
• gapfill new settings:
  • min_width and max_width: will remove the parts that are out of bounds. 0 fr auto
  • gap_fill_extension: increase the length of the gapfill by stretching it.
  • gap_fill_min_length: will remove the extrusion is too short
• Supports layer height now try to respect the z_step a bit more.
• Add physical printer settings as env variables for post-process scripts #2282
• Post-process script execution: now add python/perl before a .py or a .pl file. #2925
  • If the file can't be found, it tries again by adding the path of the superslicer directory before.
  • If the file can't be found again, it tries again by adding the path of the superslicer configuration directory before.
  • If the file can't be found again, it tries again by adding the path of the user directory.
• Also relative path if possible for Post-process script & texture & model paths. #1875
• Rework BackgroundSlicingProcess to support different SLA archivers. by Adam Elnagger
• Added password field for use with client certs By Pieter
• Setting for Bridging Pattern + Connection Control #2997 by Brandon Nance
• Vase mode: now the number of perimeters isn't enforced to 1 for the bottom layers. It is override to 1 for the vase layers.

bugfixes

• Now don't create a sem gap too wide for a very small extrusion (not more than a quarter of the length)

notes

I haven't tested the linux & macos build (but the arm one a little).
For the mac build, there is now an universal dmg. You shouldn't need to install anything, and you shouldn't need to bypass any security check (just a little "it's coming from internet"). If something is wrong, please open an issue so it can be fixed.
The mac intel version will ask you for permission. You may need to do xattr -cr /Applications/SuperSlicer.app.
The mac arm should run ok (was intended as a universal build, but seems to not run on intel hardware), tell me if there is a problem with this one.

note: I haven't tested the linux & macos build.
For the macos-arm, you need to install it and then use xattr -cr /Applications/SuperSlicer.app. And the arm compile is still a bit buggy, creating some nan/inf somewhere.

Custom ui edition

This is a beta version, not a stable one. Bugs are expected. The 2.3.57.11 is the current stable.

Merged against prusaslicer 2.4.1-alpha3

known issues

• Custom printers with a custom texture have a little 3D render issue that draws the bed grid on top of the object.
• Gcode is simplified with a "resolution" of 0.0125.
• dark mode preference checkbox is buggy. See #2485 to get a stop-gap fix.
• may crash on the first start. stop-gap: create the configuration directory by launching a previous version.

These bugs should be fixed on the nightly (Actions menu)

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)
      
• 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.
    
• 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
• Fix preview tab switching #2383
• Fix refresh gcode preview if already on it when gcode is computed. #2385
• Fix gcode preview color for temperature & layer time #2432
• Update info panel when modifying an object in the manipulation panel #2426
• Fix standalone gcode-viewer
• Fix d0ed35: datadir parameter kept when launching new instance. Now also on linux & macos #1450
• fix alignedrectilinear
• missing slicing_mode
• Fix host type mess in physical printer settings #2395
• Fix only cancel button on linux (bad merge) #2347
• typos (thx to Luca Simonetto)

note: I haven't tested the linux & macos build.
For the macos-arm, I still can't build it right now. I may be able to get my hands on a mac-arm laptop soon.
