Spacing edition

This branch may turn into the stable one. I just want to iron out the last bugs with a beta before.

There is still some problems on the code generation (mainly for multi-extruders printers), but these will be taken care on the next version.

known issues

• windows: delete the opengl32.dll to get back normal performance.
• windows: translations are borked (unless you use the uft-8 mode)
• I again made an error when naming the zip ><

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
• fix loading prusa conf
• fix polyhole algo
  • add a hole_to_polyhole_threshold to allow a user-defined margin (because not all circles are perfect) #924
  • do not considerate ngons as circle if n<9
• Fix deadlock when canceling the slicing while creating thumbnails
• Fix clipper::union adding extremely small holes even with safety_offset
• fix anchor_length > anchor_length_max error

• Fix for auto-heating when using one extruder from many #1103
• #1083 Make deselectable the automatic switch from tabs during background processing
• #1076 adjust color changes for z_offset

Super brim ears

It's merged with the prusaslicer2.3.0

note that it won't work on macos 11

new

• Brim ear update
  • add brim_ears_detection_length to be able to detect "sharp rounded angles"

Export to PS edition

It's merged with the prusaslicer2.3-alpha4

new

• Export to prusa:
  • now the .3mf prohect file contains the modified config compatible with purusaslicer
  • now the superslicer settings are stored in their own file.
  • 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.

bugfixes

• #693 fix crash when using fan kickstart without fan startup time
• #697 fix Random seam position when only one perimeter.
• #699 fix remember last folder for opened file
• fix the new arrange from prusa: now takes "complete objects" into account
• fix a crash while deleting items too quickly for the gui.
• #680 fix post-process ironing "Topmost surface only"
• fix ironing on support material interface
• some fixes on setting layout

[alpha] slimfast edition

The current stable release is the 2.2.53.4

new

• you can now name your extruder (only used in klipper for toolchange)
• #663 add ru translation thanks to @VectorPort
• I now update the .pot at the same time the version is updated, so you can use the one packaged in the software, so you won't need to compile it yourself for updating the translation.
• update linux doc for raspberry pi (to test/review)
• change icons to blue

bugfix

• now the "check for application updates" works again and will link the correct website
• now settings will be printed as previously in the end of the gcode (from the hotfix)
• fix crash when exiting if you have changed the extruder count (from the hotfix)
• fix physical printer dialog (from the hotfix)
• fields can again span the entire width (pushed to prusaslicer)
• fix windows dll load: now use the SuperSlicer.dll instead of slic3r.dll (prevent a naming problem with the macos build)
• #659 fix fan mover that has problem when the printer was without relative extrusion
• #658 fix position of "points" widget
• fix layer time color
• fix color print preview
• update to freecad: don't save temp path, call arrange if >1
• #661 fix support overhangs
• #651 fix holes in small pillars that were are wrongly filled (boost::voronoi weird bug)
• #305 fix brim height (bug when the first layer height was a %)
• #673, now klipper TURN_OFF_HEATERS is equivalent to M104 S0 for the gcode viewer

• #439 add support layer time to next object layer time if unsynchronized (but it seems to not work as well as intended)
• #614 allow acceleration to be a % of default acceleration ; also default acceleration can be a % of the max extruding acceleration
• #612 add soft threshold for big holes XY compensation
• change most of icon colors from orange to blue
