No more unwanted infill, on slopes

Note: The stable version is the 2.3.56.9, below.

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
• Some gapfill / thin wall optimisation, should compute perimeters ~5-10% more quickly.
• Move Extruder decimals from extruder to printer #1596
• Emit error if max layer height > nozzle diameter

bugfixes

• Fix error when scrolling over a layer with feature selection: everything was filtered out. #1522
• Fix artifacts from the "no more unwanted infill" (nb_perimeter_layers_for_solid_fill) feature #1581
• Fix lack of refresh after gcode generation #1533 #1591 #1532 #1542
• Polyholes now don't recognize a rectangle as a badly made circle to polyhole-ize. #1561
• Fix weird interior brim when inside an hole (inside island) #1526
• Fix retract_restart_extra_toolchange, now trigger at each first tool unretraction (but the very first) #1052
• fix small tab icon #1605
• Fix bridge_internal_fan_speed when equal or lower than the default speed #1414
• Fix the XY hole compensation when no threshold set #1540
• Fix Disabled acceleration control still applies to print #1537
• Fix some UI size issue on mac & linux: Add label_left option for setting ui to print the label aligned to the left instead of the right #1573
• Fix some gapfill issues (bits on the outer edge of a curves)
• Fix seams positions when each object has its own layers
• Fix "ensure vertical shell wall" for spiral vase #1582
• allow retract_lift_first_layer even when 0 lift to activate extra lift for first move before each object on first layer #1575
• Fix 'auto' max layer height #1569
• Fix first_layer_size_compensation #1547
• Fix undo/redo issues
• increased precision for overhang detection #1562
• Fix no_perimeter_unsupported_algo when there is multiple bridge areas #1595
  • Also Now "no perimeter on bridges" -> "only bridges" follow bridged_infill_margin #1155
• Increase detected bridge area a bit to tame it a bit the extra perimeters on overhang #1514
• Fix wrong boundingbox that mess with the support tower height #1612
• Fix Bridge flow calibration text with first layer height of 0.3 for a 0.4 nozzle #1462
• Fix color update on fresh extruder (it prevented to add an extruder switch)
• Increase max possible wipe speed to 400 (#1568) by Dave Bullock
• some typo & setting names

No more unwanted infill edition

Merged with PrusaSlicer 2.3.3

Note: The stable version is the 2.3.56.9, below.

new settings

• Setting to remove unwanted bottom/top fill on slopes #253 #426 #1090
  
• '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 type with a "0" speed are taken into account for autospeed computation
  • ironing pattern now use ironing role like ironing PP
  • 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) edit: it doesn't refresh often enough, even when necessary

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 to create a "portable version" without the --datadir command line option) #1212
• layer height & first layer height light update
  • test if the values are good before slicing.
  • first layer height with % now use the (thinnest) extruder used by the object
  • fix skirts when using different nozzle diameters (print it wide enough for the biggest if %)
• allow to --load a config bundle with command line #1490
  • it won't save it, contrary to the "import config bundle"
  • If the config bundle only contains the [presets] section, it will just try to select the presets.
• sequential printing: Disable clearance check if set to 0
• updates to russian & french translations

bugfixes

• fix icon for sla
• fix some perimeter & infill slicing issues
• remove hysteresis for overhang detection #1464
• fix error when changing the type of seam position #1485
• fix some errors in Layouts #1480
• fix export_to_prusa for object & modifer settings that need the full config as reference #1503

• updated french & italian translation

bugfixes

• shortcuts (mainly on macos)
  • now shouldn't prevent you from typing in fields

• float precision in gui fields is now available (if you want to only display 2 digit after 0 in some fields, it's possible)
• fix some regression in 'export to prusa' and compile errors
• fix un-savable "reprapfirmware".
  • because before, there was only reprap
  • I split it into reprap and sprinter
  • prusa split it into reprapfirmware and reprap
  • So superslicer Firmware key "reprap" is now "reprapfirmware".
  • When a config file contains "reprap", Susie will consider that it means "sprinter"
• calibration: editable fields are now correctly read.
