Mesh filtering edition

merged against slic3rPE1.42.0-alpha7

new

• new tab & icon for the setting, some option have changed place.
• Curve smoothing (slicing tab): an experimental option to try to smooth curve by applying a Bezier curve where a point has a specific angle against the neighbours. These point are the intersection of the polygons's edges and the slicing plane. This may allow you to export a rough cylinder and print an extremely smooth one. Be careful, as it only work on layers, don't use a low angle threshold (160 max is recommended). Will do a wiki on that later.
• Model rounding precision (slicing tab): Now, slic3r remove colinear points, to simplify the input geometry by removing points/edges that are on a middle of a plane (so they are useless). The setting allow some deviation from the plane. So a plane that should be flat but isn't because of the rounding precision of the stl file, now can be flat again.
• skirt & brim are no per-object when you select "compete individual object" #48 bugfix in next version
• no perimeter on bridge area: reworked
  • Remove perimeters: remove the unsupported perimeter, let the bridge area as-is."
  • Keep only bridges: remove the unsupported perimeter, kep only bridges that end in solid area."
  • Keep bridges and overhangs: remove the unsupported perimeter, keep only bridges that end in solid area, fill the rest with overhang perimeters+bridges."
  • Fill the voids with bridges: remove the unsupported perimeter, draw bridges over the whole hole. !! can lead to problems with overhangs shape like /\, consider carefully before using this option!"

##bugfix

• #52 #47 #48 #45
• gyroid & 3d honeycomb now doesn't produce incoherent connecting lines anymore.
• gyroid & 3d honeycomb have more connected line, it's not perfect yet (wip)
• now the settings have a better label when selected in the contextual / right menu.

notes

I may add here a bugfix-only 1.42.0-alpha5.3 in some days

Early fan edition

note : prusa3d hasn't released their alpha6 yet, so it's not merged inside that one. But it's merged over their alpha6 tag (i don't think it will be used).

new

• solid fill pattern setting, to change the pattern of the solid fill. Should be kept at rectilinear, but feel free to experiment with it.
• rectilinear infill : now a bit better handling at connection in sharp region (try to fill the empty bits a bit more, can connect more often). I had some under-extrusion in these area, i hope i don't overshoot with these changes.
• add "filament max wipe tower speed" (filament ->advanced)
• add a bit more option to filament type, go here to see how to use them
• support : new setting to select the interface fill pattern .
• experimental sawtooth fill (idea from e3d). But i didn't test it yet, so be careful, it will print as shit.
• fan startup delay (hardware->general->firmware) to start the part cooling fan a bit earlier if possible. It doesn't jump over the previous object, so it shouldn't wreck the cooling. It can add a new option on the M106 to tell the firmware that the fan should be at this speed in X ms (no firmware support that yet).

bugfixes

• all from 1.42.0-alpha5.2
• better role for gapfill from concentric fill.

[more stable] Boring edition : bugfixes v2

From now, i'll try to have a branch with only bugfixes (stable branch), and an other with new experimental stuff that can broke everything.

fix vase mode
fix too thin bridges
fix some thin walls bugs (not connected correctly, wrong path fusion)

Boring edition ++

bugfix

• extra perimeters now work again
• an extra check for vase mode
• better end gcode for "basic printer" config (via wizard)

Boring edition

new

• width % is now in function of nozzle diameter instead of layer height.
• add "taper" at the begin/end of thin walls when <100% (may help to print better)
• add setting to set the overlap between thin walls and perimeters.

bugfix

• remove some unwanted gapfill
• bugfix ironing #37
• bugfix solid margin #36
• bugfix thin wall width (not exactly the right size)
• bugfix on the connected lines of gyroid infill
• bugfix dense infill ctd

** issues

• seems like vase mode isn't working correctly, i didn't had the time to check yet.

1.42-alpha4.0 : auto purge block.

new

• purge block volume now can be automatically computed. You have to set the "filament pigment" setting (how hard it is to clear the nozzle) and the different settings in ""hardware settings" -> single extruder mm setup" -> "advanced wipe". The purge block values are printed on the terminal. #30

bug fix

• #24 #31 #32 #33

issues

• overlap & ironing are broken. Will be fixed in the next release.

1.42.0-alpha3.1 : support edition

new

• Contact z-distance: now split in 3 parameters: on can choose if you want to count from the filament, the "plane" or use a soluble filament. And there are a separate parameter for the top & the bottom
• gyroid & 3Dhoneycomb: now the connected lines follow the perimeters (it can slow down the slicing process a fair amount, check "do not connect line" to deactivate).
• scattered rectilinear infill from Nicholas Sherlock (@thenickdude) : to not be able to see the infill by transparency (need some reviews to see how it impact the top layers).

#fix

• infill connected lines : now work also for "lines"

brim ears edition

new

• merge with slic3rPE 1.42-alpha3
• setting to transform the brim in ears: an ear in draw on sharp corners (can be defined in the brim ears angle setting)

not-the-same-settings-directory edition

new

• build against the slic3rPE-alpha2 release (working datadir option)
• use by default the slic3r++ directory instead of slic3rPE for storing the settings.
• add an exemple of a bat script for using the --datadir option

2019 New year edition

new

• build against the prusa 1.42.0-alpha : new gui, no more perl. See the prusa release note for all the changes
• new parameter for thin walls: the minimum thickness to takes into account
• new behaviour for thin walls: now, each thin extrusion with a thickness less than the nozzle diameter will be increased to the nozzle diameter, because it's the only way to extrude something good enough.
• option for "no z-lift" for top solid layers (in nozzle setting tab)
• switch to 64bits for the compiled release.

fix

• fix the skirt bug from the previous version.
• reverse the behaviour of "hole XY compensation" to be more in line with the two other fields: negative to increase the size of the hole / reduce the size of the part over the hole (I promise to not change it again).
• fix the "dense layer" option that was a bit bugged.
