Hello

This slic3r fork is made on top of slic3rPE, but it has nothing to do with prusa, it's a personal fork for my use. Don't blame them if something don't work, it's my fault. It contains all features of slic3rPE and add some new options and bugfixes. These may be merged back into slic3rPE (and/or main slic3r) in the future, if they wanted it and have the time to do so.

Changelog:

infill:

• gyroid infill (now merged inside slic3r and slic3rPE)
• better connected lines for gyroid infill (& 3D honeycomb)
• ironing infill
• concentric + gapfill infill (don't leave gaps, like the perimeters)
• rectilinear + gapfill infill (better coverage where there are small surfaces)
• scattered rectilinear infill (random infill) (by @thenickdude)
• do not connect lines of infill
• denser infill below the first solid (top) layer
• ensure all solid infill extrude just the volume of plastic needed (not 99% or 101% but 100%)
• over-bridge flow compensation : allow to over-extutrude the layer over a bridge to catch the good z-height.

perimeters:

• extra perimeters if needed : add perimeter to not have infill over overhangs
• option to not have perimeters on bridge area, to be able to print counter-bore holes.
• only one perimeter on top area
• loop the perimeters to create one big loop.
• new option for seam ( 'nearest', moved the old 'nearest' to 'hidden')
• better thin walls (with an option for the 'min size' threshold)

support:

• can transform the first layer of the raft to a solid layer (support are printed over a 1-layer raft)
• split the z gap:
• • now you can select the z-gap mode: soluble filament (no z-distance), calculate from the filament, calculate based on the layer position.
• • bottom z-gap (part => support)
• • top z-gap (support => part)

advanced & others:

• brim ears (print brim-ears around corners)
• you can now set the size of the anchor the solid layers & bridge layer are grow of.
• xy hole compensation (only for convex holes)
• export part begin /end to be compatible with cancelobject (octoprint plugin) (now merged inside slic3r and slic3rPE)
• remove co-linear points ()
• XY curve smoothing
• brim & skirt are printed per object instance if "complete individual object"

filament:

• fans speed for top infill
• max speed for wipe tower
• auto-sized wipe tower based on filament pigment.

hardware:

• option for "no lift for top solid infill"
• "fan delay" to start the part cooling fan a bit earlier to take into account the time it needs to start.

fix:
