# Kiri:Moto todo

## 2.3 remaining

## 2.4 tenative list
* cnc
*   tracing (chamfer, engrave)
*   milling visualization
*   auto feature detection (slicing), manual tabs
*   add tabs to shadow and slice model (for topo)
*   step down should interpolate top/bottom again
*   adaptive shadow-line generation for small parts collision detection
* fdm
*   manual supports
*   continuous printing (z belt systems)
* laser
*   drag knife support
* onshape
*   session token timeout bug
* all
*   2d image to 3d part
*   circular fit/layout when no-layout to prevent collisions

## `C` cosmetic, `F` functional, `P` performance, `B` bug fix

* `F` 2D image import
* `F` detect and report slow framerates
* `F` implement an in-app bug reporting system. add workspace to export option.
* `P` improve decimation speed by avoiding in/out of Point?
* `P` duplicate objects should share same slice data unless rotated or scaled
* `P` worker state cache cleanup and organization
* `P` client/worker interface normalization and cleanup
* `C` improve path line caps

# FDM

* `B` fix adaptive slicing. also with multi-extruder
* `B` fix supports with grouped parts
* `B` infill follows inside shells
* `F` speculative background preview generation
* `F` control for size of purge block (with 0=disabled)
* `F` add separate fill speed control
* `F` manual support addition / control
* `F` control layer start position
* `F` polishing and other non-planar work
* `F` gradient infill https://www.youtube.com/watch?v=hq53gsYREHU&feature=emb_logo
* `F` feather sharp tips by reducing extrusion in area of overlap
* `F` first layer segment large flat areas for better fill reliability
* `F` enable purge block when quick layers are detected
* `F` apply finish speed to exposed top and underside flat areas
* `F` expand internal supporting flats
* `F` first layer support speed should be same as shell speed
* `F` determine start point from gcode preamble
* `F` trim support offset from layer below
* `F` option to support interior bridges when 0% infill
* `F` calculate filament use per extruder per print
* `P` segment large polygons for extremely large parts / infill
* `P` implement infill clipping in wasm

# SLA

* `P` prioritize supports by length of unsupported span. mandatory when circularity > X
*     or % area of inner to outer poly is high (making it a thin shell)

# CAM

* `B` outside cutting direction in roughing mode inverted
* `B` clear voids has double interior pass because wrong offset shadow used
* `B` fix contour up and over thru holes by adding (union) tabs to shadow
* `F` adaptive shadow-line generation for small parts collision detection
* `F` flat and volumetric rendering of paths
* `F` z bounded slices (extension of z bottom offset feature)
* `F` z planar settings visualizations
* `F` use arcs to connect acute angles
* `F` extend acute roughing on inside polys to clear small voids
* `F` lead-in milling
* `F` adaptive clearing in roughing mode
* `F` trapezoidal tabs (in the Z axis)
* `F` ease-in and ease-out especially on tab cut-out start/stop
* `F` implement z line-only follows for ball/taper
* `F` add option to spiral in vs out (optimal tool life) vs mixed (optimal path)
* `F` add endmill spiral direction to fully respect climb vs conventional
* `F` add support for tapered ball mills
* `F` warn when part > stock or cuts go outside bed
* `P` crossing open space check point is outside camshell before returning max z

# Laser

* `F` overcuts, radii for drag knives
* `F` add PLT / HP-GL output format (https://en.wikipedia.org/wiki/HP-GL)
