# Kiri:Moto todo and notes
## `C` cosmetic, `F` functional, `P` performance, `B` bug fix
* `B` normals possibly inverted on faces in 2D to 3D conversion
* `B` normalize left, bottom, right pop menu time/click and value persistence
* `P` duplicate objects should share same slice data unless rotated or scaled
* `P` allow selection to me decimated on demand (context menu?)
* `P` improve decimation speed: omit point conversion or use wasm
* `P` client/worker interface normalization
# FDM
* `B` first rough step too far down in certain circumstances
* `B` fix adaptive slicing with multi-extruder
* `B` fix supports with grouped parts
* `B` multi-extruder rendering of raft fails to offset the rest of the print
* `B` multi-extruder purge blocks fail to generate properly for rafts
* `F` slicing controls per user-defined z-region
* `F` control for size of purge block (with 0=disabled)
* `F` add separate fill speed control
* `F` polishing and other non-planar work
* `F` gradient infill https://www.youtube.com/watch?v=hq53gsYREHU&feature=emb_logo
* `F` first layer segment large flat areas for better fill reliability
* `F` feather sharp tips by reducing extrusion in area of overlap
* `F` enable purge blocks when quick layers are detected
* `F` option to support interior bridges when 0% infill
* `F` trim support offset from layer below
* `F` calculate filament use per extruder per print
* `F` first layer support speed should be same as shell speed
* `F` apply finish speed to exposed top and underside flat areas
* `F` expand internal supporting flats / solids before projection
* `P` implement infill clipping in wasm
* `P` solid fill the tops of supports for down facing flats
* `P` sparse infill should follow polys between intersect points
# FDM - SLA
# `P` common support area detection (fork new fdm code)
* `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)
# FDM - BELT
* `B` fix supports for belt printing
* `F` hide layer lines under print
# CAM
* `B` clicking on a pop-op should pin it until clicked or [esc]
* `B` need to force cut line at synthetic z bottom (midlines, etc)
* `B` non-clear-voids duplicates thru-holes
* `B` z thru doesn't respect step down
* `B` failure to go *up* when moving between parts?
* `B` starting export during animation unleashes chaos
* `B` climb vs conventional not fully consistent after refactor
* `B` outside cutting direction in roughing mode inverted
* `F` new registration style: offset cutout
* `F` add climb/conventional into each operation
* `F` z thru should apply to any thru hole
* `F` update analyzer to detect overhangs
* `F` add linear clearing strategy option for roughing / pocket
* `F` extend acute roughing on inside polys to clear small voids
* `F` option to use part / STL coordinate space to determine X,Y origin
* `F` validate muti-part layout and spacing exceeds largest outside tool diameter
* `F` polygon simplification option in tracing (for image derived maps)
* `F` parameterize dropping close points in prep.js. ensure long segments remain straight
* `F` flat and volumetric rendering of paths
* `F` z planar settings visualizations
* `F` convert acute angles to arcs
* `F` lead-in milling
* `F` adaptive clearing in roughing mode
* `F` trapezoidal tabs in Z
* `F` ease-in and ease-out especially on tab cut-out start/stop
* `F` add option to spiral in vs out (optimal tool life) vs mixed (optimal path)
* `F` add support for tapered ball mills
* `F` can animation clear the mesh in areas where the cuts go through the stock?
* `F` support lathe mode / A-axis / rotary
* `F` gcode output option as zip for multiple or flip ops or tool change
* `F` ease-down should be engaged in all descending cutting operations
* `F` new reg type based on https://youtu.be/BLD4dFoXC7o?t=360
* `P` common part pre-analyze to speed up 'slice' and improve shadow (overhangs)
* `P` redo all path route / planning in prepare to account for terrain before camOut
* `P` detect render message backlog and pause or warn
* `P` allow faster z movements when contouring (not plunging)
# Laser
* `F` add PLT / HP-GL output format (https://en.wikipedia.org/wiki/HP-GL)
