Grid:Apps Future Notes

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

Kiri:Moto

  • B origin (and bed size) bug (Onshape?) when switching device modes

  • B can't drag slider bar on ipad / ios -- touch pad scrolling dodgy

  • B prevent or ask for really large models when scaling (crash ui)

  • P duplicate objects should share same slice data unless rotated or scaled

  • P allow selection to be decimated on demand (context menu?)

  • P move all persisted / workspace settings/data to IndexedDB (LS limitations)

  • P do not move (average) endpoints connected to long lines in decimate

  • P explore widget vertex reloading / replacing (Onshape) (issue #48)

  • P faster ray intersect https://github.com/gkjohnson/three-mesh-bvh/

  • F edit in Mesh:Tool

  • F custom device vars for profiles / ranges / gcode

  • F show slider range values in workspace units (on hover?)

  • F allow select of a range by typing in values in slices or workspace units

  • F complete and expose grouping feature

  • F add svgnest-like arrange algorithm

  • F warn if part hanging in negative Z space or off bed in general

  • F date column and sorting in recent files list

  • C reflow device dialog to add bottom tabbing, vertical macro list

FDM

  • B fix support projection/end 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 add layer start position as a range option

  • F support pillar top/bottom should conform to part

  • F support pillar should have solid top/bottom

  • F more explicit line width control with ranges and min/max adaptive

  • F test outlining solid projected areas (internally)

  • 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 option to support interior bridges when 0% infill

  • F calculate filament use per extruder per print

  • F expand internal supporting flats / solids before projection

  • P reduce fan speed for bridging

  • P enable purge blocks when quick layers are detected

  • P refactor skirt, brim, raft as synth widget instead of in path routing

  • P extruder + filament max flow rate cap in planner

  • P revisit path routing / optimization

  • P solid fill the tops of supports for down facing flats

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 auto bed resizing leaves the origin in the wrong place at first

  • B re-add progress calls for all work units

  • F promote forced layer retraction to a range parameter

  • F test and enable arcs in belt more

  • F anchors should be generated anywhere needed in the print, not just head

  • F slightly angle supports to lean into the Z of the part

CAM

  • B tab cuts cause loss of direction, parenting, depth, and it's hard to fix

  • B tabs are not cut to exact height

  • B tabs do not properly track widget mirror events

  • B first rough step too far down in certain circumstances?

  • B need to force cut line at synthetic z bottom (midlines, etc)

  • B contour does not honor clip to stock

  • F add plunge max to contouring that can override z feed limit

  • F roughing flats should be constrained to flat region

  • F limit cut depth to flute length of selected tool (or warn)

  • F add ease-down support to trace op

  • F change color of line selection in trace op when not a closed poly

  • F add linear clearing strategy

  • F add adaptive clearing strategy

  • F user-defined origin (issue #28)

  • F intelligently turn circle hole pocket clear into spiral down

  • F trace follow hole that matches endmill should turn into a drill op

  • F add climb/conventional into each operation

  • F update analyzer to detect overhangs from faces, not slices

  • 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 to avoid jerk

  • F lead-in milling

  • 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 maintain several part orientations + op chains in a single profile

  • P port slicing to common core & refactor accordingly

  • P decrease cutting speed when entire tool is engaged (start of roughing)

  • P clear void should cut inside-to-out when a part would be freed from stock

  • P port arc code from FDM export to CAM export

  • 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 allow faster z movements when contouring (not plunging)

  • P common / faster shadow generator using vertices shared with ledges

SLA

  • P blit layers w/ 3JS ortho camera to canvas

Laser

OctoPrint plugin

  • subfolder parameter for dropped files
  • auto-kick check box in preferences

Mesh:Tool

  • send to Kiri:Moto workspace (or update model vertices in place)
  • face selection: find regions with < delta to normal
  • better z snap using just vertexes from face intersected
  • add section view. local clip. raycast skip points above plane
  • add isolate op = separate bodies
  • add decimate op = face reduction
  • add flatten/crush op: for z bottoms
  • allow setting model/group origin for scale/rotate
  • fix mirror to work with groups (just models currently)
  • bounding box toggle should be global, not selection
  • add analyze results dialog
  • rename analyze > patch
  • remove auto-repair function
