nc_tools

A collection of composable CNC/CAM GCode tools.

$ cat robot2.ngc | nc_backplot

Implemented utilities

nc_backplot
- display a backplot of the incoming gcode
nc_model
- generate a 3d model of the incoming gcode, given tools and stock
nc_rename_axis
- rename an axis, a=> is delete, a=>b is rename, a<=>b is swap
nc_bounds
- bounding box of gcode or .off model
nc_transform
- transform / rotate stock for next operation
- nc_transform -a 45 -b 45 -x -30 # rotate 45 deg around x, 45 around y, translate -30 on x
nc_tooltable
- generate linuxcnc tool table from nc_tools.conf
nc_contour_pocket
- Generate contour parallel toolpath from gcode path
nc_stock
- Generate .off stock models
nc_svgpath
- SVG path data -> gcode converter
nc_identity
- gcode identity transformation - base for new tools
nc_arcfit
- recover G2/G3 arcs from linear paths
nc_delay
- delay the output of the gcode based on the machining time option 1x 2x, etc
nc_shortlines
- split incoming gcode into short line segments
- ~~cli option --arc-only~~
nc_slice
- Segments a 3d model into 2d slices for further processing
nc_contour_drill
- Generate a drill pattern bounded by the input gcode path
nc_contour_offset
- Generate contour parallel offsets from gcode path
nc_linear_ramp
- Convert plunge into linear ramp along path

~~not implemented / not complete~~

~~nc_fold_moves~~
- fold adajacent G00 moves
~~nc_pick~~
- nc_stop --at-comment blah --at-line 205 --at-tool 3
- selectively pick gcode from file
- e.g. within bounding box
~~nc_inspect~~
- allow playback of the gcode
- feed rate override + pause
- seek forward and backward
- zoom to section of timeline
~~nc_scale~~
- scale gcode axes up or down
~~nc_offset_rotational_origin~~
- translate to/from tool local (canonical) rotations to world rotation (e.g. rotary tables)
~~nc_feedrate~~
- analyse / optimise feedrate of provided gcode
~~nc_lathe_roughing~~
- G70/G71 canned cycle style lathe roughing generator
~~nc_blueprint~~
- Generate SVG blueprint with 3 ortho + perspective view of gcode / model.
~~nc_annotate~~
- Analyses and adds annotations to input gcode, e.g. path continuity
~~nc_contour_spiral~~
- Generate spiral toolpaths from gcode path

~~lathe_path~~
- generate lathe operations for svg path
- TODO determine machining strategy for lathe operations based on different tools and back faces
~~mill_path~~
- generate profile operation for svg path
- pick from SVG file with xpath pattern
- opt. scale / transform
- profile / pocket
