GCode Builder

Programming interface to build gcode, and make it possible to use scripting to dynamically generate tool paths.

Limitations

CNC only.

Different levels of abstraction when building G-code.
- G-code level should be available.
- Geometry helpers should be available (blocks).
  - Circles.
  - Rectangles.
  - Zig zag.
  - Planing.
- Block editing tasks should be available.
  - Holding tabs.
  - Stepdown.
Optimizers in each level.
- Optimize program by calculating the least amount of traveling.
Decorator pattern for decorating a Program, or decorating a Block?
- Decorating a block with holding tabs?
- Decorating a Program with a machining step?
  - Cutout.
  - Engraving.
  - Drilling.
  - Planing.
Should not be able to add a block to a block, just blocks to a program.
Command -> Block -> Program -> Job.
- Purpose of each?
  - Command - Obvious - Primitive - Lib
  - Block - Group of Commands - Primitive - Lib
  - Program - Collection of blocks - Primitive, extendable - Lib
  - #### Not part of lib below ####
  - Job - Extended Program w. parameters/conditional block construction.
No need for tool change if the correct tool is already loaded.
- Virtual machine?
Add operator hints and help in jobs.
- Description of the job.
  - Where is the origin? Orientation etc.
Support for adding blocks at specific positions:
- After another block, using IDs of some sort.
- First, last.
