  • Cube
  • Cylinder
  • Sphere
  • Translate
  • Union
  • Difference
  • For cycles
  • Trigonometric functions

Usage

Openscad2CNC [input_file] [output_file] [metric] [bit_diameter] [XY_step] [pass_depth] [safe_height][seek_feed] [XY_cut_feed] [plunge_rate] [pull_speed]

[input_file] OpenSCAD source file.

[output_file] File where the generated G-code will be stored.

[metric] Boolean value. true for file in mm, false for file in inches.

[bit_diameter] Diameter of routing bit.

[XY_step] Units between parallel cutting passes.

[pass_depth] Units the bit travels on Z axis on each pass.

[safe_height] Safe height between working surface and bit end.

[seek_feed] Speed in inches per minute for G00 commands.

[XY_cut_feed] Speed in inches per minute for G01/02 commands.

[plunge_rate] Speed in inches per minute for G01 commands on the Z axis.

[pull_speed] Speed in inches per minute for G00 commands for the Z axis.
