tkCNC Editor is a text editor, specially designed for CNC code (G-code) editing for CNC machines. It is used by CNC programmers and operators for fast editing and control of CNC code.

tkCNC Editor version 2.0 has implemented these functions:

• MDI (Multiple document interface) – allows editing of multiple CNC documents
• G-code syntax highlighting
• Multiple Undo/Redo
• Print Preview – CNC documents preview before printing
• All standard text editor functions such as Cut, Copy, Paste...
• Fast CNC blocks renumbering
• Find/Replace function with special features for CNC code searching
• Fast points import from AutoCAD
• Generator of circular and rectangular point patterns (coordinates)
• Smart CNC code templates
• Various operations with CNC code registers such as: mirroring, renumbering, translation, rotation, basic mathematical operations (+,-,*,/), sorting etc.
• Conversion of 2D coordinates from polar to Cartesian system and vice versa
• CNC code registers swapping
• CNC code registers sorting (order in block)
• 3D tool path simulation with possibility of export in AutoCAD or DXF file (Simulation supports CNC code analysis block by block, coordinates viewing for every tool-path point, tools diameter representation)
• Degrees conversion from Degrees/Minutes/Seconds format to decimal format and vice versa
• Automated CNC documents joining
• "QuickCalc" function implemented in text editor window for quick calculation of simple mathematical expressions directly in code
