NCPlot is an editor and backplotter for 4 axis mill and 2 axis lathe G-Code programs.  This software combines editing, formatting and translation tools that are useful for CNC programmers with a backplotter for instant G-Code verification.

NCPlot features:

Full featured text editor Unlimited undo/redo Cut, Copy and Paste Find and replace Font and color settings may be applied to any part of the program Address coloring improves program readability Program formatting tools   Remove block numbers, blank lines, comments or spaces Program renumbering with automatic updating of: Macro GOTO references M98 H_ references (for controls that support this) M97 P_ references (for HAAS style subprograms) Lathe G70 - G73 "Q" and "P" addresses Insert spaces between letter addresses and macro keywords Fix invalid end of line characters Convert programs to all caps Add or remove comment or block skip characters Program translation tools Mirror Rotate Shift Scale Address Adjustment:  Apply math operations to any program addresses Address Replace:  Good for changing axis names, A to B, etc. Address Remove:  Unnecessary addresses and their values can be removed Address Swap:  Exchange any two program addresses Convert absolute I / J / K arc center coordinates to or from incremental I / J / K Convert  R specified arcs to or from I / J / K specified arcs   Customize NCPlot:  Preferences, Subprograms, Machine Configuration       Flexible viewport control A wide assortment of plot controls lets you quickly find any mistakes in your program. 7 view modes for Mill and 2 for Lathe Dynamic zoom, rotate and pan Animate, step forward or step backward Draw to the cursor, from the cursor or just the selected portion of the program. Clicking an entity on the viewport will display the entity properties and highlight the associated block in the program.   View Controls   Many easy to use view controls to quickly zoom, pan or rotate the display.   Calc Tools Select entities on the viewport to quickly calculate offsets, blend arcs and find intersection points.   DXF importing / exporting   Import DXF drawings to quickly create G-Code for both Mill and Lathe. Any backplot can be saved as a DXF drawing file for loading back into a CAD or CAM system.

Advanced G-Code Backplotter includes support for Custom Macro B Backplotting for Mill and Lathe programs. Backplot macro programs offline! Can be customized for different control requirements. Built in macro expression calculator lets you test macro expressions and set and view variables Step by step execution of macro programs allows you to watch program variables as the program is executed Breakpoint expression allows the program to run until the expression becomes True Subprogram display allows you to follow program execution even into subprograms that are not in the loaded file   Backplotter supports: G65 macro subprogram calls M98 subprogram call in multiple command formats Plane selection G17, G18 and G19 Helical arcs Automatic corner rounding, corner chamfering in G01 motions Work offsets G54 - G59 Extended Work offsets G54.1 P1 - P300 G52 Local work shift G92 Coordinate system setting G16 Polar coordinates G51 Coordinate scaling G51.1 Mirror image G68 Coordinate system rotation G66 Modal macro call Local, common and some system variables Macro keywords IF, THEN, GOTO,  WHILE, DO and END Other Tools   Macro Translator Execute variable macros offline!  All variable commands are evaluated and the resulting values are used in their place.  This creates a standard G-Code program that can be run on any machine.  NCPlot comes standard with macros for bolt circles, grid pattern and others. Support for VBScripting Many of NCPlot's internal functions are available for scripting.  This is a powerful tool that makes it possible to automate many common tasks such as converting files from one machine to run on another. Text to G-Code converter Instantly create G-Code from font outlines.  Great for etching, creates lettering of any size, on an angle, or even on an arc. Macro Expression Calculator This built-in calculator accepts expressions written in Custom Macro B format.  This tool can also be used to view or set variable values.
