A GCode sender for GRBL under windows, using DotNET 4.0 (should also work with Windows XP)  

Written in C# VisualStudio 2022.  

For use under Linux check this description by metzger100: [GRBL-Plotter-Linux](https://github.com/svenhb/GRBL-Plotter/blob/master/doc/GRBL-Plotter-Linux.md)

#### [GRBL-Plotter Vers. 1.7.3.1](https://github.com/svenhb/GRBL-Plotter/releases/latest)  2024-03-16     



### Requirements for compiling

* VisualStudio 2022 

* DotNET 4.0

 

## Feature list:

#### Import/Export:  

* Several options to translate Pen Up/Down

  - controlling a Z axis

  - controlling a RC-Servo

  - controlling a laser

  - user defined commands

  - Create GCode absolute or relative (for further use as subroutine)  

* Ruler and import units can be switched between mm or inch

* GCode import via file load, drag & drop or copy & paste

  - Loading GCode with optional replacement of M3 / M4 commands (helpful for 'Laser Mode' $32=1) 

* SVG graphics import via file load, drag & drop (also URL) or copy & paste - tested with [Inkscape](https://inkscape.org/de/) generated SVGs 

  - optional resize to fixed size

  - optional output of nodes only (generating drill holes for string art [Video 'String Art'](https://youtu.be/ymWi15rvTvM)  )

  - optional sorting of paths by used color

  - optional tool change

  - if text needs to be imported, convert text into path first

* DXF graphics import via file load, drag & drop (also URL) - tested with [LibreCAD](http://librecad.org/cms/home.html) generated DXFs 

  - few entities are missing

* [Drag tool compensation](https://github.com/svenhb/GRBL-Plotter/wiki/Drag-tool-compensation)

* HPGL graphics import via file load, drag & drop  

* Drill file import via file load, drag & drop 

* Gerber file import (rough implementation) via file load, drag & drop 

* CSV file import via file load, drag & drop

* Image import via file load or drag & drop

* GCode can be edited and saved

* Recent File List (Files and URLs)

* Export / import machine specific settings (Joystick, Buttons)

  

#### GCode creation:

* Create Text from hershey or windows system font

  - own created 'Dot Matrix' font [Video 'Dot Matrix'](https://youtu.be/ip_qCQwoufw) 

* Create simple shapes 

* Create Barcode and QR-Code 

* Create GCode via tool extensions 

    

#### Import options: 

* Process pen-width as Z-depth 

* Process circle radius as dot (optional with Z-depth) 

* Modify paths for drag knife

* Add angle information for tangential axis 

* Add hatch fill to closed paths 

* Repeat closed path for a small distance (for laser cutter)

* Group code by graphic-properties: layers, colors, pen-widths  

* Tile the graphic 

 

#### GCode manipulation:  

* Transformation of GCodes (scale, rotation, mirror, zero-Offset)  

any A,B,C,U,V,W commands will stay in place.

* Transformation via camera teaching

* Axis Substitution for Rotary Axis

* Radius compensation

* Convert to polar coordinates (X=radius, Y=angle)



  

#### Machine control:  

* Height map, auto leveling 

* Probing dialog 

* Individual commands via user defined Buttons  

* Joystick like control in user interface  

* support of no-name USB GamePad / Joystick   

* Optional usage of a WebCam with separate coordinate system: graphics overlay of the current GCode, set zero point, measure angle, zoom, teaching  

  - Shape recognition for easier teach-point (fiducial) assignment  

  - Transforming GCode with camera aid, to match drill file with PCB view [Wiki 'PCB drilling'](https://github.com/svenhb/GRBL-Plotter/wiki/PCB-drilling)   

  

#### Flow control:

* Supporting subroutines M98, M99 Sub-Program Call (P, L)

* Internal variable to support probing, e.g.:

  - G38.3 Z-50		(probe toward tool length sensor, stop on contact - because of deceleration stop-pos. is not trigger-pos.)

  - G43.1 Z@PRBZ	(Offset Tool with value stored on trigger of sensor switch)

  - examine SerialForm.cs for implementation  

* Progress notification via email or pushbullet 

  

#### GRBL:  

* Automatic reconnect on program start  

* Supporting GRBL 1.1 (and 0.9 also)

* Check for 30 kHz max. step-pin frequency 

* Supporting new GRBL 1.1 features

  - Jogging

  - Feed rate override

  - Spindle speed override

  - real time display GRBL states (in COM CNC window)

* Check limits of GRBL setup - max. STEP frequency and min. FEED rate in COM CNC window  

* Controlling a 2nd GRBL-Hardware

* Supports 4th axis (A, B, C, U, V or W). Status and control (special GRBL version needed)
