GRBL-Plotter Vers. 1.5.0.5 2020-08-15

Requirements for compiling

  • VisualStudio 2015
  • 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 generated SVGs
    • optional resize to fixed size
    • optional output of nodes only (generating drill holes for string art Video 'String Art' )
    • 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 generated DXFs
    • few entities are missing
  • 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
  • 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)

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

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'

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 [email protected] (Offset Tool with value stored on trigger of sensor switch)
    • examine SerialForm.cs for implementation

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)
