Application examples

Multiple file loading
Adjusting pen-width via Z axis
Adjusting pen-width via S value
Fiducial correction via probing

Multiple file loading:

  • SVG-Icons downloaded from and unzipped.
  • Select some files and drag & drop them on the GRBL-Plotter icon or drag & drop on the 2D-view area of the already open program.
  • Files will be loaded in unknown order, imported with given options and arranged as defined.
  • Each file content will be surrounded by a "collection" tag, to be selectable

Machine limits:

Multiple file loading - 3 in a row, 2 mm gap:

Fiducial correction via probing:

  • Insert fiducial markers into your graphic, by adding them into a layer called 'fiducials' or name the graphic object 'fiducial'. Example: graphic
    Key word is set in [Setup - Program behavior - Camera - Fiducials].
  • After importing the graphic, the fiducial coordinates are listed in the probe-window 'Fiducial correction'.
  • Place metal fiducials markers (coins, washers) onto your workpiece.
  • To make starting easier, move the probe over the first reference point to trigger already. If indicator doesn't work, perhaps an old grbl version (before 1.1) is in use.
  • Press 'Start'.

Note: Offset between probe and tool must be teached first:

  • Perform 'Center finder' on metal fiducial - probe work coordinate will be set to 0;0 at the center of the fiducial.
  • Move the tool (pen) exactly to the center of the fiducial.
  • Take over the moved distance as offset (press button 'Get pos.').
