Execute direct commands to the AxiDraw plotter

Source: R/axi_cmd.R

These small utility functions are not concerned with plotting, but rather lets you query information about the plotter or execute small commands useful for setup.

axi_version(options = axi_options())

axi_sysinfo(options = axi_options())

axi_toggle_pen(options = axi_options())

axi_align(options = axi_options())

axi_pen_test(tip_size, line_overlap, options = axi_options())

axi_pen_align(x_offset = 0, y_offset = 0)

Arguments

options

An axi_options object. See the documentation for axi_options() for all the settings. Many are not relevant for these function.
tip_size

The size of the tip (i.e. the width of the line it draws) of the initial pen
line_overlap

The overlap between adjacent pen strokes when filling out shapes and drawing thick lines, in mm. Setting this to a negative amount will cause gaps between the lines.
x_offset, y_offset

The offsets in mm to test

Details

The different functions have various, unrelated, uses:

  • axi_version() returns the version of the AxiDraw software

  • axi_sysinfo() returns the EBB firmware version and system information

  • axi_toggle_pen() toggles the position of the pen (raises it if lowered and vice versa)

  • axi_align() raises the pen and turns off the stepper motors so the carriage can be moved freely.

  • axi_pen_test() will test the look of filled areas with respect to a specific pen setting

  • axi_pen_align() allows you to test different offset values between two pens to determine the correct setting.
