skeinforge_tools.export_plugins.binary_16_byte ($Date: 2008/21/04 $) | index /home/enrique/Desktop/backup/babbleold/script/reprap/pyRepRap/skeinforge_tools/export_plugins/binary_16_byte.py |
Binary 16 byte is an export plugin to convert gcode into 16 byte binary segments.
An export plugin is a script in the export_plugins folder which has the functions getOuput, isArchivable and writeOutput. It is
meant to be run from the export tool. To ensure that the plugin works on platforms which do not handle file capitalization
properly, give the plugin a lower case name.
The getOutput function of this script takes a gcode text and returns that text converted into 16 byte segments. The writeOutput
function of this script takes a gcode text and writes that in a binary format converted into 16 byte segments.
Many of the functions in this script are copied from gcodec in skeinforge_utilities. They are copied rather than imported so
developers making new plugins do not have to learn about gcodec, the code here is all they need to learn.
This plugin is just a starter to make a real binary converter.

Byte 14 is worth a few extra notes, this byte is used to define which of the axes are active, its used to get round the problem of say a
line of code with no mention of z. This would be put into the file as z = 0 as the space for this data is reserved, if we did nothing, this
would instruct the machine to go to z = 0. If we use the active flag to define the z axis as inactive the z = 0 is ignored and the value
set to the last saved value of z, i.e it does not move. If the z data is actually set to z = 0 then the axis would be set to active and
the move takes place.
