Hi!
I am quite new to EMC developing, and not really good with tcl and
python. Actually, I started this morning. However, I managed to add a
new menu-item to axis' File menu.
It is called "Filter", you choose an executable program, and after
pressing ok, the executeable is called with one parameter being the
currently opened gcode.
The program can do whatever with this code, e.g. remove all comments,
center it, modify it, and is expected to finally output some new gcode
to its output stream.
This stream is written to a temporary file , and reread as new gcode-file.
[The temporary file is named "filter.ngc", which is stupid, it should be
random. I don't know how to do this.]
This is functionally different from the filters is the open-file dialog,
as they have no access to the currently opened gcode.
The directory of the filters can currently be specified in the ini-file
of the machine, as entry EMC->FILTER_DIRECTORY = ....
Maybe there are better ways of accomplishing this, but I believe that
the basic functionallity is actually good.
Examples of filters that one could program and execute by this:
Center Gcode, MirrorX, MirrorY, ExchangeXwithY, Optimize paths,
FixIntendation, ....
Or a program that for a "schleppmesser" (sorry, don't know the English
name, a knife that is in the lathe, axially rotate-able, cutting a
fraction behind the actual position) includes the initial direction
moves and respects the delayed cutting.
Some of this codes I have already programed (flipping, N* removal), and
currently I use them from the shell.
Below is a difference between a git download I did yesterday and my
current code. The ini file changes are obviously just for testing.
So, what do you guys think, is this something that should be part of axis?
greetings,
