Hi Philipp, a bit of guts first:
Configs with a UI which sports preview actually have two interpreters there's one in the milltask process - this is the 'real one' which drives the machine, and which you've been talking to with your sample program then there's a 'preview interpreter' in the UI process, which doesnt generate canon commands to drive the machine, but rather lines to be displayed in the UI. in principle those two are unrelated ; of course they should work on the same ngc program. UI's deal with that by telling the preview interpreter to generate preview, and tell milltask to actually execute the program driving the machine. what happened with your program: you talked to the milltask interpreter, which bypassed the UI - it cant possibly know of the new file you might want to study axis-remote and the code in UI's to achieve the desired effect: http://linuxcnc.org/docs/html/man/man1/axis-remote.1.html -Michael Am 30.12.2013 um 17:28 schrieb Philipp Burch <p...@hb9etc.ch>: > Hi all! > > Maybe you remember my question of a few weeks ago about a more flexible > way to transform the coordinates in a G-code file: > http://sourceforge.net/mailarchive/forum.php?thread_name=528A6D98.7080208%40hb9etc.ch&forum_name=emc-users > > My decision was then, to do most of the transforms in Python and > generate the G-code as needed.
