Many thanks for that link, Michael. And I thought that: http://www.linuxcnc.org/docview/html/gcode_overview.html#sub:Named-Parameters was the definitive reference on the subject. There are more hidden gems in the LinuxCNC documentation warren than any single human knows about, I suspect. I'll update the code generation to exploit those predefined named parameters which you've revealed. Although it'll only save a gcode assignment at each G90/G91, it'll be more canonical in its machine state testing. > If that doesnt suffice, go to the embedded Python level which has > practically all of the interpreter state exposed, and then some > (task). > > See tests/remap/introspect/oword.py for state access. Seeing there, things like: self.params["a_new_local"] = 321.0 I'm tempted to guess (based on zero prior exposure to python), that that's probably a hash.¹ Having that available in bison would have made the symbol table much easier to implement. ;-) > Exporting state from Python is left as an exercise for the reader;) Since the translator could be run as a filter or off-line, tests need to be executed in gcode, so that they're real-time. I don't know of a method to run in-line python in gcode, and have yet to see a need for it, anyway. The predefined named parameters you've shared do it for me, AFAICT. My belief that LinuxCNC was limited was largely based on a post from: Date: Mon, 6 Feb 2012 13:27:12 +0200 » if (SpindleMode=CSS) uimessage "some relevant message" That can't be converted to generic G-code because generic G-code is bad at strings and has no mode introspection. « and the absence of any contrary thoughts on the list in the last several years. But it turns out that even #<_spindle_css_mode> is available. Thanks again for finding the treasure.
