I'm trying to figure out what gcode.parse and gcode.calc_extents does and how to use it. I've been grepping and searching for examples but I've not found out the syntax and what is returned.
Code:
help(gcode)
calc_extents(...)
Calculate information about extents of gcode
parse(...)
Parse a G-Code file
Not much help there...
With axis running and a terminal open and running python3
Code:
>>> gcode.parse()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: parse() takes at least 2 arguments (0 given)
grepping I find this example in src/emc/usr_intf/axis/scripts/axis.py:1589:
Code:
result, seq = gcode.parse("", canon, "M199 P["+e+"]", "M2")
Code:
>>> gcode.calc_extents()
([9e+99, 9e+99, 9e+99], [-9e+99, -9e+99, -9e+99], [9e+99, 9e+99, 9e+99], [-9e+99, -9e+99, -9e+99])
So what I'm trying to do is display g code on an PyQt QtOpenGLWidget... I think I should be using the glcanon.py from lib/python/rs274... but not sure. I've been thrashing around for a couple of weeks and have not made any progress. If someone has a clue please let me know.
