I am trying to accomplish the following, using 2.6.0-pre.
I have a basic 3-axis machine that has a sensor mounted, and I
am pretty darn close to having linuxcnc do the position and capture from
it, but could use a little help. I have remapped M200 - initialize the
sensor software, M201 - store data from the sensor, and M202 - close it
down.
I have the following remappings:
REMAP=M200 python=m200 modalgroup=10
REMAP=M201 python=m201 argspec=p modalgroup=10
REMAP=M202 python=m202 modalgroup=10
Gcode to move/process/move/process..... looks like
M200
G0 X 6.000 Y 2.000
M201
G0 X 8.800 Y 2.000
M201
...
And the python code, which is running, starts as:
def m201(self, **words):
global _images, _camera
if not self.task:
return INTERP_OK
for (word,value) in words.items():
MESSAGE("M201: %s: %s" % (word, value))
Question 1: If I do "M201 P3" I don't see the P3 come through. Is
there some other initialization that is required or am I making a
different mistake?
Question 2: The "if not self.task" successfully stops my code from
doing anything for axis preview. However, when I start my program
linuxcnc seems to
run through the code with self.task set before it starts any machine
motion, and then does the motion afterwards, rather than in-line as I
was expecting.
I've tried a number of alternatives, short dwells, etc. but no luck.
The question I suppose really is what is the proper gcode to
move/process/move/process. I suspect that I don't fully understand
code and modal groups.
Thanks in advance for any advice.
