There are different ways of doing this. I would do it with a python remap.
Here is a basic example that creates an 'M456' command that generates a random number and stores it in a gcode parameter named #<_random_value>. You would need to add the other stuff with the file.
1. save this as 'toplevel.py' to a folder named 'python' in your configuration folder:
2. save this as 'remap.py' tot the folder named 'python' created above:
Code:
from interpreter import *
def m456(self):
import random
random_value = random.randint(0, 10000000000)
self.execute("#<_random_value> = %f " % random_value, 1)
yield INTERP_EXECUTE_FINISH
3. Add this line to the [RS274NGC] section of your ini file:
Code:
REMAP = M456 modalgroup=10 python=m456
4. make sure you have this in your ini file:
Code:
[PYTHON]
PATH_PREPEND= python
# import the following Python module
TOPLEVEL= python/toplevel.py
# the higher the more verbose tracing of the Python plugin
LOG_LEVEL = 8
5. start your config and run MDI command:
6. to check the result run MDI command:
Code:
(debug, #<_random_value>)
should return something like this:
