Using an macro with an argument
Hello!
I have some trouble to fix some code in an macro i want to use. I tried in SimCNC 3.5 .
I want to use one macro (called M300) with 12 arguments (A1, A2, A3 ... and so on).
When i create following macro:
# M300.py
def M300_A1():
print("M300 A1.")
# Codedummy
def M300_A2():
print("M300 A2.")
# Codedummy
def M300_A3():
print("M300 A3.")
# Codedummy
def process_M300(arg):
if arg == "A1":
M300_A1()
elif arg == "A2":
M300_A2()
elif arg == "A3":
M300_A3()
else:
print("Invalid Argument. Choose A1, A2 or A3.")
if __name__ == "__main__":
import sys
if len(sys.argv) != 2:
print("Using: python M300.py <Argument>")
sys.exit(1)
arg = sys.argv[1]
process_M300(arg)
I tested to run it in the MDI. When i enter M300 A1 etc. i get following error message:
Warning
Motion (group 1) is not set
M300 A1
I cant figure out how to solve this.
Maybe you got an idea?
thanks!

Hello,
Because of how Python scripts are internally implemented in simCNC, standard argument passing (through sys.argv) will not work.
You have to use machine params for that manner.
It works like this:
- set machine param or multiple params beforecalling a macro
- read these params in a macro using getMachineParam function
example m300.py:
#m300.py
value_a1 = d.getMachineParam( 1000 )
value_a2 = d.getMachineParam( 1001 )
print(value_a1)
print(value_a2)
execution example from gcode:
#1000=1 #1001=2 m300
