#!/bin/sh
# file to turn on paraport pin 14 to open the collet closer
halcmd setp parport.0.pin-14-out True
exit 0

there's no partport subfolder Pin

the folder Pins only have :
+axis
+axisui
+comp
+ddt
+hal_manualtoolexchange
+halui
+hypot
+iocontrol
+motion
+or2
+pyvcp --> program
owner = 12
type = bit
dir = out
value = False
Name = pyvcp.program ==> btn1

when i click the button there's nothing happen....
anyway sorry to disturb your time John....

can i have a parallel port driver to configured ?

i'm trying to make a button at EMC2-Axis and i want that button can execute my program.py...i'm really stuck here for 1 week....

i dont know that i must turn on a parallel port....

why pin 14?
because i read from the link that u gave me before....

sorry, i'm really noob here...but i really want to study this software...

>.<
when i rename "program.py" into M101 i must change the

<halpin>"program.py"</halpin> into <halpin>"M101"</halpin> ??

net halui.mdi-command-00 <= pyvcp.program
net halui.mdi-command-00 <= pyvcp.M101 ??

From the link "The external program "M1nn" must be in the directory named in [DISPLAY]PROGRAM_PREFIX in the ini file and is executed with the P and Q values as its two arguments. Execution of the RS274NGC file pauses until the invoked program exits. Any valid executable file can be used."

i dont understand to configured P and Q values....
two arguments mean, i should have M101 and M102 ??

want to cry...... >.< why it's so hard...... >.<
