General Mach Discussion / Coordinates reading from RS232

« on: January 16, 2012, 11:20:13 AM »

Hello!

I have a cnc under mach3, equipped with optical lines and external DRO. The external DRO has RS232 port and it can send continuously the value of the 3 axis. I'd like to receive this values in mach3, when i push a button, so i can update mach3 DRO with value of external DRO.

For test I try to send data from mach3 to another PC with hyperterminal, and it work correctly using 'call sendsendserial'. I set RS232 proprieties in Config/Logic windows in mach3.

For receiving data i try to use this VB script:

data = "none"
q = 0
while data = "none"
  q=q+1
  if q=10 then
    message "receive error"
    exit sub
  end if
  settimer(1)
  while gettimer(1)<0.5
  wend
  data=getfifoentry()
  message data
wend

It must wait about 5 second testing the serial port, then if it doesn't receive data, show error message. I try to send some data to mach3 after script start, but it can't receive anything and after 5 second it show the error message. I think there are some bug in my script but i can't find them... could you help me?
Thank you!

VB and the development of wizards / VB and spindle

« on: December 12, 2007, 07:27:06 AM »

Hi,
I'm trying to realize some macros to manage better my cnc, but I find some difficult.
In particular in a VB macro I need to detect if the spindle is on or off, and execute the macro only if the spindle in off, or ignore it if the spindle is on, but I don't know which parameter I have to test. How can I do it?

Thank you!
