I have a second LPT port (LPT2) which is used for an ATC and a couple of other relays. One of these is
currently hooked up to a Laser Cross Hair system. I have configured this to...
Output #3 Port 2 - Pin 16
It works fine when using M8 (on) and M9 (off). However, I'm confused with the M9, as I am also using this to turn off the ATC air solenoid (turned 'on' with M7). I have a line of code similar to below....
G0 Z-47.5 (lowers Z axis to place tool in holder)
M7 (turns on air solenoid to release the tool)
G4 P2 (wait for tool to release)
G0 Z-40 (move up to clear the tool holder)
M9 (turns off the air solenoid)
I would like to add an M8 before the M7 to turn on the Laser cross hair and then leave on, but the M9 turns it off again!
I suspect VB Code is the answer but trying to stick to G Code?

Simply create your OWN Mcodes to be used in Gcode. Store it in the Mach3/ Macro directory. Then call it when needed via Gcode program.
example:
M100 turn ON output
M101 Turn OFF output
