Help with Mach3 inputs and VB script ?

[JAZZCNC]

Look at using brains has they can watch an input and respond to it much quicker than a Macro.

But what your doing is wrong any way I think.? Why have you got Mach involved in the E-stop at all.? All you should be doing is informing Mach an e-stop has occurred. The only involvement Mach should have is to halt the running G-code and then Refuse to RESET SOFTWARE if it doesn't receive a signal saying the E-stop circuit is safe.
It shouldn't be involved in the E-stop Circuit at all and if the Circuit is safe MACH should be safe to RESET SOFTWARE.

If you include the Charge Pump Signal in the E-stop circuit then If E-stop circuit is safe MACH will See the Charge pump signal and allow SOFTWARE RESET then you can continue with CYCLE start and running the Program..

Now I'm highlighting SOFTWARE RESET because this is different to the Momentary Reset you'll want to bring the Control back to life if all is safe.
