Let me first start out by stating the reason for this circuit. I have built a CNC Vertical Mill. I am now in the process of trying to create a wireless probing system to aid in the setup of machining work offsets. I have a working receiver, that when the machine input pin doesn't see 5v the receiver the machine doesn't think a probing strike has been triggered. So if i take a regular tv remote and constantly press any button the receiver is happy, and when i let go of the button the receiver senses it as a probe hit. I am trying to recreate this with an IR Transmitter circuit. I have the circuit mostly working, as in the transmitter will send a trigger to the receiver, but it is only a short hit. I need for the transmitter to act like the button is constantly pressed on a remote until the trigger is broken, then stay that way until the button is pressed again. Currently the transmitter will just get the receiver to blink and not stay in the on or off state as long as the button is pressed or not pressed. I am attaching a schematic of my current circuit.
