Lightburn console repeatedly enters g

I have a jtech 7w on a shapeoko 3. when I open the console in lightburn “g” is repeatedly entered even with the shapeoko and Jtech disconnected. I don’t believe its the keyboard as the same thing does not happen in notepad

LightBurn sends ‘G0’ to the laser to see if it’s there. When it gets an ‘ok’ reply, it knows there is a laser connected.
