Light burn can't find longer ray 5 20 watt

Light burn can’t find my longer ray 5 20 watt laser engraver using Hp windows 11 laptop. Any help will be greatly appreciated. Also the screen on my laser has never turned on, This is a new laser I got in January of 26’. Long story short, i bought the extension kit and extension wires didn’t match the original wires am hoping I didn’t fry something. Originally put it together using extension kit .

This suggests a key switch is in the wrong position or the E-Stop button is depressed (twist to unlock).

The E switch works fine. Only the fan on laser head turns on .

  1. Does Windows make a tone when you plug or unplug the USB cable with the laser power on?
  2. What is displayed in the Console window?

It does not make any sound.

Did you install the CH340 driver? USB needs it to operate as a serial cable.
