Anyone have any ideas? I'm dead in the water right now.
Possible solution;

I have an 80w laser with Ruida controller. I have a blinking led pin 14. I recently had a no fire on my laser, however, changing out the power supply unit solved that issue.

Does anyone out there have suggestions on how they get the ruida controller to read either USB or through the PC cables. I have a hp elitebook 8540W running windows 7
