I cant connect the PC to the laser unit. Software wont recognize the laser. Ezcad2 and LightBurn both dont connect.

There is something wrong with the Ezcad driver.  
Maybe you can re-install the driver.

I had this issue - I disabled Norton when installing the galvo driver from Lightburn and it worked. Before that if I used the EzCad driver neither programme would see the laser. after using the Lightburn one it would see it but not switch the laser on. I looked at the driver and it said it had been stopped because of an issue with the driver. So I disabled Norton and re-did it and it worked.
