Hello. im new to this.. i bought a cnc machine about 4 years ago and never used it.. i did conected once then left it.. now i try to conected again and it does not show on my computer(windows 10) ive done updates on pc... but it just does not shows up on the computer when i hook up the usb cable.. like if it wasnt there... any help would be greatly appreciated. not sure if there is a place to get specific drivers for it... i watched a video on how to install software etc and no luck..
