Just got my K40 machine today,

Just got my K40 machine today, but without CD and can’t get the USB to work, anyone knows?

Here are the contents of the CD: https://www.dropbox.com/s/86ib5q5i9jvk4xs/Laser%20Cutter%20-%20Easy.zip?dl=0

And the USB is just a key which allows the machine to work. Think of it like a key to your front door… except in digital form.

Hope this helps!
