The lasercutter electronics are powered through the USB connection and not through the main lasercutter power electronics.

This is confusing to the user. One has to always remember to plug in the USB cable when using the lasercutter.

There is potential for dangerous power loops between the lasercutter and the computer which might result in burned chips.

Change title tag to K40B for clarity, as we have 2(3) K40 class machines.
The currently configured unit (that this issue refers to) is labelled K40B.
