OK I am either not seeing the answer before me or the supplier is out to annoy me?

I brought a CNC 6040 machine off ebay and received the following items:

fully assembled CNC 6040 unit (sod to get out of the box)

VFD Black box 220v setup, EU plug (which I have got rid of and replaced with UK lead)

water pump

the X Y Z motors

USB to LPT connector cable marked up as CNC USB Connector

USB Connector software

Now after doing my research and asking around I understand that the USB to LPT lead is pretty much useless.

So how do I connect my PC to the VFD Box in turn to run the cnc machine???

I have since heard of U100 adapters but does everyone have to buy one just to connect their cnc machine or do I buy myself a LPT female to female connector lead?

I am so confused and have had the machine since end of November and yet still not used it.

any and all help is much appreciated.

Kind regards
