To state the obvious, this is not exactly the often-asked question about whether you can use linuxcnc on a computer with only a USB port ( know you can't). I already have the parallel port, I need a way of translating the parallel port's output into a USB format, if this is possible.

Thanks
No you cannot use USB to control linuxcnc. But depending on the mill you could just use a simple Chinese BOB connected the the P/port.

You could even use the same PC as the router but not at the same time. ie. you can have two different configs one for the router and the other for the mill

It would help if you could give more info and pics of the mill. What version of Lcnc are you using?
