Ok, then you will need the Plug-in for the controller you are using. This is why the DRO's are moving but not the machine, mach3 only provides the driver for the parallel port so any 3rd party motion controllers need to provide a piece of software called a plug-in that tells mach3 how to talk to the external motion controller.

To be honest you'll probably find it easier to start again and use a better controller because the Chinese USB controllers are notorious for being rubbish and USB it selfs isn't very stable or reliable for CNC due to being easily affected by electrical noise. Many people upgrade to an Ethernet-based controller.

Personally, I would replace it with an AXBB-E controller which is a great controller at a good price, it also has its own software called UCCCNC which is much better than mach3 and also made by the same people who make the controller so it's much better integrated with the controller and it's fully supported, unlike mach3 which is no longer supported.

The AXBB-E will also work with Mach3 if needed, I just wouldn't because UCCNC is so much better.
