RE: [CAD_CAM_EDM_DRO] Re: USB-DRO now available

Its about time somebody makes something like this. There are several out there that I've looked at, but they always fall short. They either run DOS only or the interface is exspensive and the user has to assemble it. Theres always some quirk.

Thanks Fred!!
