I just set one of these up for a guy in Riverside last week. Its a Chinese import, it works as described in the ads pretty much. The control interface is a serial card installed in the a PC running proprietary software. The drives accept step & dir. inputs from an indexer (it would have to be re-wired to work with MachX). It is a heavy machine, and seemed to be a decent machine for the price. What do you want to know? It is not a scam.
