We designed a custom cable that attachs to an unmodified Syil X4+ MPG via a DB15 male connector and to the PC via a DB25+USB.
Whats the point of it? You can use the MPG and not lose the references and softlimits.
Of course, the MPG can be used with any machine, for example I used it with a SX3
Here is a video I just made:

Hope you all like it
