Hello everyone I am a new user to MYCNCUK and I would like to wade in with a problem that I have so here goes........ " I have built my own control panel and every thing looks well, accept for I can't get my Mach3 software to hand shake with the Bluesky T AM9587 5 axis 100Kz motion controller, I have tried using 2 different USB motion drivers UB100 and RnR motion driver and both do not recognise the AM9587 brake out board by displaying ( not recognised plug in the cable and try again ) I assume that it means the USB cable which is connected so the USB drive is not for the brake out board ) dose any one know if there is a dedicated USB driver for AM9587 motion controller board.
