Hi All,
I have a JCUT6090 router from China. It was made as a 3axis+rotary. It has a PLCX6045M USB motion card in it. All 3 axis are wired into it, and there are screw in terminals for the A axis too. I got a new driver for the A axis, but  nothing happens, when I wired it in, the rotary doesn't work. If I swap it for the X, than it is OK. Hood, and an engineer friend of mine think that their plug in doesn't support 4 axis. Talked to the manufacturers, and they want to send me another motion control card that'll run 4 axis. If there is someone out there that had similar problems, I like to hear from you please.
