Hi, I am new on the forum,

I do install usb controller on cnc with no problem , but I bought a USB 6 axis controller that the output will close but when it open the relay stay on,

I have connect it like the diagram they have supply...

so the problem if I start output 2 for spindle start it will never close...the relay will stay on, even if I have install diode or resistor...

Any help will be nice, I have 2 usb board ( one 3 axis one 6 axis ) both have the same problem


thanks Erik
