Can anyone please help a novice . I have purchased a plasma from China with a cnc plug in the rear.i have connected a wire to the plug  and back to my relay which has 3 wires 1 live 5v 1 negative and one switching  wire the switching wire is connected to pin 4 on my usb motion controller card . I have set up in ports and pins-spindle setup . Rely control clockwise(m3) output#1.  Ccw (m4) output#1
Output signals output1 enabled port 3 pin4 yet it will not fire up when I push the torch on/off button or when I run the test Gcode that is in macro3 . I have a 5v power supply connected to the motion card and if I put a wire from the 5v power point on the board to the switch wire on the board the torch fires ,but I cannot get it to fire any other way please can some one help
