Hi Tweakie

No communication at all.
Maybe optocouplers are burnt, but why LPT pins doesn't change state in Mach3's Diagnostic?

FAQs / PC / Relay board communication problem

Hi there great community!

It was beautiful day when I completed assembly of my cnc project until tried to test it...
Following carefully configuration instruction I was trying to play with relays on breakboard.
And nothing has happen (0x378 LPT adress and correct pins setup) 
I noticed "Port 1 Pins current State" indicator  does not change as I turn on/off spindle and flood (ESTOP was fooled).
I was trying to checki if address is correct in bios but found only LPT IRQ set to 11.
What should I do/check?

I work on Dell SX260, Windows XP Professional Edition , Mach3 + uServo Kit http://cncdrive.com/
