I spent all day for checking the connections and found some problems(bend pin on axis3, 2 wires than wasn't connect in buttons), but this wasn't help me.
I didn't notice one important thing earlier.
EN led on 256A module blink 2 times during startup then go off. When i go to manual mode and press button on TP halfway, rest of the leds (GS, MS etc.) light up, so runchain 1 and 2 are ok i think. In auto mode all led are on, without EN led.
Maybe that's problem with Enable chain open fault 10004?
And one more thing, F led on digital I/O board is on, but there's maybe problem with settings parameters (All equipment for welding is connected, but not set in fresh system), but i'm not sure about it.
So i don't know which board buy, the 256A or 325, or maybe both of them?
