    Sad and unsatisfied update!

    Had 20mins over today so I ran to the shed.
    Realized I read the connections wrong for the relays. Reconnected and got the master relay to latch with start button. And disconnect with e stop!

    Problem 1. Something is wrong, when I e stop I kill power to 5v psu . This makes my uc300 disconnect from pc and a restart is required for uccnc to connect with uc300 again.
    Will look over the wires and reconnect with 5v outside of that loop.

    Problem 2. Red fault light is on at all 4 drives.
    Guessing it has to do with the enable signal.. since its not over or under voltage (get 50.6v ac at drives they take up to 80v ac or 110v dc) and no holdingtorque so no over/under current. Have tried enable through bob aswell as running ena- straight to gnd.
    This could have something to do with my bob aswell? The bob has a green led shining by the 12-24v sign. But a red led right by the 5v pwm text.. is this normal or is it a error?

    And another question!
    How do I know the port nr to use in uccnc?
    Easiest to connect switch and watch in ports and pins whats flashing? :)

    Go back to basics. Disconnect the enable wires and see if they come on.

    Unless your 100% sure and confident that the schematic you have works it's always a good idea to wire in stages. Start with just powering up and seeing if latching system works and you have power to right places at the correct voltages.
    Then start introducing things like enable or fault monitoring etc.

    Ideally you should have written down all the I/O pin# your using and what's connected to those I/O #'s. Then when you have any trouble you can start tracing wires from that Pin# back to it's device. Makes trouble shooting so much easier.

    You are of course correct :D
    Will go back to basic when time is available!

    Im an idiot!

    But a happy idiot :D

    Got the drivers powering up WIIIHOOO!

    Sad to say I did something wrong with the steppers. But after some old fashioned anger I found what I did :D
    Have adjusted two motors and can now claim some kind of movement on x axis!
    Two motors left to adjust and then I might be getting real movement! Yeah!!

    The first movements on the first router builder are all the sweeter because it's when you get to see if you actually got it right ;)

    If you didn't buy it from China the company you bought it from did ;)

    If anyone have the same problem as I had with uc300usb and e stop then I think I found a fix.

    I hadn't made an error connecting it but it had a jumper that controlled if it was powered via usb or external 5v.
    I had it on usb supply apparently and this somehow got triggered by e stop (interference or current surge/dip?) Causing the controller to loose connection to uccnc.

    Now I have tried it with power from stable 5v supply and nothing happens with the connection when e stopping, well except the pc senses e stop as it should :D
