    Default Saturn 4x4 Wiring Help - Clearpath Servos / UB1 / UCCNC

    I had posted this in the Fineline Automation forum but I think it might get more viability here.

    I am getting my Saturn 4x4 built and have some questions regarding the wiring of the UB1 BOB with the Clearpath Servos and just general components. I thoroughly read both manuals and created a wiring schematic of what I think it needs to look like. In the end I am hoping to put this on a website to help others out as I am struggling to find a existing documentation on how to do this. I am also new to this so it is somewhat confusing. Any input would be greatly appreciated. Sorry for the crazy diagram but I did not know how else to represent it. I also attached a .pdf as it saves clearer. It would not let me attach my Visio.


    Diagrams removed till they can be sorted out and posted back for the community.

    I don't use the UB1 and its not very clear on your JPG diagram
    but I don't see how your series connection of the stepper driver enable inputs will work

    each of the drivers input opto-isolators (step, direction & enable) will have a current limiting resistor of about 300 ohms to limit the LED current (to about 10 mA) when you connect 5V across the input terminals

    the enable input of all the stepper driver I have looked at would be better called the disable input !!
    ( with no connection the driver is enabled , connecting 5V to the enable input will disable the driver )

    what stepper drivers are you using ?

    I am using Cleapath Servos so the "drives" are built into the motor.

    they don't make things easy demanding you to register to download the Clearpath servo manuals !!!

    If you google Clearpath Servo Sd manual it brings you right to the pdf with no registration.... makes no sense...

    now I have had a quick look the servo & driver step & direction inputs look OK
    I am still not sure of the enable wiring

    Hi Jeremy - That schematic is not correct. You might want to take it down so others don't get confused. I'll help you with the connections per our PM and in the end we'll have a working diagram.
