    Default Hobby CNC 4AUPC Rev 1 Documentation

    I'm trying to help a friend with a machine he inherited. It has Hobby CNC 4AUPC Rev 1 board. I've searched the net over and can't find any documentation on it. Would anyone here happen to have a copy?

    Any help would be much appreciated.

    Hi Jerry

    if no one has the documents you need then you may be able to piece together the information
    from the stepper driver IC data sheets and later Hobbycnc boards like the hobby cnc EZ board

    SLA7062M

    HobbyCNC ez-M3 Schematic

    Hobby CNC  4AUPC Rev 1 Documentation-hobbycnc-ez-m3-schematic-1-pdf

    note - the sla7078m ic's used in the HobbyCNC ez-M3 board have built in 0.155 ohm current sense resistors



    so far I've only found a photo of a 4aupc board

    the older SLA7062M ic requires two resistors on the pcb see R51 to R58 in the photo

    Have you asked HobbyCNC for the documents?

    I KNOW HobbyCNC has the latest version of them for the asking. No need to post them here. Jerry hasn't been back on since his first post. I think he has his solution.
