    Thanks for your reply.

    I have a Cbeam machine from Openbuilds. There have been no customization to the machine so it is not a custom build.

    I have read the connecting and configuring sections but still am at a loss for what to do really. Even when I try to move the Y-axis by itself (and not have a dual Y axis setup), the lone Y axis does not work (when attached to motor 2). I have stripped the motors from my cbeams machine and am just working with the motors by themselves. Motors 1 and 3 work flawlessly, but I’m still having trouble getting any movement from motors 2 and 4 at all.

    Thanks so much for your response,

    Please see below for my dropbox link with the parameter dump from the console:

    Two(of many) possibilities for your bigger issue
    PWB/mechanical: If you have a multimeter, follow the trace from each output screw block back to it’s respective output pin on the 8825 drier device.
    Then measure the resistance from the device lead to the connector screw head. It could be an issue with the connector body.
    While you are at it, double check the connections closest to the steppers, most installations have 4 wire 18ga or so cables between tinyG and the steppers, with connectors/splices near the steppers to the 24ga (or so) leads into the steppers. It is easy to bork the connections.

    My apologies, I’m new to CNC/controller boards. I’m not quite sure where each of the items you mentioned are (ex: output screw block) located on the TinyG. To aid in our discussion, I have taken a picture of the TinyG (and included it in the Dropbox link) and have written the individual items that I am supposed to locate in colored font. May I ask that you use MS paint or other software to point an arrow to indicate the location of the items on the TinyG? Alternatively, I am more than happy to send the board back to Synthetos and pay a fee so they may diagnose it on my behalf.

    Thanks
