If you'd like to do some tests for the DAC-to-amp connection, you might try the following. Forgive me if you've already done this. Connect up all three amps as they have been. Then disconnect the input of one amp from the wire going to the DAC, and using a short piece of wire connect the amp input to its analog ground right at the amp. Leave its output connected to the motor, and see if you get any movement on that axis when the other axes are moved. If not, remove the jumper and reconnect the cabling from the DAC to the amp. Then disconnect the wire to the amp at the DAC end and short the disconnected wire to the DAC ground at the DAC. Leave any other ground connections in place since that may be part of the problem. Then see if you get any movement when the other axes are moved.
