    I had the wrong config loaded… after rereading everything for the umpteenth time I realized that I need to load the modified config posted below

    I only have a multimeter, I checked accross the inner and outer pairs of the STEP1 and STEP2 pins.
    On STEP1 (which is working) I get fluctuating voltages as expected, on STEP2 I get a constant 1.5V

    I’m basically at the same point, home only moves the lower arm. If I swap around the stepper motor cables on the board at STEP1 and STEP2 then the top arm rotates, but not the lower. I swapped around the stepper drivers and the top or lower arm rotates depending on which one is connected to STEP1.
    So stepper drivers are good, stepper motor cables are good.
    I resoldered all the joints on the board in case I missed something, or had a dry joint.

    Just as a side note, the stepper driver heat sinks burnt my finger when I accidentally touched them, they were super hot. Vref was set at 1.2V and I dropped it to 0.8V, they are running much cooler now.

    Axle Stabilizer x2.stl
    bottom gear lock optical limit v2.stl
    Elbow Clip Optical Endstop v5.stl
    ElbowGear.stl
    Furniture DC and USB panel v5.stl
    LED Holder.stl
    Lower Arm 184.5.stl
    lower optical limit switch holder v3.stl
    LowerCenterGear.stl
