    If you only run one IBT2 from the psu, does it shut down?

    Yeah I started out with just one, then daisy chained 2 and then a third.
    Unless you mean keeping the 3 but only hooking the outputs of one to the psu, I haven’t tried that yet.

    Side question: this new motor, I had to attach my own wires to it. And I put on 12 gauge wires but I’m finding they get hot and soft when the motor is used for a while. Is that normal?

    Sounds like it is drawing more than the wires can safely handle.

    12 gauge wire is rated for around 20 amps peak, keep in mind sustained needs more overhead than peak.

    A 600W motor @ 24v should pull around 25 amps.

    I will try upping the wiring to a larger gauge and see if maybe this has something to do with my issues with the movement quitting

    ok! So I think I will mark this thread as Resolved. Let me summarize the things I learned and ways I got around the issues. Thank you to @noorbeast and @yobuddy for all the help debugging.

    - I needed to seperate my larger motor onto its own seperate Arduino board. When I had my smaller traction loss motor, and the larger heave motor on the same board I was getting what seemed like interference when running each motors seperatly though SMC3. One motor seems to prefer 25 frq and the larger motor was better at 35 frq
    - I also norticed some grounding issues when I bundled some of the wires on each board together in my project box
    - I needed to make my min and max values higher values so the motor wasn't too active, otherwise it was cutting out.
    - One big thing was I think I had too high a value set for the pwnMax in SMC3, I started at 0 again and inscreased while in the "sine" wavey motion until i had movement, then just went a little higher then that
    - I needed to increase the guage of the wire I was using for my 600 watt motor. I ended up using parallel wires, so three 12 guage wires for positive and 3 12 guage wires for neg. (make sure to use the same legnth and guage wires if doing it this way

    Also, I almost burned my house down by accidently swapping positive and negative wires on my new 1000 watt PSU, so dont do that :)

    Thanks again for all the help.
