A lot of drives do NOT like SMPSs, for a very good reason. The remaining high frequency noise on the supply can send the driver mad. That is the main reason you are recommended to use a very simple transformer/diode/capacitor PS for the motors.

Re: 1st Build, will this be a decent Design?
You can put in a diode and a buffer capacitor. That is how the SMPSs are connected in my machines. The diode protects the PSU from the spikes and the capacitor buffers the voltage. And you can parallel the SMPSs this way, one diode per PSU and common buffer capacitor.
The diode can be one diode connected in a bridge rectifier, those are cheap and can work with high currents.
