Yep Martin your understanding is perfect.!!

These type of Kits are one of the worst Gotcha's I see new folks get stung with.!! Those drives are 50Vdc and the motors are easily capable of handling well above 50Vdc, 65-70Vdc is common. So the up shot is that any machine running this system with 36Vdc would be running motors working at nearly half the voltage they are capable handling. Speed of a stepper is proportional to voltage and very important for good performance so the system will be working minimum 48-50% less than motors are capable.
Also even if the correct voltage for these drives was used, 44-45Vdc then the motors are still working approx 35-40% less than capable.
