Anything about the Dm542t or Dm542a???

Well 542 will be a step up from TB boards and 50V gives a fair performance. Next step up is 80V and lots of builds end up here but you would need 80V drivers

Motors don’t run faster at higher voltage (you control the speed with the feedrate) but they run out of torque at lower voltages which limits the range they run up to without missing steps.

To help with this you run at higher voltage and to help further you need motors with lower inductance. 3mH or less is recommended. Inductance is resistance with phase (someone correct me). That is why we don’t recommend kits as the motors can be high inductance.
