I got another question, I never really thought about it but should I be buying 3 power supplies instead of using just one? The reason I ask is that I just notice in a lot of the pictures on here, the prepared kits people buy online typically come with 3 power supplies, one for each axis. I'm just not sure if there's a greater purpose having the 3 instead of just using one if it still meets the required amperage and voltage ratings for the motor and driver.

The power supply I have is 20 amps, and 24-26 vdc, I'm buying the dm542t motor driver which requires 20-50 vdc. Also I have 3 nema 23's each 3amps. I know I can be using a higher rated power supply (closer to 50 vdc) for optimal torque but if it's not a problem to use only the one, I think I'd stick to my 24-26 vdc power supply.

In short;... is it a problem to run all three axis' on a single power supply if the power supply meets the requirements of the motor driver and motor? And is there a reason kits sell 3 power supplies instead of just the one?
