i bought a 48V power supply off amazon (48V, 350W, 8A) to run my G540 with 3 stepper motors. i read some information from Gecko that they like unregulated power supplies because they absorb voltage sent back from the motors during rapid deceleration. do i need to worry about this with my switch mode power supply? if i put a large capacitor in parallel with it, would that help? I also read where Gecko had tested some cheaper power supplies and they were causing the G540 to pop because they would go to to high a voltage. is there anything i can proactively do to make sure that doesn't happen?
