power supply problms

Ok, it is most likely getting hot.
Have you tried adding a fan?
But it is most likely better to replace.

might try a fan

i will have to think about a new power supply as i might change out the stepper on my rotory table
and replace it with a servo

Two things to check...Leaky capacitors,you know when they're leaking a bulge occurs in the top of them.

Other thing is dry joints,these dry joints register ok when no power is pulled and occur when power is pulled.
