help please with toroidal transformers selection

[Tom J]

For a read of the how/why behind choosing a toroid based on steppers, have a look at my post in my Triac retrofit thread - http://www.mycncuk.com/threads/10344...5703#post85703

Although having just skimmed over the post, I've just realised I never mentioned about sizing the capacitor. It's a 100V 22'000uF from a reputable source.

That kind of answer I was looking for.
33VAC - 52VDC, big boost over calculation, any idea why was like that?

My both 420VA & 720VA has 30VAC and gave 41.5VDC (calibrated Fluke 87V and 1587)
Secondary coil was ~32VAC


picture shows Amp meter after calibration, voltage was set too
