Re: Power supply voltage.

Just a thought here, but are you measuring the AC after the transformer
?

once you rectify it and add your cap's, you will see a DC voltage 1.414
times the AC voltage.

that means your 83v would be at little high at 117.36 volts.

Your 42 volts would pop up to 59.39 volts.

All this may be acedemic if your steppers are not rated at between 3.3
volts and 4.1 volts.

As a seperate note, I think that there are more than a few guys on this
list (which is now approaching 3,000 members) that would pull a few
loops off the transformer to get 79.999 volts.
