Hello guys,
I built a 3D printer that is currently running off the +12V rails of two old computer PSUs which is annoying with all the colorufl cables falling out and the space they are using. The +12V are going to a few microcontroller boards which all have their own 7805, 4 stepper motors and a heated bed which is basically a resistor printed on a self-etched board.
So I was thinking about building a PSU myself but apart from standard 78xx PSUs I never did anything in that league. Do you think it is enough to simply take a toroid transformer, 4 diodes and a few larger and smaller caps? Or will the ripple voltage confuse my motors? I think the 5V regulators should be fine with non-perfect 12VDC and the heated bed of course too, it should simply heat up but I don't know about the motors...
Or what would be the way to go for such a large +12V regulated PSU? A switched power supply?
Very eager to hear your thoughts!!
Thanks!
