Has any one used a transformer from a microwave, cut out the high voltage wires and rewound it with some 14ga or 16ga.wire and put a ful-wave bridge rectifier on it with some caps on it and built there power supply for there cnc stepper motor drivers.my 24 volt.power supply died.Just got this used with some small steppers,and a small cnc engraver,so now i need a power supply.I have an old microwave that i removed the door switches and used them for my home switches on this,so i have a transformer to use...thinking about 30 volts at about 10-15 amps would be enough.
