I increased my motors supply voltage by a cheap ebay step up converter from 12V to 26V. To do so I cutted motor supply pin to my ramps and fed it directly from above by wire. I have removed my diode protector boards because they have reference to my ramp's 12V.
Yeah... But unless you can supply serious current, that isn't going to accomplish what you want. The whole reason you drive the steppers with higher voltage is to push more wattage (power) to them. If this converter can't drive many amps of current, it is actually going to hurt you.
