That is the way to do it...upload sketch to bare arduino, then add the ramps, not while plugged in....turning psu on after usb connection is fine, if not the best way too do it, but it works both ways.
I had a little issue with my ramps setup last week, it was a bit of a pain to get every axis moving, in the end most of the issue was wrong cable on Z motor, changed that driver, and rewired the Y to get motor polarity & phase correct as that was a bare cable....but now it's all moving nice, it's on a ramps which was powering another machine till that had Z issues....I swapped it out... only to find the issue was a loose Z, so that may have damaged the driver I replaced, jiggling cables, or plugging in steppers shouldnt be done while on.
I also use Matter Control but because the driver of the arduino was an arduino driver...and for the life of me I could change it(i've done it before but its hit n miss) Matter Control Didnt recognize or instal driver....so I started Repitier which I never use so it wasnt configured but it could see the machine no problem and movement was quick to follow.
