I have started to use pre programmed routines, I can also programme my own routines if I want to. Downside for the robo pong 2055 is only 1 spin type can be used.
there is also a ‘random’ option, you can select the ‘spread’ or ‘oscillation’ as they call it, so I use both extremes as the max left and right ball placement, then the robot fires the balls at any position randomly, this is very good, especially when you have to adjust your position for balls that are fairly close to the previous ball, small adjustment rather than static and stretch.
if I want a lower ball, then I use a long serve ball feed, good for loop openers v backspin.
