ROTARY DEVELOPMENT: Uneven development : Xtol 1:1 / Jobo 3010 ???

This is true and yet 1000 ml as a single step is probably hard on the motor regardless of the version. Breaking the 1000ml into two evenly timed 500ml developer steps is no more difficult and puts way less strain on the motor and circuitry.

Everyone wants to help you, but no one is addressing your real problem. You are using your Expert Drum in a way that was never intended. You are also fabricating processing times and procedures that do not correspond to any established methodology. God knows what else you are doing incorrectly. By dreaming up your own darkroom practice, you are, so to speak, shooting yourself in the foot--perhaps both feet. I suggest that you (1) buy a Jobo processor (with lift) for your drum, (2) read Jobo's manual (which is filled with good, reliable information) cover to cover; and (3) follow Jobo's instructions to the letter. When you follow instructions, the problems that you have created will magically disappear. If you cannot afford a processor, follow the standard times and methods for tray processing, or find and follow another standard established film-processing method.

even you just develop a single sheet of film, you need to add minimux of 300 ml developer and other wise you could end up with uneven developed film that is my experience.
