    I've had a lot of streaking, mottling, and edge density problems so far.
    In the meantime, I learned how to use Jobo Expert Drum and Motor Base in this forum.
    I made a drum supporting device like this.
    And I developed several times with XTOL, and the scenes with a lot of clean skies were developed very evenly.
    I got a lot of information from this forum. thank you!

    p.s. When the 3010 drum is filled with 600mL solution and turned on with the original 12V/1A power adapter, the speed in one direction is about 20rpm and the speed in both directions(2 forward rotations, 2 reverse rotations) is about 18.5rpm.

    I also made a flexible funnel stand according to the picture above link.
    Thank you for your idea and advice.

    That second device is the part of the “system” usually missing when people put expert drums on their own rotation devices.

    A while back I rigged up a similar tank filling device.
    1. Having the handle to the funnel is a great idea since I had to use a round wire funnel holder and the funnel was only held in place initially by gravity and it easily moved when adding liquid to it.
    2. I found that the end of the tube going into the tank had to be cut at a downward angle with the hose entering the tank horizontally. If the hose was cut at a right angle, the liquid would easily overflow. Probably has also something to do with the I.D.. of the hose used.

    In the end I went back to filling and emptying the JOBO manually as I have always done since the early 1970s... old habits die hard.

    How do you like the B's Processor?
    I was considering getting one as a back-up or travel base since it's much smaller than my Simma-Roller.

    - As I wrote above, empty drum(big drum!) rattle a bit when changing direction of rotation. However, when the drum is filled with solution, it rotates stably.

    - If you use an adjustable AC/DC adapter, you can speed up the rotation a bit. B's Processor developer said 15V max would be fine.

    https://www.aliexpress.com/item/32959494100.html
    I tested the output of this adapter with a multimeter.
    11.9-12V → 11.91-11.92V
    13V → 12.9V
    14V → 13.87V
    15V → 14.89V
    16V → 15.91V
    17V → 16.84-16.85V
    # The measured voltage of the 12V/1A adapter of B’s processor is 12.32-12.34V.

    - B's Processor offers three speeds. When the drum is filled with 600 mL of solution, the bi-directional(2 forward rotations, 2 reverse rotations) speed of Mode 1 is approximately 8.5 rpm, Mode 2 is approximately 5.5 rpm, and Mode 3 is approximately 18.5 rpm.

    - If the drum is filled with 2,800 mL of solution and turned on Mode 3, it takes about 3.5 seconds to complete one revolution.

    - Of course, you can use the B's Processor in one direction as well. It speeds up a little.
