Hello,
My fish feeder, the Grasslin Rondomatic 400, stopped working (I couldn’t hear the usual low buzzing sound). When I looked for information, it was mentioned that this issue can be caused by fish food getting clogged inside. That was indeed the problem in my case, but what wasn’t mentioned is that the gears can fall apart when the unit is disassembled. Now I’m struggling to put everything back together. Unfortunately, support has been unresponsive. Is there any chance that someone has gone through a similar issue and might have a guide on how to reassemble the gears?
 
I went through an issue like this many years ago. There was no help and it was either be mechanically adept and get it back together perfectly, or accept the loss. I no longer have one...
 
I didn't know what one of these was so I searched online out of interest. One of the first things that came up was this video. I'm not sure how much of the mechanism is actually shown nor what the video is trying to achieve, but it might help you.

Me too. ;) Here is what I came up with as to gear placement.
