Thanks!

Thanks a lot for your nice comment!

Thank you!

Thanks Tomáš! The ball splitter is a design by Jason Allemann (JK Brickworks) and basically it simply uses a bionicle tooth, a 1x6 tile and gravity. Jason explains and shows how to build it in one of his 2020 marble run videos (link in the description). Indeed it works superb! Tried 2 other ball splitters, but they couldn't handle 2 balls that follow one another so rapidly as in this module.

Thanks!

Thank you! 🙂

You're welcome.😁

Good question! 🙂 Initially, when I rebuilt Akiyuki's version of the mangle rack mechanism, I also used just one M-motor and all worked perfectly fine. However, to turn it into a complete GBC module (actual balls entering\leaving the sliding hoppers/trays), I made quite some changes and this resulted in a significant increase of weight. Especially the 7 hoppers/trays contain much more pieces compared to Akiyuki's original design. Due to this, the black thingy that moves the hoppers/trays, together with a few other elements, had to be reinforced as well, increasing the piece count and weight of the whole thing even more. Well, to shorten the story a bit, at one point the single M-motor wasn't able anymore to do the job properly, so I tried 2 M-motors... then 2 L-motors... 1 XL-motor... eventually ending up with 2 XL-motors. Only the setup with 2 XL-motors resulted in the somewhat smooth movements shown in the video and only the 2 XL-motors combined could move around all 7 hoopers/trays with ease and with an acceptable volume level. Also, when testing different setups, I found out it's not only the increased power of the XL-motors that did the trick in the end, but also the fact they're placed opposite to each other certainly seemed to help. So I would say they're kinda necessary to get everything up and running in a smooth manner and if you're planning to rebuild this design, I wouldn't advice to use less than these 2 PF XL-motors, unless you're going to make a considerable amount of changes. Just my honest opinion based on my own experience gathered during the design/building process, of course you're free to experiment and try out other setups to see what works for you, but I can tell you my abandoned early setups were horrible to look at and listen to! 🙂

Thank you for this very long answer. I do understand all the reasons why you did it like these now. I am willing to build it anyway and so I need 2 more big motors. It might happen, that I will write more comments here just to have an idea how it works best. But it might take a few weeks or even month. Time is always what I need more 😁 Thank you again

@@thebigmg You're welcome! Will always try to help as much as I can 🙂
