I was trying to make a planetary gear set without a chain but what ended up happening was that the motor that spins the carrier didn’t change the speed and also didn’t contribute any speed to the final outcome. But might contribute torque but I don’t know how to test this. [image] [image] I’ve a…

[image] weilin: This is not how it supposed to work. The direction of rotation for the 36t gears needs to be opposite, and you have them rotating in the same direction. You will need an even number of 12t gears between 36ts, like this: This touches on why the gearset doesn’t work, but isn’t …
