Wow, very impressive build. And nice to see Pybricks mentioned. How are you planning to control the two hubs and do they communicate with each other? This has been driving me crazy as well, I commented on it in the thread below as well. So far I only one (!) out of seven Z60 turntables that I own runs perfectly fine. Two mesh really badly with the 12T gear and the others are just not great either but okay-ish, sort of like what you describe. I am trying to figure out if this is a problem in older or newer sets. The thing is that 42042 is a set from 2015, and that uses a similar set up as yours. And I would assume it meshed fine back then. The Z60 beveled turntable gear was in sets between 2015 and 2021.

Same problem here. It could be that some Z60 turntables are faulty, but I doubt it since that should be fixed in the newer batches then. And many of them seem to have this problem. What I did notice is that it matters a lot how close the 12T bevel gear is pressed against the turntable. If the gear can move away from the turntable ever so slightly, it has trouble engaging with the next tooth. The margin is very small.. might need to put a small plastic ring or something between the gear and the part that holds it. I noticed that they use the H-shape lift arm (14720) in the 42042 set for example: https://www.lego.com/cdn/product-assets/product.bi.core.pdf/6151636.pdf (starting at step 32, page 87) Edit: Ok I just received a new Z60 gear and it _does_ mess well.. 🥴

Hi all, first post here. Made this using Pybricks, it's pretty straightforward but there is a neat little mechanism in there with two differentials that allows the vehicle to roll freely independent of the motor. Also programmed it so that the vehicle tilts depending on the speed and the steering angle. Because of the space the three motors and the hub take up, I didn't really have space for a passenger seat. Let me know what you think! while Button.B not in controller.buttons.pressed(): power = controller.triggers()[1] - controller.triggers()[0] steer_percentage = controller.joystick_left()[0] steer_percentage = 0 if abs(steer_percentage) < 5 else steer_percentage car.drive_power(power) car.steer(steer_percentage) if Button.LB in controller.buttons.pressed(): tilted_car.steer(-100) elif Button.RB in controller.buttons.pressed(): tilted_car.steer(100) else: tilted_car.steer(100 * (steer_percentage / 100) * (power / 100)) wait(10)
