Just built the cyberbrick forklift, for some reason the 360 servo won’t stop spinning. I tried the second servo in the kit and it’s the same. Anyone have any ideas? This noob would greatly appreciate any assistance!
Have you tried disconnecting and reconnecting the joystick on the controller assigned to the servo? Hint: It’s the single axis joystick on the top right hand side of the standard controller. Often, this issue is caused by loose connections.
Yeah, if the servo moves, it does because it’s being told to move. Disconnected from the receiver, but powered up, it won’t do anything. So if you can’t control the servo movement, but it moves, the issue is likely with the controller and not the servo.

Hey folks, thanks for the suggestions.im really enjoying the learning process. I’ve taken the whole thing apart (forklift and remote) and built it all over again. Same results. Out of curiosity, i swapped the single axis joystick and the rocker switch wires and it works as it should with the rocker switch. Position 1 goes up, position 0 it stays put, position 11 it goes down. It made me think i read the instructions wrong? I’m pretty sure its supposed to be the single axis joystick that operates it. Anyway, I’m having a blast learning. Thanks for all your help!
Hey chiz_m
It turns out it WAS the wire! Not a loose connection, but the wire itself. I kept looking at the dead zone setting of the joystick and (not really understanding what I was looking at) kept seeing a midpoint value around 4400. I didn’t realize I was looking at the live value of the stick! It was reading maxxed to the top when not being touched. Once I understood what I was looking at, I tried the other joystick in the kit, it read the same maxxed out value. The only thing left to change was the wire itself. I swapped it out and voila! midpoint value of 2200. It looks like my kit came with a bad wire? Thanks for your suggestions!
Hey DHC,
Not directly related to weighbridges, but at Griffith Elder we’ve worked with servo control in some of our weighing systems—especially when integrating automation into our single axle weighbridge setups. If your 360 servo keeps spinning, it might be receiving a continuous PWM signal rather than a neutral one.
Have you checked if the servo is getting a “stop” signal (usually around 90° or 1500μs pulse width depending on the controller)? Also, some servos need to be calibrated or may default to full rotation if no clear signal is received.
If you’re using CyberBrick’s preloaded code or custom controls, it might help to share that snippet here—someone might spot the issue quickly.
Hope that helps a bit!
I believe the 360 ‘servo’ are effectively gear motors as it doesn’t have stops.
