Powered up steering wheel control - Help

[atomada]

Hi all,

Recently I bought an Powered Up Technic Hub (88012) and two L motors (88013).

The goal was tto have a simple car RC configuration where one motor controls the speed and the other controls the steering.

By some reason the one that I’m configuring for the steering, starts moving indefinitely. In the image is the configuration on the right. Sounds it should be easy, but perhaps I’m missing something. Or could be a problem in my new Hub?

Picture attached.

Thank you so much for any help!

Do you have the motors built into the car yet? The steering motor usually runs a calibration step first, where it finds its mechanical limits of travel.

Adding two pins in any motor holes for testing will do.

Hi,

I still don't have the motors built in the car (by the way, the car is a MOC of Fiat 500 which will become it a RC Fiat 500). I wanted to test the hub/motors before start the build.

The build instructions come a picture of the supposed configuration (picture jpg attached), and seems in line with my configuration i have. I understand that somehow I should calibrate to have the limits of travel, but I was expecting some "travel distance" by default when using the block at the right. I ask myself that despite I'm using two different blocks (the one I have in the left side and the other in the right), seems both have the same behavior (rotate the axis indefinitely).

Sorry by the lack of experience, and once again thank you for your help!

Thank you

No, because this routine is independent form the geometry or size of the model.

yes, insert two pins into the motor holes for testing. What happens?
