I am currently trying to implement a carriage on a lead screw, but it keeps rotating about the translational axis. No documentation I have been able to find addresses this. I have tried to resolve this by constraining it with a slider joint, but this results in an error in the build.
Thank you in advance

It's rotating about a wrong axis? sounds like you need a rigid transform block in the middle to align the rotating axes.

I recommend you look at this example:

One of your parts should be constrained so that it does not rotate. In the model above, both parts can rotate about the translational axis.
