Stepper Motor Pivoting Arm Help

infoS4R27 — Tue, 02 Dec 2025 15:43:16 GMT

Hi, I'm trying to build a model of this fuel probe for a flight sim. The probe need to lift up and down (pivoting on the main pin, joint 1). I've added the cylindrical joints but how do you make them all stick together at the same time? All my joints seem to only be connected to themselves? Thanks!

Hi,

What you probably need here is a Motion Link to define what happens when you move

one joint that affects the other. It is commonly used for such things as Jack Screws

where the screw rotating makes the joint move up or down. I would imagine that in

this case as the bracket moves forward or back that the arm rotates up or down.

Good luck.

Cheers

Andrew

Do you have original geometry before it was converted to stl?
