How to use multiple joints

I'm trying to build a part that will rotate slightly until the teeth dig in and the gears start turning. Is there a way to make both a slider and revolute joint work together? I attached the F3Z file below for reference.

The assembly is attached.  I introduced a hidden component to carry the Revolve joint from one component and carry the Slider joint from the other.  I then added a Motion link to approximate the when the teeth engaged.  I broke the file external link in order to send a F3D file back to you.

How did you get the new component in and deactivated? When I try to replicate what you did it just grays out my original components and I cant select them for the motion link.

I think the problem was my settings had "Active Component Visibility" off. I'm not sure though why my timeline looks completely different though. Yours has all the steps while mine just shows the new component being made.

Your model was just fine except you had a wrong value in your Motion Link.  You had 8mm travel for 180 degrees.  The circumference of your tooth diameter is 14mm so 14 X PI = 49.9823, which is the value to enter in the Motion Link.  Also, you must manually position the teeth, such as they are, and Capture Position BEFORE creating the Motion Link.  I will not attach your assembly because the only error is your Motion Link math.

Are you all set now?  You did not respond to my last post so I am assuming you are good to go.
