Create slider joints on two parallel shafts

SGoldthwaite — Sun, 21 Jun 2015 01:28:26 GMT

I'm trying to create a slider joint on the Z-axis of a desktop CNC model I iimported from Solidworks. There are two parallel shafts and a lead screw for the z-axis. When I make a slider joint on one of the shafts, the z-axis head rotates a bit, but that kind of makes sense since I haven't constrained it to the 2nd shaft yet. But when I try to add a slider joint to the second axis it fails. What's the best way to do this?

Sliders only have one open degree of freedom, a slide along the shaft.
Change the constraint to cylindrical, so that is can slide AND rotate.

Cylindrical joints have two open degrees of freedom, translation and rotation.

Thanks. I made the two joints cylindrical and now it works.
