Which mate to choose?

benedikt_hartweg

Dear Onshapers,

I need your help on this matter. I cant seem to find the proper mate for this application.
Please see the pictures attached below. I want to mate the wheels of the gantry cart to the v-shaped extrusion (based on the openbuilds system). I already tried the "normal" mates, like the slider edge using some edges and also the tangent mate, but they just wont do the job.
There´s no need for the wheels to actually turn.. I just want to be able to move the cart along the extrusion.

Many thanks and take care,

Ben

Slider mate will be the one.  If you share your document, we can help more specifically.

I suspect you are having trouble with offset of mates.

The document is not public - please see the instructions for making public and copying the URL.

Also - it would help to have your 'broken' attempt at Mate and create a version so we may review even if you change document.

Defiantly slider.

Either you can do it with an offset in place.
Or you can create a mate connector in the sliding plate partstudio that has the offset, then add slider to that.

All slider constraints should be done defiantly
