Rack and Pinion part 3 - Adding Joints and Motion

[@davidstonier-gibson5852]

Thank you. Very nicely done. I particularly appreciate your choice of background music.

Thanks for this series. I have had the problem of controlling when bodies join or not. You explained it clearly, now I know.

You're welcome!

[@louisnguyen6038]

that was a great explanation that touched upon many different techniques! Thanks

Excellent series, really helped me with building gears for my project

[@DesktopMakes]

Great to hear!

Great tutorial. I thought of maybe a slight tweak to the design to make things fit better together and print. Maybe changing the join between the frame and the peg. Change from a circle to a triangle join. Just so the frame prints better as the circle might distort too much printed up right. Anyway just a suggestion.

I'm not sure I understand. How would the gear spin if the opening is a triangular shape?

[@brendanowen7563]

@@DesktopMakes Hello sorry I miss understood where the spin was happening. I assumed it was spinning between the "peg" and gear. I see now I was wrong, the spinning is between the frame and "peg". Yes a triangle would not spin.

Hello, I am designing a rack and pinion mechanism but at a much smaller scale. The total circle diameter is about 0.58”. I had to create a custom gear that allows for it to be machined on a cnc as it needs to be made out of titanium. My issue is that it does not contact exactly the same as the gear shown in the video. Is there a way to use the motion link in a way that only moves when the two components contact one another? Right now they move fluidly but don’t contact with the standard motion link

Yeah, you can try enabling Contact Sets but I didn't have luck getting it to behave smoothly with gears the last time I tried.
