M4x Oops, didn't see your post until now. I've had to move away from FreeCAD for commercial work because of issues regarding parts assembly. I was using FreeCAD 0.20.1, from the official downloads link. The spacenavd is the latest version available on Ubuntu 22.04, and my upgrade to 23.04 hasn't br...

you have to create them within the body

Oooooooh! That's what it was! I didn't realize it was creating a different type of object depending on whether or not the body was active! Thanks for clarifying that for me!

Thanks @jackfreecad, I will try the pocket trick.

I had the gear in a body while doing my tests, but will let you know how it goes.

Hi jpg87 jackfreecad -alex- , Sorry I've been working on more urgent matters than this part of the project for the last couple of months. Thanks for all the detailed information - I'm digging back in and trying to get something to the point where I can fit it all into a working design. It's very tim...

Ok, finally! I figured out the issue of why it works with sudo and not with the service file. I believe this was true all the way back to older releases as well... When running spacenavd with sudo, it inherits the current DISPLAY and XAUTHORITY values from the user's session. The service file, on th...

I realize this is an old thread, but I've been fighting to get my refurbished SpaceExplorer (with the 16 buttons on it) to work right for me on Ubuntu 22.10. I ran into the same issue as M4x - if I depend on the service (systemd in this case) to run, I get the 6 DOF, but the button mapping defined i...

Merci Alex! Edit: if you read french, have a look to this document from page 298 (especialy page 302 for conical gears): https://fdocuments.fr/document/guide-du-dessinateur-industriel-chevalier-ocr-sommaire-pdf?page=298 I'm bilingual, and for some reason didn't think to look at french documentation....

I think, from what I understand, that the positioning is as you show:

Cone centers match.
The angle of the triangles match - that's why we cut above and below the teeth, but that middle line matches up between the gears?

Happy to be corrected if I'm wrong.

in reality in my example, not only the flanks are at an angle In this example of the pinion, the projected angle between flanks at the pinion is 5.28 degree in reality less because of 3D I realize that. But if you put it flat on the back, it's still something you can cut with a standard mill, there...

I made a assembly 4 withe the ring and pinion get it here:https://drive.google.com/uc?export=download&id=1U_7cbtmnjdIgKGR_anEhthxFOzknsqDH and can be animated with variable move I am not mastering the LCS in 3D but it is close the meshing does work apparently with 12 teeth without undercut Edit...
