I have a 3dConnexion spacemouse, probably an older model though, I’ve had it for 6-7 years I guess. It does work in Bambu Studio, but it doesn’t work well. The sensitivity setting is so low, it takes way too long to turn and zoom. The device comes with some software where you can configure sensitivity settings but for some reason they have no effect in Bambu Studio.
Great when using with Fusion 360 or other CAD or 3d modelling programs if you want to make your own 3d models. I don’t think it’s worth it for Bambu Studio, unless there is some way of increasing the sensitivity that I don’t know of.
