Reduced mass "direct drive' extruder with frame mounted motor

· Reduced mass "direct drive' extruder with frame mounted motor
Ideas are flowing in.
A superior option to the bevel or worm gear might be to use the same timing belts we already use, but with a twist ( i mean that literally, not figuratively). This would virtually eliminate backlash from the system and would be much less expensive to produce without custom gears. Does anyone have any experience with running G2 timing belt (or comparable) with a twist? Perhaps it would wear the belts and cause premature failure?
Also, instead of a single X and Y cross shaft, multiple shafts could be used. The torque they transmit could be used for anything from extruding multiple filaments, to swapping remotely stored filament/hotend combos.
Edit:
Another idea,
instead of using expensive ball splines, perhaps precision ground square stock could be used. The linear motion would be transmitted through small cartridge bearings rolling axially, along the shaft axis. Since the shaft is square, torque would be transmitted tangentially through the bearings into whatever housing they are mounted on.

We’re looking for active users of Cura and Digital Factory — across professional and educational use cases — to help us improve the next generation of our tools.
Our Power User Research Program kicks off with a quick 15-minute interview to learn about your setup and workflows. If selected, you’ll be invited into a small group of users who get early access to features and help us shape the future of 3D printing software.
🧪 What to Expect:
A short 15-minute kickoff interview to help us get to know you If selected, bi-monthly research sessions (15–30 minutes) where we’ll test features, review workflows, or gather feedback Occasional invites to try out early prototypes or vote on upcoming improvements
🎁 What You’ll Get:
Selected participants receive a free 1-year Studio or Classroom license Early access to new features and tools A direct voice in what we build next
👉 Interested? Please fill out this quick form
Your feedback helps us make Cura Cloud more powerful, more intuitive, and more aligned with how you actually print and manage your workflow.
Thanks for being part of the community,
The full stable release of Cura 5.10 has arrived, and it brings support for the new Ultimaker S8, as well as new materials and profiles for previously supported UltiMaker printers. Additionally, you can now control your models in Cura using a 3D SpaceMouse and more!
