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.
Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
