work-in-progress: double driven feeder

[ataraxis 51]

hi!

i am working on a double driven extruder as mentioned here:

https://ultimaker.com/en/community/view/16960-does-anyone-already-have-installed-the-bondtech-extruder-feeder

i will update this thread from time to time, this is my first model:

some information to understand the picture/model:

all the components (gears, pulleys,...) are fixed on the shafts.

every shaft rotates in an ball bearing, except the rightmost one, this is the one from the stepper motor.

the timing belt will be tensioned by an jockey pulley - this allows you to change the the distance between the two drive gears (e.g. for flexible filaments, 3mm filaments and so on).

so long... i'll be back

Cool. I briefly tried designing something similar a while back that I wanted to be printable. But designing gears as small as I wanted them proved to be difficult so I never got much further than the idea stage hehe. Looking forward to see more.
