Flexible shaft drive bondtech gear extruder anyone?

My new toy:

The NovaPro Mk II Flex cable edition is a remote drive extruder using a 40:1 gear ratio main drive with a Bondtech gear 3:1 final drive. It will be driven by a gantry mounted NEMA 17 moons motor mounted up near the filament pivot. A dual extruder variant is in the works.

Very cool!
Subscribed to keep an eye on this.

Neat, I’m looking forward to seeing the dual extruder version.

So it’s a Zesty Nimble with bondtech gears

An open source zesty nimble with a complete build at home parts list once I’m done with an existant taz mount and bondtech gears.

Motor mount now exists. This one goes with my backbrace mod. There will be a dual motor mount variant and a conventional 90 degree mount once I get further along in testing.

next up, the motor end of the cable cover holder thing.

Now the motor mount and support bits exist. Next up, extruder mounts then testing on the taz

Looking good!

Ok, this has progressed to the point where its probably time to have others start looking at it. Many files incoming.
