Extruder's stepper - 1.8deg or 0.9deg?
-
@fcwilt, I recently saw a video about it, IIRC it was a MRRF interview. Very interesting. I cam currently stabilizing a new CoreXy printer but once it will settle down Zesty will definitely be on the short list.
My Bowden is 60cm long so I presume I need the Nimble 75cm cable, and will also need some loose ID PTFE tube for the filament feed.
How is it attached to the X carriage? Some holding screws or just being attached to the top of the hotend (e.g. V6)?

they are making all adapter available on thingiverse.

@veti, that's very useful, thanks. I do see mounting screws which is good. It's interesting that the use the sidewinder for the HEVO. I would think everything going up and tied together (extruder cable, electric wires and filament PTFE tube).

I recently fitted a Nimble feeding a E3D V6 to my FT-5. I designed and printed the mount.
I used a vertical Nimble and used the drive cable as a support for the wires going to the hotend.
I did not use any sort of tubing as a filament guide, I just feed directly off the spool. A tube might be a good idea.
After I got Nimble up and running I decided the mount would be a good place to add a pair of fans for part cooling.
As I type I am printing the parts involved in that.
Attached is a picture of the experiment to see how a part cooling fan would work before I undertook modifying the mount to accept the fans.
Printers: A FT-5 with the 713 upgrade bits, a custom MarkForged style, a small Utilmaker style, a small CoreXY from kit and a E3D MS/TC setup. Various hotends. Using Duets (2 and 3) running 3.4.6

in toms mrrf video they said they will design an adapter for every printer. you just have to contact them.

@veti They even have an adapter for a Titan Aero! ROFL!

I do remember hearing that.
I'm fine with designing my own parts.
Adding the fans led to some conflicts with existing original parts of the printer. I had to work out a fix for those issues which led to designing other parts.
Great fun when it all comes together.

What kind of a stepper do you use for the nimble? With the 30:1 gear ration I presume that a small pancake 1.8deg stepper is more than enough.

I would imagine. I just used what I had on hand - nothing special - a typical 1.8 stepper.

I tried installing a half length 0.9deg stepper but the one I got didn't have a flat side on the shaft, shaft was barely long enough and the depth of the 4 mounting screw was not as deep as a standard stepper. Will get to it another time. It looks nicer though on my printer than the full size stepper.

+1 for the Nimble. Been using it for a while now and it's working great...
It's a little hard to see but that's because it's so small. It tucks right between my hotend and part cooling ducts,
