    I have two of the latest Nimble extruders. One benefit that is somewhat obvious in this video is how incredibly small it is. Two of them will fit on the top of the E3D Chimera+ with a very basic mount. Regarding torsion from the cable, it is running a 30:1 gear set and like any extruder you simply fine tune your settings. Have used ABS, PLA, PETG, TPU with zero issues of feeding.

      I have the same set up. Eventually gave up on the Chimera though, mine was the original, too narrow and it was forever blocking, jamming etc. Put me off E3D for life. Moved over to a Crealty CR20 and never picked up the Nimble again.

That is in addition to the VAT we probabbly have to pay to Australia (or are the prices on the website without VAT?). So technically we don't pay "customs" but still need to pay them around 30€. All in all total cost is around 130-140€.

    You know the main thing that drew me to wanting to try this product out right after seeing it for the first time on this video is that it removes the wight from the X Carriage. I made a Clone Prusa which I named Birchy for the birch plywood frame :P and one of the problems I have had was the weight of the X Carriage. I have been fighting artifacts from it for a long time. Its not the most precise build and I have been constantly modifying it and experimenting with it to try and make things better. One of the main issues were the motors that I had originally purchased were pretty heavy in my opinion. I had purchased lighter ones but I eventually stopped trying the Direct Drive designs for it and moved to a Bowden design which helped a lot. It prints pretty good now but there has always been room for improvement for that printer. Hopefully this Nimble Extruder will be just another improvement to it in a line of improvements I have made to it already. Can't wait to try it out. :)

    This looks almost identical to the Flex3Drive that's been out for a couple of years. I hope the Zesty product uses a better driveshaft because the one in the Flex3Drive (also a cable drive) reportedly gets sloppy after a while and causes feed issues.

    Beautiful concept (taken from motorcycle speedo cable or flex shaft die grinder?)
    I see a few issues. 30:1 means stepper must spin damn fast to get the speeds you want. Fast retraction would be iffy. Missed steps will be an issue. 3 to 5:1 is more than enough, since most extruders are 1:1 (gear on motor shaft) and function quite well past 150mm/s print speeds.
    With that high ratio, why only 1 gear drive? Dual with 30:1 makes more sense to me especially with slipperier Nylon.
    Secondly, lube. Are the gears being lubed? I see sealed bearings. As with all gearboxes, it will need to be taken apart and cleaned out of spent lube. Hopefully it doesn't ooze out somewhere. Maybe make gears from igus material and you won't need lube. In that aspect, you could remove all the bearings for igus bushings.
    I like the pressed-in threads. Good touch.
    He said speeds on volcanoes are 'reasonably fast' and not 'insanely fast'? 30:1 is the problem. Sure, doing 1/4 or 1/2 stepping will lower your step count and give your tiny 8-bit machine breathing space but then it is a give/take for accuracy vs speed.
    Thirdly, the straight cut gear. Backlash in a worm drive is lowered(eliminated) by bevelling/arching both gears and 'sinking' it deeper into each other, providing higher teeth engagement. Check the pic to understand what I mean: www.amrutgearsindustries.com/gears/worm-gear/industrial-drive-worm-gear-worm-shaft.jpg
    Does this setup accept off the shelf extruder gears?

      @@guillep2k On either my Delta or my Cartesian machine, retraction is the same amount. I see no reason to draw back more with the Delta over the direct drive Cartesian machine. Both are driven with 1:1 extruders. They both have the same step/mm count and are within 2% of each other.

      @@leofortey7561 It's not about delta vs. cartesian. The benefit of Bowden is that it allows for more speed than direct because of the mass difference (by taking the heavy motor out of the equation). The disadvantage is that you have less control on the nozzle pressure and you need more retraction to avoid stringing (and it's very difficult to drive softer filaments). Just Google Bowden vs direct.

  • @badstep495

    just keep in mind that eventhough the extruder is light, the drivr cable is very heavy and stiff, thus it does cause a lot of torque on the hotend and adds more weight than just the hotend itself. I have one and while it works well, there are clear disadvantages as well.

    Video Idea: ultimate FDM speedtest using Nimble + SuperVolcano + beefiest stepper motor you can find (maybe a chance to try Trinamic TMC 5160s at the same time for higher amperage?).
    Either way, this needs a proper review. Have been looking to move to Direct for my CR-10 for a while now, and between the ease of upgrade, weight benefit, and (hopefully) elimination of traditional Bowden issues with material type and retraction, Zesty just pulled way ahead of the Bondtech BMG I'd been looking at.

      He actually mentioned that in the beginning of the video. They're using a specialized flex cable that is equally stiff in both directions of rotation, plus it's running through a 30/1 gear reduction, so any small amount of torsional flex in the cable will be dealt with when you tune the extruder initially. It's really a clever idea.

      @lacucaracha111111 5 ปีที่แล้ว +1

      @@ChristopherGoggans can you even tune rotational directions seperately on an ender 3 or CR10 (as shown in the video)
      And such a flex shaft cant really exist physically one side will allways be somewhat weaker (often the inner spiral as the outer gets supported by the inner on rotation) not to mantion ongevity and wear resistance as a flex shaft is a guided springwith contact on the windings (when straight) a "bi rotational"one is just 2 inside eachother.
      To give minimal deviation betwen CW and CCW you would need to have a perfect material difference and very tight tolerances on the guide making bending hard or very abrasive at the bends. The conclusion would be to use high grade materials once again.Making the upgrade something only enthusiasts would use. Enthusiasts with machines allready way better than ones benefitting from that upgrade.
      And the people benefitting from the upgrade would shy away due to price.
      Or option 3 still not direct drive extrusion, but better than bowden. A swiss army knife; do it ok, just not perfect.
      That is the tolerance of the flex shaft, ontop comes the one in the drive reduction gear and if one thing is true in engineering, its that tighter tolerances= monney spent

    This is the pinnacle of extruder tech today. A Nema 8 motor. It's about 20mm square. This is a staple in the 3d printer technology. Of course a nema 8 will have limitations but we're not limited by size and weight anymore. We can use a nema 11 with correct gearing for speed and quality, extruders are getting smaller every day and will eventually combine with heatbreaks when micro water cooling becomes more popular for high heats. 300mm/s printing will soon be possible for the average joe. Shopping is about to be changed forever. In 50 years when 3d printing can print ceramics and glass, malls will be online only.
