@ElmoC, no supports used. Just print. @MechaBits, yes I like it as well. Thinking of interesting models to mutilate with it. I have a female body somewhere that might be good. Perhaps I will do it to a Nimble stl and see what happens there. Using a Nimble to prove that the Nimble is nimble in retraction by printing a Nimble. Lykleby Lykle - General
What, you want the stl? Hmm, sorry can't do it. The license of the 3D Benchy does not allow derivatives of it. So yo will have to make it yourself at the Voronator site Lykleby Lykle - General
River of molten plastic, what a lovely way to put it. Could be. Again, I was simply switching filaments and had only paid attention to the first layer when setting up for Ninjaflex. I did not use different profiles for the different prints. As to more challenging prints, besides the lovely blocks. I printed a Voronoi 3D Benchy, right after I printed the normal one.

The object of the exercise here was to change as little as possible just to show it works straight up. Sure it was an easy test object. It is my default object to do a quick test if I change anything. At one point I had about 2 kilo's of these little blocks in all different materials. Threw them all away. Pity in hindsight. I could have made a wall mosaic with them.by Lykle - General
Interesting discussion! In the mean time, I went and made a video. The Nimble printing 4 different materials in the same setting. The only thing I changed is the temperature and in the case of the Ninjaflex I also changed the speed. So none of the settings were optimised for the different materials, only temp was changed. In fact is some of the prints you can actually see the previous filament iby Lykle - General
No, we are not worried. First of all, correct there is no way to adjust the clamping force. None is needed. There are two reasons for that. 1 We found a sweet spot in regards to pressure and hobbed wheel shape. 2 We engineered a certain amount of spring into the shape itself. It handles variations in thickness and type of material. We worked hard to avoid any flex in the system, as we want to mby Lykle - General
You say the resolution must be as small as possible, but that doesn't say much. What resolution do you need? As Z is not an issue, you are more talking about the plotter than a 3d printer. Right?by Lykle - General
@MechaBits Correct, the prototypes are Shapeways parts. The production parts will not be. We will add all the available adapters to our Shapeways page as well. People can choose how to get the adapter, download and print it or have Shapeways do it. Most of the adapters will be added to our website as well as STEP files, to allow people to edit and change them where needed. I say most, becauseby Lykle - General
Hey all, Just a quick announcement. We will release an Open Source Nimble after we have a successful campaign. We made it a stretch goal. Lykleby Lykle - General
Fun idea by the way! I like the way you think. Lykleby Lykle - General
Hi All, Just to let you know, there is a new Nimble today. It lost weight, 15% of it, and has a completely new breech loading mechanism. It also reduced in size. (I wish I could go on that diet) The new Nimble is the main reason we didn't have many photos or videos available, as we were working on this beauty. Now that we know we have it right, you will see a lot more photos and video appearinby Lykle - General
Pricing has not been determined yet. It is a bit too early for that.by Lykle - General
Print it in Vase mode, embed it in sand and pour molten aluminium in it. Presto, nice alu part. I did this a few times. OK, not in vase mode, made a model, stamped it down in casting sand and made it that way, but the lost wax method does work. Lykleby Lykle - General
We just announced that one of the add-on's we are developing for the Nimble is a filament sensor that will clip onto it, We are developing it together with David Crocker. We had a discussion about the remaining filament and by positioning it where we do, the last end of the filament is still available to be pulled out. Another advantage of the breech system. The design will be done in such a wayby Lykle - General
One option would be to look for SLS firms. Like Shapeways, but there are others that deliver at a lower price. I do not have any experience in the quality of these companies. Lykleby Lykle - General
I just placed an STL file of the Nimble on our Thingiverse page. But that one is a bit too "blocky" for you, because of the angles, so tomorrow I will send you personally a slightly better model that you can use. Only for you. :-) Other news, Since we reached 100 backers today we felt the need to celebrate. We announced the first add-on to the Nimble. It is a filament sensor that clips onto tby Lykle - General
Yes, the extra shroud is mainly to create space for the fan But In your case Deckingman, after looking at your files, I think the Nimbles will fit on your carriage without adding another shroud. So it will be simpler for you. And a lot lower that the projected solution. Unless you want to reduce the size of the X carriage, then we need to look again.by Lykle - General
QuoteMechaBits was just wondering if something additional in there could improve things? also surely the injection molded one could be different / smaller ? slightly different as its not 3d printed Correct, we could do inserts, but lucky for us that was not needed. The "forks" as we call them are more than strong enough, especially because we are using fiber reinforced material for the body. Ofby Lykle - General
Lol, curtains. Sounds like the voice of experience talking. I personally use an old toothbrush. Looks a bit crappy, but does the job and is surprisingly easy to clean. Alternative, I have seen people use those little copper brushes. The small disadvantage I see in these two, is that they do not scrape the molten filament off, the take most of it off and spread the rest around.by Lykle - General
@n8bot, the reason I stated surface area was because there was a concern over the Nimbles encroaching on the flow area. @deckingman: Yes agreed. I will do a flow analysis of the air in the chamber. It is amazing how sometimes little adjustments make for great improvements. Because the air enters the chamber already swirling, I don't think the Nimbles will block the flow to the heat sinks.

@deckingman. The more detailed look of the shroud for the fan give me the following figures. The overall surface area of the fan is 1930 square mm. The overall surface area of the opening at the bottom of the shroud is 1650 square mm. That is actually more that the surface area of the shroud designed by Reprapme. There it is 1590 square mm. The nice thing with the shroud as designed is, that itby Lykle - General
@Origamib. The overall weight of the unit now is 33 grams, that is including all the screws needed and the Groove mount adapter. On my Delta I have it screwed into an aluminium plate clamping the hot end in the process. The overall weight will drop once we manufacture the actual production units. @Deckingman. Yes, that is a relevant point. I made an overall assembly to analyse this and will contby Lykle - General
A couple of meters! What in earth are you planning! But yes, I could make you a one-off for that. Would be a slightly different drive cable and sleeve. Hmm, let me not make any promises I cannot keep. Let me investigate first. Lykleby Lykle - General
Nice work! I am really impressed how quickly you can do that. I would really struggle in Fusion360 to do this. Overall shapes are simple I know, but still. Here is a quick render of my Diamond nozzle mockup I did in IronCAD. Lykleby Lykle - General
If you want to measure correctly, you should measure the filament, not the rotation of the extruder. That way you detect all issues there are, blockage, break or run out. In order to make sure you register correctly, it makes the most sense to measure as close to the hot end as possible. The most simple way would be to use rollers, as they are measured easily. I have seen various limit switchesby Lykle - General
Hi All, Overall post to discuss the Nimble JamesK's question on drive cable length. Of course we can supply different drive cable lengths. My main test bed is a Delta of 1 meter tall and 32 cm print bed. The cable I use is 91 cm and that it long enough. For production, the drive cable is spec'd to being 95 cm. One thing that could help you, is if you can position the stepper half way theby Lykle - General
Hi JamesK Shall we move this discussion to a separate thread? Lykleby Lykle - General
I still wonder at the things I read here and marvel at the wisdom and humor shown. For me, I wish I still thought about design with childish abandon. Quite often they are the best ideas. For now, I am thinking of a new hot end idea. Will need to do some tests before I start sharing here. See if it is even possible. But simply too busy at the moment with the Kickstarter campaign to dive into theby Lykle - General
