corexy with bowden on top?
-
@matt3o Thanks for the info.
I have a FlexDrive kit but I have not tried it yet. It appears to be more complicated than the Nimble.
At one point I had five printers equipped with Nimble units and I was happy with the results.
Do you have a picture of this effect you are talking about?

@CaLviNx The nimble is not the only extruder based on flexible shaft + worm gear on the market. Not sure why you need to go personal on this, I already said I'm not a reliable source and that I haven't tried the Nimble (but I tried another remote-direct drive).
Again I'm confused ?
Please show me where is said that the Zesty Nimble WAS the only flexible shaft & worm gear extruder on the market ?
And As an engineer I was not getting personal (trust me you would soon know if I was getting personal) I was merely pointing out the fact that you are tarring all flexible shaft extruders with the same negative brush without having experience of them all, logic would then dictate that you do not base your experience on facts to say
<not very happy with the quality of "remote direct" drives. Mostly the worm gear is not the most reliable of the mechanisms.
You should have said "I have not had a good experiencing with a certain brand of remote direct drive extruder"
And as i already stated above I would hazard to say you had a negative experience with the "flexdrive" extruder, I have one and it is terrible.

You can see an example here . If you try the flexdrive please let me know how it works compared to the Nimble. A friend of mine has both and he finds the flexdrive better (he says the flexible shaft is better built).

you are probably right, but for every 10 people who say that the nimble is better I find 10 who say the flexdrive is better, so at the end I guess it's not that objective (by that I mean that it probably depends on your machine/configuration and ultimately experience).

I bought the flexdrive before I bought the nimble I could never get the flexdrive to extrude properly, one minute it would over/under extrude even with the same settings.
I went to a nimble and it "just worked" I would like to buy more Nimbles but due to the current state of the world they are not shipping

Thanks for the picture.
How did you know what was causing that effect?
I'm currently testing a Dragon hotend and am still tweaking things but here is a recent test print.
Thanks.

literally months of trials and errors. I tried to replace every single piece of my poor little machine
(and still working on it, bowden is the only thing I still have to try)PS: I'm currently on a mosquito and can only say good things about it

This is one of my test cubes (for the extrusion multiplier) with the Nimble.
Ignore the base I like to print with a skirt attached so i cut that off

@CaLviNx looks very good from your picture. My texture was actually visible only in certain light conditions (otherwise it looked good).
I tried to "enhance" your picture to see if I could simulate those conditions and got this.
It's not what I expected but interesting nonetheless
Did you increase speed in the middle on the cube? -
I dont quite get why you "enhanced" my picture to show a pattern that isn't actually there, you can play with this cube under a light and no pattern shows up and no pattern can be felt to the touch or with a nail.
Unless i missed that you are trying to show the issue you had of course?
I printed this at a constant speed on one of my delta's
The pattern you have simulated is usually cased by a resonant frequency of something

Every extruder has a fingerprint, that is the one on your printer. I'm not trying to find the flaw, I was trying to see if the pattern was similar to mine, but it's completely different.
