Anyone knows where to get 0.35 or 0.4 nozzles? That fits the velleman extruder ofcourse.
Would be also interested in such upgrades.
would be intrested as well
BTW
Can anyone tell me what kind of thread the nozzle has? If I knew that I could make myself a smaller one.
Hi,
already made your 0.35 nozzle? Good results?
I have just ordered 2x .35 nozzles hope they will fit measured outside diam of spindle that holds nozzle is 5.97 mm.
I also ordered with shop in Italy a new hot end noticed that the white tube from Velleman is 3.44 mm and the one from 3drag 4.07.
Tried the new hot end and is working fine an advantage is that the thermistor is already fixed to the hot end.
It will only fit if a piece of filament is sticking out and then the two bolts are fastened and the filament serves as guide.

cool, let us know if it fits, i would like a finer tip to 
Grtz
The thread of the nozzle is not standard M6 / 1 … that would be the norm
its M6 / 0.75 … so the read of the nozzle is a bit finer
I have right now the problem that I wanted to clean the nozzle and the thread on the other side that holds the nozzle came appart … so right now I can not screw it back together because is doesn’t hold anymore
So I was trying to build a new “nozzle holder” and mine is not M6/1 it’s M6/0.75 … so the norm M6/1 is to big!
Hope that helps a bit.
The .035 nozzle has arrived (took 5 days from US to Holland) however it need to be fitted with a lot of force and I do not think I can take it off again or will damage the tread of the extruder filament guide pipe.
I will print with the extruder from 3 drag, which I am using now, and then the same print with the .35 K8200 extruder.
I do not know how to attach a photo
the 0.35 nozzle printed less then the original nozzle 0,5 mm there were also a lot of small treads when I printed a test cube with a hole in the middle.
The settings were for both the same and also I used the same green filament.
I think that dark colored filament is printing more easy then high visibility colored filament??
I read that lower temp (185) for the later solves the problem ?? to me these are difficult to print with?

I print with 0.35 on a prusa I3. (main reason for not using the 8200 anymore), but It is more critical to get it right!
You have to manualy tune the whole system, beginning with the feedrate e/steps.
The you have to go thrue the full calibration steps, and remember, because .35 is less forgiving, changing a roll filament can throw out all your calibration.
But once you get it right, it is a joy to print at 0.06mm layer height! (in terms of quality, not speed)
Just my settings, with pla and 0.35mm hot-end:
hotend 185/185 (this is on the low side, i go higher for technical parts who must be stronger, but the idealy one must use a closed cabinet with larger parts)
bed 0/0 (bleutape) or 60/60 on glass (but costs energy, bluetape is a lot less expensive)
first layer .25, other layers .06 or .1 or .2
speed perimeters 45, infill 60, travel 250mm, first layer 50%
filament 2.9 (measured), multiplier .95
Those are the most important, rest is default.
Are you sure about the .35mm? Maybe you can try playing with the size, .3 or .4?
And yes, colors do matter, you have to change temp according to different pla color.
Succes
