E3D Nozzle X  

RE: E3D Nozzle X

There are multiple threads already about nozzle x on the forum.  As the forums search is bad though its best to use googles search and limit it to just the forum, for example by using -  site: https://forum.prusa3d.com/ nozzle x
in the google search bar.

Personally I've had a nozzle x fitted for over 3 years and use it for everything.  I do however run my own tweaked filament profiles with the temps upped slightly.  If you read some of the other threads you will also find discussion of tungsten nozzles mentioned which can also handle abrasives but dont require any profile changes.

RE: E3D Nozzle X

Thanks... In fact, I had tried to do a search on the site, but could not find anything.
Every time you replace the nozzle I guess it is necessary to repeat the calibration of the first layer, is that correct?

RE: E3D Nozzle X

Essentially yes.  Any time you change a nozzle you will need to adjust your live z.  If you stick with proper E3D nozzle though (or any of the quality brands really) you should not need to do a full recalibration though.  Not if you do it properly.

For example the last 4-5 times I've changed my nozzle the live z adjustment was with 5 microns of where it was with the previous nozzle.  That's down to the quality machining of the nozzles always being to specifications and careful nozzle change procedure.

If you are not sure then back your live z adjust back to zero (taking note of what it was for reference), change the nozzle using the E3D instructions (which differ slightly to the prusa ones and I think are better) and then do a first layer adjust using the Jeff Jordan method.  You will rapidly get it back to the perfect first layer squish again and it shouldn't be far off between old and new live z values.

RE: E3D Nozzle X

I bought an E3D Nozzle X, it came in a small plastic bag. Is this a "normal" thing for a nozzle costing around 40 euros? Is it usually sold without any packaging? There is no way to know if it is original in this way (it could be the hardened steel version as well). I'm trying it and I'm not thrilled by it for now, but I have yet to try some PLA composite filaments (carbon and stone).

For miniature or high resolution prints, would it be better to switch from a 0.40mm nozzle to a 0.25mm one? With Nozzle X (as long as it is really a Nozzle X) shouldn't I have problems with clogging?

RE: E3D Nozzle X

Plastic bag is normal - would you like to pay €45,- to have it in a nice box or something similar. Take it out of the bag, srew it into the heating block and you are fine. If printing carbon you will run into troubles with a 0,25mm nozzle. 0,4 will work (sometimes it is possible to run into troubles, but most time it will work). How filaments with stone behave I have no idea.
