.4mm nozzle for XL?  

RE: .4mm nozzle for XL?

The xl nozzle .4mm fully assembled is out of stock at the moment.    You can buy just the nozzle in the shop though.   

RE: .4mm nozzle for XL?

I have an Xl and a MK4. The nozzles are the same between them. I've had no issues printing with the 0.6mm nozzle in the XL. I suppose a 0.4mm nozzle is better for small detail parts, but that's not what I normally print.

There are also the fancy ObXidian nozzles if you want to print abrasives.

RE: .4mm nozzle for XL?

E3D has them in stock, well, they have 5 less than they did yesterday.

RE: .4mm nozzle for XL?

I would like to refer to my post in the "Single Head" section:

I just tested both printers (MK3S+ and XL) with "identical" parameters (0.4 nozzle, 0.15 quality layer). I chose the 3DBenchy Model. There was absolutly no difference between the results. The MK3 took about 1h 43 min and the XL 1h 20 min.

The pictures I took are not that good to be posted here. I think I chose the wrong filament colour (black).

I have printed some other things and I am still very happy (lucky) about the quality. There is not difference. With the 0.6 nozzle I had the impression that it was better for bigger parts as it seemed to be a bit more "rough". Not that it looked bad. When you have bigger parts you look at them from a greater distance and they are perfect.

In the meantime I did some further prints and still can find no difference in quality. The question you have to answer for yourself is what you print, what you aim for. With the 0.6mm you can gain some more speed. I experienced about 20 to 25%.

For me, personaly, the 0.4 is more suitable than the 0.6

Nozzle 0.4mm

Heater Block

Thermistor

Heater

I ordered everything. Makes swapping the nozzle much easier. 😉 

RE: .4mm nozzle for XL?

Filastruder also has the .4mm nozzles in stock. I personally bought two.

RE: .4mm nozzle for XL?

For those wishing to share Nextruder nozzle-sets (heater-block, heater, thermistor, nozzle) between and XL and a MK4, note that there is a difference thermistors.  The XL thermistors have a slightly longer cable because of the different arrangement of the nozzle to LoveBoard.  Order the XL thermistor to allow them to be used interchangeably between the XL and MK4.

That's what I've been doing.

RE: .4mm nozzle for XL?

Great information all. My very largest reason for this change was because of all the stringing issues everyone was having. There were a few fixes for this but the what appeared to be the easiest fix was to use a smaller nozzle BUT just 2 days ago Prusa finally addressed this issue and is supposed to have a fix. According to some the 6 nozzle will do as good as the 4 in detail as long as you can stop the stringing and its not as prevalent on prints with no color change. I believe I will start more color changes if I can cut down the time but yet to see. Here is another good vid if you haven't seen this yet

RE: .4mm nozzle for XL?

Should be a sticky... I got Mk4s before I learned of this.

RE: .4mm nozzle for XL?

Just ordered 5 sets by E3D to convert to a full V6 0.4mm ObXidian XL5 setup.

Thanks to all the great advice here and online I got some multi-color prints to work on my XL5, but its still far from acceptable for me. I'm aiming for highest quality parts even if it comes at expense of some time, so for me its a logical (though costly) choice. Though I also hope the smaller nozzle helps limiting the oozing/stringing. 

I'm doing a bunch of test prints now with 0.6mm so I can compare it to the 0.4mm when they arrive.

RE: .4mm nozzle for XL?

Really looking forward for this.  Good luck.

RE: .4mm nozzle for XL?

To share my findings

I have a full .4 Nozzle XL5 now (using the adapters to run standard V6 nozzles, using E3D ObXidian .4 nozzles) .
- Running firmware 4.7.2 (without klipper)
- Changed Lift-Z from 0.2mm to 0.4mm (in line with what I run on my MK3's, and blobs where causing nozzle to break of parts)
- Added the filament change custom G-code that lets the head fly back fast to reduce stringing.

The change was so much better that I decided to swap all my nozzles, at first I intended to leave 1 or 2 0.6 nozzles, but for quality is just way more important.

On the left the older 0.6 nozzles with all kinds of settings to try and get better print quality.
On the full right one print done with 0.4mm nozzle 0.2mm layer height and it directly was just good quality prints.

Running 5 colors on next print just directly worked fine!

So I would say the XL should have shipped with 0.4mm nozzles and the adjusted move order by default, that would have giving a much better out of the box experience to start from.

What type of time change was there?

RE:

You can test that yourself also by looking at the estimate times from prusa-slicer. They seem very accurate.

To give my times on the Pikepool (without Input shaper, and with default old XL firmware) : 
my settings with 0.4mm nozzle, 0.2mm layer height = 4:07
Same project but switching to 0.6mm nozzle  = 4:24

I don't know why... but the time got longer with 0.6mm. I did see it also change the infill from 15%@0.4mm to 20%@0.6mm, so I did change that back to match the 15%. Ofcourse I'm still using 2 perimeters and so the perimeters will be thicker. But for quality prints I like more perimeters more because they tend to hide internal structure/infill better.

So... I did not know yet its also faster for (some?) smaller prints...
Please let me know if I'm missing something.

RE: .4mm nozzle for XL?

Well this whole swap out with no notice it was coming kinna sux.   Knowing I was (originally) going to need 0.6’s I’d been buying up obsidian 0.6’s as they (infrequently) became available, and I still needed to land one more.    So now I have 4/5 0.6 obxidian’s, and just got notice the 5 head XL kit has cleared customs, only to find out it’d shipped with 0.4’s vs 0.6’s.   Great.

I havent’ had time to sit through the much longer queues to chat with anybody at Prusa about this change, but in an ideal world I’d be able to swap out the 0.6’s for 0.4’s..

So I have a fair bit of $ tied up in 4/5 obxidian’s that are apparently not going to be useful unless I dont’ mind putting up with a mess of stringing, which I most certainly am now keen on.

I can say this much, Prusa’s communications have gone downhill a bit from when I first ordered my MK3 and MMU2.   

RE: .4mm nozzle for XL?

Knowing I was (originally) going to need 0.6’s I’d been buying up obsidian 0.6’s

If you do need .6's then you just got a free alternate set of .4's, instead of an actually useless duplicate set of inferior material .6's, and you can use the adapter on a cheapo v6 .6 nozzle for your fifth to hold you down in the meantime. Or just use a .4 as your fifth.

So I have a fair bit of $ tied up in 4/5 obxidian’s that are apparently not going to be useful

So you didn't need them? and you're blaming Prusa because you preemptively bought nozzles you didn't actually need??

RE: .4mm nozzle for XL?

Many of us figured that the .4s would work better, especially with oozing being a major issue.  With all the teething problems, I wonder what kind of feedback they got from their beta testers???  Or how bad were the beta units that they problems they fixed were way worse then the issues we’ve seen?  I’m overall happy with my XL.  I’ve been doing some smaller prints with 4 colors, and have had thousands of swaps with out issue, but it seems that some of the issues should have been caught earlier.

RE: .4mm nozzle for XL?

I was surprised by the 0.6 nozzles, with no option to request anything else. I am switching from 0.6 Prusa nozzles to all Diamond 0.4's after running some tests. Buy once, cry once.  Maybe I'll leave a 0.6 on station #5 or something.
