E3D volcano question
To those that have modified their mk3’s to volcano, what benefits have you found?
The ability to print at the same or higher flow rate without the extruded motor clicking anymore?
Lower print temp so that you can reduce stringing and oozing?
Still using 0.4mm nozzle with it?
Re: E3D volcano question
My case:
Print about 3x more material (28-30mm/s^3)
I keep same temperatures but if you wish to print at 20mm/s^3 max you can lower a bit.
Was using 0.6mm before and 0.6mm now with volcano, for me it's the best nozzle
So the main benefit is print much more plastic, but with the 0.4mm you will not hit volcano max. extrusion if you not boost the profiles exutrsion width, and to hit the max you will have to print very fast, which can cause problems to the part.
Example: 0,45 width*0,2 Layer*200mm/s = 18mm/s^3
So print at 200mm/s which is very high you still not hit the max. capabilty of volcano, you will need at least 300mm/s which is crazy.
That can do for infill but don't use it anywhere else.
But you can boost a bit the profile like i said, to use extrusions of 0.8mm thick
So: 0.8mm*0.3mm*120mm/s = 28.8mm/s^3, that is a good value for infill
You only take a real advantage of volcano if you go bigger nozzles, like 0.6mm or larger.
If you don't plan to upgrade nozzle the volcano upgrade is not a plus for you, rather than that can be more problematic (Installation can go wrong, firmware must be changed)
Re: E3D volcano question
I've settled on the 0.4mm nozzle, and I'm happy with it. I've also more or less settled on PETG, and with PETG I'm getting ~3x the extrusion flow rate as I was before the volcano. For around $30-$40, I can't think of anything else that has such a high bang for the buck. IMHO, it should be standard equipment on the MK3.
Re: E3D volcano question
Volcano is great for large prints or fast prototyping. I have a 0.3 layer profile that prints 3-4x faster than standard 0.2 profile using a 0.4mm nozzle. Ex, XYZ cube in 15 min. Go faster with larger nozzles. Even standard layer heights can print much faster.
If you print smaller, detailed objects, V6 is better choice. Gives you access to smaller nozzles and you get less stringing with smaller retractions with the smaller volume of the V6 nozzles.
Ideally, it would be simple to swap and use both depending on print. I'm working on a solution for that.
Re: E3D volcano question
In the meantime you can buy smaller than 0.4mm volcano nozzles on aliexpress, though I haven't tried them. They're incredibly cheap.
I'm able to print 1.2mm wide with 0.4mm layer height with a 0.4mm volcano nozzle. I wouldn't have believed it possible if I hadn't proven it to myself. So, a 0.4mm vocano nozzle does cover quite a range.

Oh wow. I'm surprised by that too. What print speed you running that at too?

Holy s*** lol. So you're using the volcano at its flow rate limit max (3x v6's which was 8mm/s^3 for PETG) and with a 0.4mm nozzle. 😆 Mental.
Is there any negative to the performance when printing things at the scale/size as you would with the v6? I.e. does it perform just as well as the v6 with a 0.4mm nozzle in its performance range (i.e. less than 8mm/s^3).
Thanks.
