SuperVolcano on a MK3s

So while doing some COVID-19 PPE printing on my MK3, I got a wild hair while waiting for prints and bought an E3D SuperVolcano Eruption upgrade kit.  Has anyone attempted installing a SuperVolcano on a MK3?  I see some references to Volcano installs but not a supervolcano.  Is anyone aware if this mod has been done, and of the firmware / hardware modifications necessary? Thanks

I know that the Volcano requires firmware modification to account for the loss of Z build space due to the longer heater block. I'd expect the SuperVolcano would require similar with even more Z lost due to the extended heater block.

I opted to install 3D Solex Matchless nozzles on my Mk3 and found that the 0.6mm version can process PETG as fast as my Mk3 extruder can feed it, with a maximum rate of close to 70mm^3/s. This is surprisingly close to the maximums I'm getting with a Volcano-style and geared extruder clone on another printer with a 1.0mm nozzle at 80-90mm^3/s.

Unless you're also upgrading your extruder to feed filament faster, I expect you'll run into practical limits on how much of an improvement you'll see over the E3D V6. The same will apply to upgrading with the TriangleLab Dragon series. The filament you're feeding will also have an impact. That same E3D V6 hotend with 3D Solex nozzle that handles PETG at 70mm^3/s can only push PLA at 22.5mm^3/s. It's a balancing act with many parts.

My testing notes are here and COVID printing notes here.

  • Thanks for the information! You bring up a good point on the extruder feed rate being a limiting factor.  I just realized i mistakenly got the 12v instead of 24v version as well, so I am may need to return the kit anyway so I will check out your recommendation as well. I have run .8 nozzle as well and titanium heat break, it will be interesting to see if the matchless makes that much of a difference.
