Package contains: 1 x Volcano aluminum block.
This block can be used with the nozzle Volcano and all E3D and compatible extruders except the Cyclops.
The same thermistor mounting configuration as the V6 can be used. Also there is a locking system for the heating cartridge to allow maximum heat transfer, using two screws to stop it. One must use the nozzle extra volcanoes since the classic nozzle short ones would result in the molten plastic leaking out. This creates a variety of problems, including the inability to print and reuse the block itself, as the plastic would be deposited in the inner fastening thread.
