Hi!

I keep getting conflicting answers - can I use an 3mm e3d v6 nozzle on a hexagon hotend? Will most m6 threaded nozzles work on this hotend?

Thanks in advance!

Yes, you can 100% use a 3mm (or 1.75mm too if you wanted to also convert the barrel and extruder) E3dV6 nozzle in a hexagon. The only one you cannot use is one of the ruby tipped ones in a Taz 6 or a Mini because it doesn’t conduct electricity for the auto leveling contact with the corners. Most of the M6 threaded ones will work assuming they are electrically conductive.

edit: The super long nozzles like the ones intended for the volcano would fit, but you should avoid them for physics reasons dealing with cooling rates.

?? can I use a larger nozzle - .6 or .8mm on m Taz-5 for larger projects that would take 30 hours to print with the 3.5mm OEM nozzle ???  
— I assume that Cura would slice it correctly…  
— a .8mm nozzle would allow five times the flow of a 3.5mm nozzle — (64 / 12.5) — but could the heater keep up with the faster demand ???

3.5mm nozzle? The .8 should work. Like you said, the speed might need tweaking… but the slicer should account for the necessary extrusion speed. Extruding a little hotter could help the extruder keep up.

The .8mm would only print faster if you set the layer height to .5 (60% of the nozzle opening). The print duration would probably the same if you printed at a layer height of .2 or .3. Reducing infill could help print duration, but the outer perimeter print speed would have the biggest effect on speed.
