I'm a little confused to the actual diameter of the extruder nozzle on my Aluminum Prusa I3, I assumed it was a 0.4 but looking at the nozzle it is stamped 2-0 ? how does this number relate to the 0.4 nozzle ? is this a code ?

Thanks

actually the whole code should be "2-0.4" if your nozzle is a 0.4mm one; And if it is a nozzle for the 3mm filament, it should be like "3-0.4".

Thanks Mark, took a second look but can't see the "4", must be buried in the heater block.
