Printer extruder hardware

Post by bigsub »

Good morning to all (I'm in Italy), I've a doubt on informations about extruder hardware.
Is the NozDia1 variable intended for the nozzle's hole diameter?

Nozzle diameter is indeed the diameter of the outlet. This will be 0.4mm for a standard nozzle on many printers.

The Nozzle length is the length of the bore (or throat) and is usually 1.5 to 2 times the diameter (so 0.6mm for an E3D 0.4mm diameter nozzle)

The drive length is the distance from the nozzle tip to the centre of the extruder drive pulley and this value does not need to be exact.
