Can you tell if has v2 or v1 extruder
I am unsure if Zortrax keeps those kinds of records, however most printers being shipped by re-sellers and Zortrax main are shipping with V2 nozzles as a standard part.
I can't answer you but I think you should not put your serial number on a public forum. Support service may help you. Send them an email
Post a pic of the hotend and we can tell you. Make the pic from the side so that we can see the stainless tube section.
