Hi Guys, So I'm looking for other nozzle sizes for our UM3 Ext. and I noticed there are nozzle packs for UM2 and not for UM3. Next to that I saw you can buy a whole print core with another nozzle size for the UM3. But that's not necessary right? So anyone advice about what to do? Does the Nozzle pack from the UM2 fits the UM3? Or does a new nozzle pack will come for the UM3? And if so, when will it come? A lot of questions, hope you guys can help me out. Thanks anyways for your time! Pascal
