Hi everyone,Newbie here...looking to invest into a first 3D printer and am considering the Flashforge Adventurer 3 - I want a printer that's enclosed such as this model. Someone mentioned that I will need to use their own slicer program and can't use external ones such as Cura - is this true? Also, there's version 1 and version 2 of this particular model I noticed - for version 2 is it a flexible and heated pad? I'm seeing mixed specifications, so it's confusing.I'm open to suggestion on a good beginner 3D printer that's enclosed - not too cheap though.Thank you
