Tony,
When I first decided that I wanted to try 3D printing it was important that I got something that would work straight out of the box to instill some confidence!
The Ender 3 Pro seemed to fit the bill and was very easy to put together and get a first print done, a Benchy like everyone does!
I design my stuff in Fusion 360 and it was recommended to use Cura as the slicer software, this proved to be pretty easy to use with just basic settings.
The only real problems were getting the bed REALLY level and I did also swap out the supplied bed for a more expensive one with better adhesion.
Auto leveling is, I hope, going to be a game changer for me. I only print PLA and only buy Creality or SUUNLU filament having had poor results with cheaper stuff.
I have not tried ABS or other filaments as The War Office deems our house a no smell or smoke zone!
Resin seems to be out of the question, it looks really messy!
I had never ever anticipated that this could be a useful source of income in my wildest dreams. Hence buying another printer to up my game.
