Got my 3d printer a year ago. Started using Autocad, but Autodesk discontinued it, rolling all the functionality into Fusion 360 (plus some from other Autodesk products). F360 has way more functionality than I will ever use, especially the CAM and stress simulation functions.
I bought a Flashforge Creator Pro. It has dual extrusion, which I thought at first I would use,, but nozzle alignment is very fiddly. I bought a removable glass print surface as I didn't like the idea of scrapping prints off the heated and aligned integral print bed. I can't fault the machine otherwise. I upgraded the extruders to 'all metal hot ends'. I have also printed some add-ons for the printer from Thingiverse. Mostly from 'Dr Lex', who also has a useful informative website about his use of the printer.
The manual isn't very good and is a bit out of date wrt the current version of the printer.
The Flashforge slicer program, Flashprint, is pretty good I think. Easy to use and seems to give pretty fair results.
I have printed using PLA, ABS, PETG and ASA filaments and am experimenting with nylon and flexible filament, though thats very early.
Have you already bought a printer? If you would like to chat about any aspect, I am happy to share my limited knowledge.
