New to 3D printing. I am looking for a 3D printer, during my search I was planning to going the prusa route... but I need something more like IDEX? I want it to have 3-4 extruders to print multiple copies at the same time. Flashforge has 2 but its expensive and I could get 3 printers for that price!

How can multi extruder be set up? Can Prusa or prusa XL be upgraded for this? If not what is a good printer with decent size bed for this?

And is duet the board or is it firmware or both? I need help sorting this information out and be pointed in the right direction so I can build a multiple extruder machine.

Also what would be the highest possible extruder count?
