I personally farm off the main server nowadays, and then world hop back to the main server with a 100% full inventory and completely over encumbered. Cuts out the travel time and keeps me from completely destroying the environment of the main server. Stone is super easy to farm from the pillars in the plains, wood I just elder buff with stamina food and chop everything down in sight for 5 minutes. Iron is also easy, just find a seed on the map viewer that has a high crypt density swamp that is relatively close to the spawn point. It's a good way to do things if you don't want to just spawn in materials with the console.
