So you think this is the same as the worldedit plugin? https://www.curseforge.com/minecraft/mc-mods/better-builders-wands
I know some servers have the generators like these on survival. https://www.instructables.com/id/How-to-Make-a-Cobblestone-Generator-in-Minecraft/
Forgot to add to the original post about if this works be defualt or need a seperate plugin for it on minhut servers https://minecraft.gamepedia.com/Tutorials/Automatic_smelting
Sorry if this seems odd I am trying to setup a private server for the first time for a group of friends to use the tools I mention makes the experience more manageble.
