heh, Katherine of sky had a nice setup I saw. have a worker bot making the tools. for them, they go to plank, grab plank, Q to stow it, then go to sticks, grab stick then go put the stick in the tool bench, then , or. (comma or period) to cycle item from inventory to hand. stuff that into the tool bench. then fetch tool, then stuff tool into item chest. do this till storage of tool is full, then repeat forever.
as to the worker. have tool storage within their work zone area. now for commands for say lumber. [{until hands empty] find tree, move to tree, cut tree] follow this with goto tool storage, grab tool, then bind this in a until storage full on logs. and follow that with a forever grouping around that.
