If you look through the book and can view all the recipes with no issue, that's great! But you will notice that most recipes are locked. This is the default. In general, to make or use an SF item, you need to research it. This is done with normal XP levels. Each research has a corresponding level requirement.
After you have built up your XP levels, Click the “Basic machines” tab and learn how to create an “Enhanced Crafting Table.” The Enhanced Crafting Table will help you make new parts and materials which will be required to make new machines. tool, weapons, and foods!
To create multi block structures like the Enhanced Crafting Table, use the recipe provided after learning the item! For instance, the Enhanced Crafting Table's recipe calls for a dispenser and a workbench to be placed on top of that. So that's how you build it! It actually is pretty simple.
Now learn some more machines and start branching off into new topics within Slimefun! Items, Tools, Resources, Magical Armor, Food, Etc! One thing I suggest is crafting a set of slime armor! Its under “Magical Armor” on the second page of the book or if you using inventory mode of the guide, The golden chest plate on the first row Items 5-8. Remember to start small and then get bigger, don’t overwhelm yourself!
