These are a few of my favorite settings for using the Chomas Creations tools in 
the entire Cricut line. These settings will work in the Expression 2 and Cricut Mini.  If you are using the Chomas Creations adjustable holders for the original Cricut, Cricut Create, Imagine, or Expression, some of these pens and markers will not fit (they have to be under 3 1/2 inches).  If you have any you would like to add to the list that 
work for you leave a comment and I will add them here.  These are general 
settings that work for me.  You may want to practice with your machine and scrap 
paper to see if they work for you!
