Tammy, ecal2 auto sets pressure and speed etc based on the media you choose. I find it pretty accurate. Try some cuts on card stock (light, med, heavy) and contac paper to see how your particular machine conforms.
I have not seen any in depth videos on how to for either scal4 or eclips2. Scrappydew did a hangout wth a guest who walked through some of the features. If you go to scrappydew.com you can find the link to the hangout. I am pretty sure the link is on the forum here too.
See this post for starters.

A search on this forum has tips and tricks too.
Have fun exploring.
