New to Corel X6 -- laser engraving

Hi...  I'm relatively new to Corel X6 and am wondering how others here that use Corel for 'laser engraving' have learned how to use it.  I'm looking for detailed tutorials that are step-by-step.   I've googled and found a few that way...  just wondering how others have accomplished their proficiency.

Comments / suggestions / links appreciated... 

Many thanks!!

 

BTW:  I have a Universal VLS 6.60
