I have two different types of printers the ultimaker 2 extended plus and a Large size big builder. This morning I am having an issue with my prints starting for both printers. Previous G codes created in simplify are working. Could there be issues with the G code not being created correctly?

Well maybe slice the same file and do a text comparison to see what changed from prior files you created. Maybe you accidentally changed something with the profile.
