I've just started using S3D on my UM2. Can't thank you enough for posting your start code. The start code for the UM2 that came with the default set up for the Ultimaker2 Extended left a lot to be desired . . . Purchased 2 Ultimaker2 Extended at the end of last year (after a 5 day, less than satisfying experience, with an Airwolf AXIOM) to augment my 17+ years of SolidWorks design work. Starting to get the hang of it. S3D has some excellent features, but needless to say the learning curve is a bit steeper than Cura! Thanks again . . .
