All attempts to get these three parts to print using sequential printing will FAIL....due to a change in sequential printing behaviour introduced by one of the upgrades....can't remember which one.
When sequential printing multiple parts, if yo place them too close together the sequential printing doesn't work. Move them a little further apart...and sequential printing works. Overlap them.....forget it!
Some would label this as a bug......S3D will probably say its a feature. I label it as an unwanted and undesirable change in functionality that was ill-thought!
