External materials speed/flow ratio slider working?

Hi, using Z-suite 2.18., model in shell mode. There is no difference in wall thickness and print time, regardless of the slider settings for flow and print speed. Even with a big part the printing time is exactly the same - 10h 3 min- with print speed -50% and +50%.
Does this feature work at all in shell mode?

Many thanks for the many asnwers, helps a ton.


Sorry for late response.

As shell is a specific infill type only the bottom layers would be affected by those settings.

Also I would advise to update your Z-Suite Version to the latest 2.26 or the Beta 3.0 if you own a M200/300 Plus/Endureal printer and want to try it’s new features.

Best Regards
