Hi Roxy, I have checked out the issues 3165, and thanks (and sorry) for the "new issue" discussion.
I guess I should have provided the version info when I raise a question. Sorry for my miss. I am using Marlin 1.0.2-1 (seems too old...^^)
I will take your suggestion to use the Marlin 1.1.0-RC3.

Thank you again!
