I really hate to ask this because it's probably obvious. Oh well....
I have installed a REPRAPDISCOUNT Smart LCD Controller. On the third line against the left margin, there is a symbol that looks like "FR" and has 100% beside it by default. When you twist the knob, it changes. I searched the web and their wiki, but can't find any instructions about what is being displayed. I assumed FR must stand for feed rate, but I diddled it a bit and didn't notice any changed.
What is this?
