Startup Messages

Everthing is OK and works. I just want to add the additional feature of overriding feed speed with a potentiometer.

User Interface Software

WebUI or Universal GCode Sender

What happened?

I cannot find any information in the Wiki to achieve implementing the analog potentiometer.
