I would like to adjust my prusa i3's (hesine) Marlin. Most of the current settings are good and accurate so I would like to keep them and have them as a reference. I mainly just want to adjust the extruder. The manufacturer of my printer didn't include a copy of firmware settings with the kit minus what's on the control board. Is there a way to view the settings on the control board?

Many of the parameters are printed when Marlin first connects with the host. They can also be printed on demand by various G Code commands.

There are MANY parameters, however, that are not visible anywhere other than in the source code.

That's what I figured. Thanks
