Marlin configuration

Hi folks,

Working on getting my Marlin firmware set up for my prusa i3. I found instructions for setting the correct values for DEFAULT_AXIS_STEPS_PER_UNIT, but I am wondering how I determine how to set the following: (possibly other settings as well)

* HOMING_FEEDRATE
* DEFAULT_MAX_FEEDRATE
* DEFAULT_MAX_ACCELERATION
* DEFAULT_ACCELERATION
* DEFAULT_RETRACT_ACCELERATION
* DEFAULT_XYJERK
* DEFAULT_ZJERK
* DEFAULT_EJERK

My current prints are a bit rough and I want to try tuning the firmware. I have already made sure all the belts are tight.

Thanks!!

Check the reprap calculator (http://calculator.josefprusa.cz/) for a few of these settings.

Yeah I saw [calculator.josefprusa.cz] already. Just wondering about the rest of the settings.

Let me take some pics of the rough looking prints tonight.

I have noticed sometimes that the print head is moving quite fast, to the point where it causes the whole machine to wobble, even on a sturdy surface. This is especially true when filling in long, small gaps. I was guessing that some sort of speed settings need to be tweaked, but unsure what specifically.
