This thing consists of some hand (spreadsheet) generated g-code to test acceleration settings of Jetty's firmware:

or
http://www.thingiverse.com/thing:17855
The g-code does a back-and-forth motion over a range of distances (+-45 for X&Y, +-25 for Z), which will excite the bot at different frequencies, if one of those happens to cause a step to be skipped, theses scripts should find it.
Here is a video of operation on MiseryBot:

In the video the acceleration parameters are set to:
X max speed = 200, accel = 2000
Y max speed = 200, accel = 8000 (lighter stage)
Z max speed = 25, accel = 1000
