About this 3D model

This thing consists of some hand (spreadsheet) generated g-code to test acceleration settings of Jetty's firmware: http://www.thingiverse.com/thing:15380 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: http://www.youtube.com/watch?v=ClZF8-G5ub4 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
