[1] Technically, these stepper motors have only 200 distinct steps per revolution.  However, fractional "microsteps" in increments of one-half, one-quarter,  one-eighth, and one-sixteenth can be generated with repeatable accuracy.  By having the EiBotBoard produce one-sixteenth steps, the Eggbot software sees the stepper motors as having 16&nbsp;&times;&nbsp;200 steps.  (In the 2009 EggBot Beta "clear-chassis" kit, each motor had 400 steps per revolution, and EBB v 1.1 had step increments only down to one-eighth, giving the same final resolution.)<br/>

[2] Inkscape will show on the left side of the screen a y-axis ruler whose zero point starts at the bottom of the page.  This is odd and annoying as that is not how SVG works and is not consistent with the underlying SVG which Inkscape produces.  Questions about this behavior and requests for an option to control are common on the Inkscape forums.<br/>

[3] A template size of 3200&nbsp;&times;&nbsp;800 is a good first choice.  Depending upon the size, shape, and mounting position of your "egg", you may be able to use height larger than 800&nbsp;pixels or may have to use a smaller size.  See [[Framing and Pen Centering]] for a more detailed discussion of this topic.<br/>

[4] Between plots, the program doing the plotting exits and this knowledge is lost.  When a plot begins anew, the Eggbot doesn't know what happened the last time it plotted.  The only exception to this is when you pause a plot with the PRG button on the EiBotBoard.  In that case, the Eggbot saves some data in your drawing file.  The plot can be resumed from where it left off assuming that you don't turn the egg or move the pen. (Or if you do that you can then manually restore the egg and pen to the position at which the plot was paused.)<br/>
