Description
Another geometric tiling for the Eggbot. This one somewhat reminiscent of Op Art. This drawing is in a 3200 by 800 pixel template.
Generating this and similar images is fairly simple. For example, this image was generated by drawing an isosceles triangle. Then it was "twisted" using the contributed "twist" extension under Extensions > Eggbot Contributed. The result of twisting was then cloned & tiled using Inkscape's Edit > Clone > Create Tiled Clones... tool.

Instructions
The drawing is in two layers:
1 - test -- this is a framing layer which you can plot (with or without a pen) to ensure that you have the pen's starting position where you want it. Plot this using the "Layers" tab of the Eggbot Control extension and select "1" for the layer. A short tick mark at y=800 and another at y=0 will be drawn.
2 - drawing -- this is the actual drawing.
If you are having slippage issues and the drawing leaves a gap between the start and finish, you can horizontally stretch the drawing a few pixels using Inkscape's transformation tools. Select everything in layer "2 - drawing" and then use Object > Transform. Select the scale tab and set the units to pixels.

Great Design! Just tried it with my new eggbot for Easter... but there was always a gap between the surrounding 'boxes' - right in the middle...
Had a similar problem with the OP_Art - the middle boxes were somewhat 'out of shape' / distorted...
Tried everything with the eggbot settings (mainly pen arm), also the 'transform / stretch' setting you recommended...to no avail...
Any suggestions? Thanks in advance & happy Easter!
Without seeing pictures, it's not possible to tell what issue you are encountering. Likely, it's either slippage at the egg coupler or suboptimal alignment of the egg which is then causing slight precession. You may want to post at the Eggbot forums or the eggbot google group.
