− | + | A number of plotting related options are set with the "Options" tab. Most of these options need only be set once and then forgotten. They do not vary as you change your drawing media. | |
==== Reverse motion of Motor 1 (pen) ==== | ==== Reverse motion of Motor 1 (pen) ==== | ||
− | + | This option defaults to True (checked). | |
− | + | The “historical” EggBot coordinate system is such that when you print a drawing, the top of the drawing is oriented towards the headstock, and the bottom edge is towards the tailstock. Over time, we have generally found it best to reverse that, by checking both “Reverse motion of Motor 1 (pen)” and “Reverse motion of Motor 2 (egg)”. This way which we recommend, it is more natural to put the “fat” end of an egg (or the base of a glass ornament) towards the larger egg coupler, where it tends to perform better. You can, however, uncheck both checkboxes to point the top of your drawing towards the headstock. | |
==== Reverse motion of Motor 2 (egg) ==== | ==== Reverse motion of Motor 2 (egg) ==== | ||
− | + | This option defaults to True (checked), for the reasons described above. | |
==== Egg (x) axis wraps around ==== | ==== Egg (x) axis wraps around ==== | ||
− | + | This option defaults to True (checked). When checked, the EggBot will "wrap" long lines by just continuing to rotate the egg in the appropriate direction. This is especially helpful for drawing patterns on your eggs which look similar to tessellations. It will also allow a shortcut to return straight home in less than a turn, even when rotated by many turns. | |
==== Return home when done ==== | ==== Return home when done ==== | ||
− | + | This option defaults to True (checked). After finishing a plot, the EggBot will position the pen back to the plot's starting position. | |
==== Enable engraver, if attached ==== | ==== Enable engraver, if attached ==== | ||
− | + | This option defaults to True (checked). If you have purchased or built an [http://shop.evilmadscientist.com/productsmenu/partsmenu/297 engraving attachment] for use with your Eggbot, then use this option to enable or disable the engraver while plotting. Note that when this option is selected, the engraver will be turned on and left running throughout the plot and only turned off when the plot is finished. The engraver is not turned off each time the pen arm is lifted. | |
==== Curve smoothing (lower for more) ==== | ==== Curve smoothing (lower for more) ==== | ||
− | + | Fundamentally, the EggBot only draws straight line segments. When presented with a circle, arc, or cubic spline to draw, the EggBot approximates the smooth curve with many short line segments that follow the path of the curve. This approximation can be made to appear smoother by drawing even more, shorter line segments. Or, it can be made rougher be drawing fewer, longer line segments. The degree of smoothness is controlled with this option. The smaller the value specified, the smoother the approximation will appear and the longer it will take to draw. The default value of 0.2 is generally an acceptable value. | |
