How do you get set up to draw with the Eggbot? This page has the essential details that you need to get started, along with a video that walks you through most of it. |

It's best to start with a document that's 800 pixels tall by 3200 pixels wide -- you can use the Eggbot Template from the set of example files as a good starting point. Eggbot draws paths -- continuous lines -- not bitmap images, and not solid filled regions. Certain object types are automatically treated as paths, for example circles and rectangles. Other types of objects that are made of lines -- like outlined text -- may need to be converted to paths (Path menu > Object to path) before plotting. A good first plot might be the "Hello world" example file. | It's best to start with a document that's 800 pixels tall by 3200 pixels wide -- you can use the Eggbot Template from the set of example files as a good starting point.

If your stepper motors (Motor 1 and Motor 2) are weak, make high-pitch whining noises, exhibit jittery behavior, or produce inconsistent step sizes, you probably need to adjust the current setting on the EBB. | If your stepper motors (Motor 1 and Motor 2) are weak, make high-pitch whining noises, exhibit jittery behavior, or produce inconsistent step sizes, you probably need to adjust the current setting on the EBB. | ||

Use a tiny screwdriver to gently turn it fully clockwise, which will be from about 0 to 2/3 of a turn. Then, enable the motors from the Manual tab of Eggbot Control if they are not already enabled. Turn the potentiometer counter-clockwise until the motors provide moderate resistance to turning by hand-- usually about 1/3 to 1/2 a turn. NOTE: Some boards have a potentiometer that adjusts in the opposite direction. If your EBB board is red AND the potentiometer is made of white plastic, start by turning it fully counter-clockwise and then turn clockwise until the motors provide moderate resistance. |
* If the motors are moving but not performing correctly while plotting, you may prefer to begin a simple plot (for example, the "Hello World" example) and adjust the current while it is plotting. Note that the motors may behave differently while your screwdriver is actually touching the adjustment potentiometer. | * If the motors are moving but not performing correctly while plotting, you may prefer to begin a simple plot (for example, the "Hello World" example) and adjust the current while it is plotting.
