Can you pause the pen while printing in order to change color. Also is there a control that allows the software to stop to allow a color change and then start again with a new pen?
One way to do this: based upon color, separate your design into different layers. Then print the design layer by layer, changing pens between each layer you print.
Does the egg bot always return to the exact spot it began? Also. Can you pause the pen while printing? I have had occasion where I wanted to stop the printing for a few moments but there does not appear to be any way to stop the prinitng until it is completed.
You may find it helpful to delve into the details of the Eggbot Extensions. In particular, the Options and Resume tabs of the Eggbot control extension cover those topics.
