I thought this would be a nice addition. You know how you can change the colors of the materials you use in Cura and how you can assign each extruder a different color. Well I thought it would be a good idea to have a message at the beginning of the print that tells you where to put the sharpies then it says press button to continue. Once you press the button the printer heats up and starts the print.

The problem is: i don´t know which color the user wants to use and there is now way to input this in cura
