Fantastic, it’s a great project to do with kids. Pretty soon your daughter will be writing custom mods to the Marlin firmware *. I built mine last year with my 16 yo son and we have fun demoing it at maker faires. He still has very specific plans to be a famous rock star very soon though.
* One mod I had to do was to kill the annoying screeching piezo beeper on the Full Graphic LCD. The XXL LCD on my printer has a pleasant click.
