Thanks for the in put. That draw on the wall printer head carriage is a novel idea, but I’m more for kicking my own starter. My intent is not to use a full size kit Maslow kit, but to build a scaled version, appropriate for the application. That uses the same developed geometries, and layout. If I can get a functional setup I envision using some canned g codes, a few french curves, that would initiate when he pushes his adaptive button. Essentially allowing him to scribble, just the same as we all learned how to draw. Then I’ll move him up to some canned circles, squares, stick people, ect
