Reviving Old Industrial Robot to Make ART

Recently finished reviving an ancient SCARA robot, adding a modern control software, giving it a paintbrush and with the help of comrades python-ing it into painting with a paintbrush.

Its a bit heavy on the robot mechanical and electrical side, but there's a github repo of image processing to synthesize the brush paths and I thought you folks might be interested.

The robot documentation is here: http://transistor-man.com/bluebot_revival.html

A quick video demo: https://vimeo.com/213723506

This is also an entry into the robotart competition, there's a login to vote for art that interests you.

Our team didn't have access to a brand new robot, so we revived a scrapped one

So on your method of replenishing paint, does the G-code auto generate that subroutine every (X) mm of line painted? Also how exactly does that work with Linux-CNC, is it inserted like an insert/swap tool command?

Second question; Does the G-code look similar to a 3d printer? Like are you just 3d printing with colored paints? (if so, is that common among robot painters?)
