I updated the instructable to reflect the new controller, and also the wiki, though some of that just points at the instructable. In other news, the new controller has now replaced the old in the trunk of the repository. New updates will be committed to the trunk rather than polargraph_controller_zoom, so those of you who have checked out of the repo directly, then you can switch to this trunk, or just dump the whole folder and start again from the trunk.
I’ve done some TSP stuff, based on the Evil Mad Science TSP guide that was written up for preparing artwork for the eggbot. Don’t be put off, it was easy!
Oh, and for extra credit, I will reveal that this drawing was made with a polargraph running …. standalone! Exciting isn’t it. I just turned the computer off and walked away, and the machine just kept on scribbling. It was a seminal moment.
I exported the queue to a .txt file on a microSD card linked to an arduino mega, and did it that way. I’ve started a new branch for this in the embedded code repo.
