Hi all,
I made [vibe coded] a little tool to run my AxiDraw straight from touch - currently via an SVG (save svg and send to plotter from inside touch) but it’s built on interactive control so I may work on that.
If anyone’s interested here’s a link: GitHub - vsps/axiTouch: Touchdesigner to AxiDraw · GitHub
The supplied toc also has a setup for continuous encoders based on a post by the legendary @FaustoB 
…and it makes pretty sine waves.
Please let me know if that’s of interest to anyone, I’ll keep chipping away at it when I have time!
