Need a PEN TOOL - like tracer, but will leave a mark

[tjskydive]

I've made a cycloid drawing machine, but don't have a pen tool....

This a $900 spirograph machine.... I've made everything, but don't have a pen tool to make a mark on the white spinning "canvas" I created.

Any suggestions?

The tracer won't leave a mark on another object. Note the spinning white canvas in the youtube video. The arm moves AND the canvas moves

You can do it another way, but it will lag some. you can spawn tracers without any "ink" on them, so that they will make a line on the canvas and keep rotating. you'll need the spawn script, and then you can put it on the postStep of the object where you want your tracer spawned like:
postStep = (e)=>{Scene.addTracer( blah blah blah)}
I can make a script for ye but you'll need to wait
