Yep, I've been experimenting with metallic gel pens on black paper, the result is pretty nice:

The Uni-Ball Signo metallic gel pens have performed pretty well, but can drip on the corner when the piece is done and the arm returns to origin, so you'll want to pay attention to it:

You need to run your SVGs through some path optimization! Your Axidraw is doing a lot of unnecessary traveling between lines. Check here: https://github.com/beardicus/awesome-plotters#vector-utiliti...

I know, I just didn't bother to do it for that piece since I actually wanted to film the jumping around of the arm as a demo for friends. I do it for other pieces I actually want to optimize using vpype.

Sakura Gelly Roll White pen is great as well.

Love it, going to try them out. What paper do you use?

Looks like its unavailable for me right now, but there are others you can try.

For white paper, this has worked very well for me: https://a.co/d/9qoDwML

Thanks! Was surprisingly hard to find something that looked good on Amazon. I'm thinking it has to be matte for the full effect. Probably worth checking out an art supply store.

Probably. Its definitely worth investing in good paper and pens for this hobby. There will be some experimentation tax built in too, I've bought pens that ended up being garbage but there's no way to know that until you try.
