Holding it at 45 works well for e.g. a sharpie, but it didn't work quite as well for a ball point pen, which we ended up using.
We tried a bunch of different pens and eventually ended up on G2 for reliability and "rollability," if thats a thing. Way fewer dead spots than some of the other pens. Also, we could see remaining ink and swap out early.

It's bigger!
Seriously though, this was an off the shelf pen plotter (Axidraw) until I blew up one of the axes. So it's the same controller, same motors, same pen carriage, and one of the same arms. We simply took one axes and made it super long.
