I went to Menards over the weekend, and picked up some polyester rope, which has almost no stretching issues. I was previously using 550 paracord, as it was all I had on hand. Additionally, I now have 3 turns of rope on each pulley, so there is plenty of friction to move the curtains.
Another upgrade was the replacement of the 9V power supply with a 12V supply. The motor I use is 12V, so it was initially underpowered. Now, it is working better than ever.
I still need to implement the hall effect sensors to eliminate the timed opening and closing.

The curtains are up and running!
They are controllable via HTTP requests, and are integrated into our Smart Home hub (which should also be a project on here some day...).
Additionally, through emulating a Hue bridge, the curtains are controllable with voice commands and Alexa.
The code will be on GitHub soon, and I will post the models as well.
