I filled up a bag of bones and started this tonight. I filled to just a bit below the full line and added some garlic, ginger, thai chili, salt, and more chili. Set on Manual for 120 mins and we'll see what we get. Bones were a mixture of chicken, pork, beef and shrimp shells. Here's picture before the lid went on:

Happy Instapot-ing!
