I have mining machines that I've made on my server with Sync Pipes. However, I've seen an issue with the stone quarry that I haven't come up with a solution to yet that I like. Eventually the containers that I've set aside for stone fill up. However, I'm also smelting the metal ore into frags. I don't want the machine to die eventually when it can't move the stone out anymore and the quarry fills up. I'm looking for some added functionality, like the filter, that allows the machine to drop certain resources/items if it hasn't been able to transfer them after a certain amount of time. For this particular use case, that would mean that it would move metal ore and stone until it couldn't move stone anymore. Then it would start dropping stone to allow for the quarry to keep collecting metal ore. The subsequent machine hooked up to it for sorting out stone and smelting the ore would continue to work. This would include starting to sort stone again if the target boxes got some more space eventually. If you have another idea on how to fix this, I'm definitely interested in hearing it.
