Why isn't this circuit setup working?

Post by illakunsaa »



I trying to make a foundry that makes all the turbo belt components in a single machine (ie turbo belt, turbo under ground and turbo splitter+all the slower variants). I have a separate foundry that makes gears, plates and tungsten and electronics are made in a different part of the factory. There is a looping output belt where finished and extra products go to be reused.

For some reason the foundry doesnt want to start crafting. As soon as it has the required materials for a recipe it switces the recipe and starts the process all over. What I'm doing wrong? The foundry that creates intermediates works fine and it uses mostly the same logic.

When your inserters pick up ingredients to supply the foundries, the item isn't on the belt any more, so it isn't counted any more, so the recipe is detected as having not enough ingredients any more, so it is not set as recipe any more.

This is a frequent design error. There are usually 2 different solutions:
- either you additionally read inserter hand content and foundry content and add it to the belt content so it isn't relevant any more where the ingredient actually is. Difficult to handle if you chain multiple production machines as in your case
- or you latch the recipe while the recipe should be crafted, no matter if there are still enough ingredients on the belt or not
