Great! So far so good.
I said it to early... I've some troubles, when there are many request propagated some controllers do not export items from chest. https://imgur.com/a/HjJIuH8
I've prepare also world save file, if you would like to look on it. https://www.dropbox.com/s/ntpu3lnoa2dtbpw/SEK2%20-%202210%202.zip?dl=1
Good example is coper wire ( top line, 2nd from left). Even there are plenty request for it further on right, it is released from chest occasionally only. I'm using crafting and recipe combinator to determine how many items are needed - it is changing often request amount. Is that the issue here? Or my approach is just too wild? ;)
What kind of control do you think of ? . Just enable/disable or changing the items in the flow ?
When using mentioned recipe combinator, it would be great to set sushi based on total amount of all items needed (in proper ratio, obviously). But if it is too complicated, on/off will be also fine.
