Sorry if my english is bad I'm a french guy.
My idea is to add to every machines a button wich toggle a loop process. In other word, when you push this button the machine will run until there's no more resources to run( it will wait like a few seconds and then shutdown if he hasn't enough resources or places to put the result. It will be usefull for the soil centrifuge, the printers, the chemistry lab, ... Because you always need to push the button everytime it's over but if you have like 5 of them it become difficult to manage to do it.
Thanks for reading.
