dont keep pressing any buttons except for your lasers each collector limpet has an expirey time and that depends on the module size and grade as i dont know your modules its hard to say more on that but you can see it on coriolis E rated last 5 mins D 10 mins and A 12 minsplease explaijn this. How do I know I need a new collector. I just keep the button pressed!
theres a limit as well on how many can work at the same time again depending the module dont start another one till its needed when it says your cargo hold is full the refinery is still working till its full
