Hi everyone,
Been playing for awhile but cant get past red/green science very well.

Had a couple of questions:

1) is there not a quick easy to replace inserters with fast inserters? Rather than removing the existing inserter and replacing it.

2) Is there a good tutorial on robots and the red ...

So I can get to where I complete all the research needed for the trains...
then though you need x of amount of materials...
something like:
3000 copper plates
3000 iron plates
1500 steel plates....

So on and so forth...

Unfortunately this is when I run out of iron ore near the area....
Is this ...
