Also when automating the rapid fire with the new script set to 200 stacksize, it builds one turret then the steel stop transferring with plenty left in chest at 3 steel. This can be reset by deleting and re placing fast inserter but only works for 1 more turret.

Also after building the rapid fire turret and placing I noticed every single bot that had a repair pack decided it was hurt and wanted to fix it, maybe a bug?

Not seeing by opening any .lua files in wordpad that script anywhere, which one is it under? Also - the rapid fire takes that amount as well, so either set it to 100 or set two slots in recipe to take steel => it would only be able to be made in tier 3 assembler.

How do I change stack size?

How do you get the assemblers to accept more than 100 steel? the higher tier turrets take 200 and 100 is max they accept for production?
