Objectives

  • Iron Rod >= 15.0/min

  • All inputs connected
  • Machines <= 6
  • Alternate: Cast Screws >= 150/min
  • Retire Screws
  • Mission constraints

Briefing from ATA

Production has approved Cast Screws. Change the screw constructors to Cast Screws and feed them directly from iron ingots. Keep fifteen rods and at least one hundred and fifty screws per minute available, using no more than six machines. You have sixty iron ore per minute. Whole machines at one hundred percent clock are enough. Open Hints if you need a nudge.

Mission constraints

  • Iron Ore: 60/min available
  • Available recipes: Alternate: Cast Screws, Iron Ingot, Iron Rod, Screws.
  • Available buildings: Constructor, Smelter.
  • Par time: 3:00 · a guide, not a deadline
  • Clock limit: 100%. Every goal can be met with whole machines at 100%. No fractional counts or precise clock tuning needed.
  • Remove obsolete machines, or change their recipe. An idle old recipe still counts as an unfinished retrofit.
  • No Somersloops.
  • Output targets count surplus available after your factory's own consumption.

Need a nudge?

Hint 1

Select the Screws factory and use the Recipe selector to choose Alternate: Cast Screws. Its new input is iron ingots, so reconnect it directly to the smelters.

Hint 2

Use two smelters, one Iron Rod constructor, and three Cast Screws constructors, all at 100%. They need 52.5 ingots per minute in total, within your 60/min ore supply.
