Optimize your factory layouts by calculating the exact number of assemblers and belt capacity needed for any recipe.
Assemblers Required:
0
Belt Saturation:
6.667% of a 15 belt
Total Power Consumption:
0 MW
Ratios are determined by aligning the crafting speed of machines with the recipe duration and your desired output rate.
Formula: Machines = (Items/sec * Recipe Time) / (Crafting Speed * Yield)
Machines = (Items/sec * Recipe Time) / (Crafting Speed * Yield)
To produce 15 Electronic Circuits per second using Assembler 2s (0.75 speed) with a 0.5s recipe time.
Productivity modules increase yield per craft but slow down crafting speed; you must adjust both variables for accuracy.
It is a multiplier applied to the base recipe time. An Assembler 3 has a base speed of 1.25, making recipes finish faster than the tooltip suggests.
