Balance mirrored cavities by gate area
PourA356Porosity4/5 confidence
What we learned
What worked
Opening the gate to the starved cavity by 2mm while leaving the runner alone.
What failed
Assuming a symmetric runner splits evenly. The part is only symmetric about one axis and the flow found that out first.
War story
Changing gate area is a ten minute file job on a printed tool. Moving a runner is a reprint. Always reach for the cheap change first.
