Changing the mold or resin on a recipe (and scaling amounts)
Swap a recipe's mold or resin — the swap saves as a new variant, and a resin with a different mix ratio gets a step review first.
You can point an existing recipe at a different mold or resin from the recipe page — Swap mold sits on the At-a-glance card, Swap resin on the specs card.
Heads up: A swap always saves as a new recipe — named after the original with
(mold swap)or(resin swap)on the end. The recipe you started from is never changed. If you were expecting the original to update in place, that's the one thing a swap doesn't do.
Changing the mold
Pick the new mold and confirm. Ellie copies the recipe onto it and resizes the amounts to fit — the total volume and every colorant amount scale by the ratio between the two molds' volumes.
Heads up: The resize needs a volume on both molds. If either mold has no volume set, the amounts are copied across unchanged — which will be wrong for the new mold. Set the volumes on both molds first.
Changing the resin
Most resin swaps just work: pick the new resin, confirm, and the copy is bound to it.
Some don't, and Ellie will stop you rather than save something unsafe. If the new resin mixes differently from the one the recipe is on — a different ratio, or measured by weight instead of volume — and the recipe's steps have Part A and Part B amounts written into them, Ellie refuses the swap and explains why: those written amounts were worked out for the old resin, and measuring the old ratio with the new resin leaves the batch short of one component, so it never fully hardens.
That message comes with an Open Ellie's step review button, and that's the way through.
The step review
Ellie reads your steps and rewrites them for the new resin — recalculating the measures, the working time, and the cure. You see your current steps beside her revision, and choose:
- Accept — this recipe's steps are replaced with the revision, and the recipe is bound to the new resin.
- Save as new — makes a copy on the new resin and leaves this recipe exactly as it is.
- Edit — tweak Ellie's wording or timings first, then Accept or Save as new.
- Discard — closes the review and changes nothing. The recipe stays on the resin it's on.
Heads up: Accept is owner-only, because it replaces the steps on a saved recipe. If you're an editor, the review tells you so up front and Save as new is yours to use.
Some steps aren't shown in the review. Those are the measure and safety steps Ellie writes herself — she doesn't reword them. They're kept when you save, and rebuilt from the new resin's own figures.
