Spool Change Log (Machine Matrix)

1. Enter the operator ID (shared for the whole batch, required).
2. Each matrix cell = one machine (e.g. F1-1A) and shows its current open spool (lot + install time).
3. For each machine changing spools, fill in that cell: new spool lot + length (m); residual is optional (leave blank or 0 when fully used).
4. Only cells with BOTH lot and length filled are submitted; other cells are skipped. Gray cells are disabled machines and take no input.
5. If the machine already has an open spool, the system treats it as a spool change: closes the previous one (recognizing kits from the residual) and opens the new one.
6. If the machine has no open spool, it's treated as a first install — no kits recognized (nothing to compare usage against).
7. Each cell reports success or failure independently (success shows the kits recognized); a failed cell does not affect the others — fix and resubmit just that cell.
8. To adjust the conversion coefficient or enable/disable machines, unlock "Coefficient & Machine Maintenance" at the bottom of the page (admin only).
