Auto-print: let the queue start prints by itself

Tick Auto-print at the top of the Print Queue. From then on, every minute, PrintSol starts a ready task on each printer that is free. It is one switch for the whole organisation.

A printer is free when it is

• in control mode and not out of service,
• idle, with its bed marked clear (a finished print still on the bed blocks it),
• reachable through a bridge heard from in the last 90 seconds,
• not already busy with a start, pause or stop on its way.

A task is ready when

• its part has a file and it has a colour, or at least a filament type,
• that filament is loaded: the exact colour, a very similar shade of the same type, or for type-only tasks any spool of that type,
• there is a slice for that printer's model, plate and the part's process profile. If not, PrintSol asks the slicer for one and tries again on a later round.

Tasks start in priority order, then by due date. A task pinned to one printer waits for that printer.

Why a task waits

Open the task popup: the line starting "Auto-print:" tells you, for example "Waiting for an idle printer with a clear bed". If slicing failed, the card says so and PrintSol tries again after an hour.

When a start fails

A temporary problem (bridge not connected, upload hiccup) is retried up to three times a few minutes apart. Other failures leave the task queued with the reason on the card, and Auto-print tries it again after 15 minutes.

Plan limits

On the Free plan Auto-print starts one print at a time. When that limit holds a task back, the Activity log says so once a day. Prints you start by hand with Go are never limited, and paid plans are not capped.
