We are the conductor of your print farm

When a job goes into the queue, SimplyPrint reads the file's bed type, material, nozzle size and colour from the slicer metadata, then compares those requirements against every printer's currently loaded filament, mounted plate, nozzle config and tags. The job only becomes runnable on printers that satisfy every active constraint - that's why 1-Click Print and AutoPrint can fire off a batch with no manual matching. Print bed size, max temperature, multi-material configuration and printer model compatibility are also factored in, so even a file with no tags at all won't be sent to a printer that physically can't run it.

The bottleneck on a print farm isn't usually print speed - it's the seconds (or minutes, or hours) between one print ending and the next one starting. Smart routing's job is to remove that gap. As printers report ready, AutoPrint pulls the next compatible job out of the pool - on a shared, in-memory claim ledger that prevents two printers from grabbing the same job in the same tick. No one has to decide "which P1S takes this PETG run?" - the conductor decides. Combined with multi-material mapping, filament-loaded tracking and printer maintenance mode, the matcher knows the real state of your fleet, not just the configured state.

Not every file comes from a slicer that writes clean metadata. For uploads from older slicers, downloaded prints or files renamed by hand, filename tag rules let you define regex or text-match rules against the filename - and any matching file gets the configured tags applied automatically on upload.

Example: a rule like ^(ABS|abs)_ tags any filename starting with "ABS_" or "abs_" with the ABS material tag. Combine multiple rules to catch your team's naming conventions and stop tagging files by hand entirely.

Available on Basic and above.

Open Settings → Queue once to pick which dimensions you want enforced strictly (e.g. material always required) and which ones to leave loose, define clusters and bed types specific to your fleet, toggle auto-tagging behaviour and author filename tag rules. After that, you don't come back unless something physical changes - a new printer model joins the fleet, you adopt a new plate type, or your team standardises a new naming convention.
