Color doesn't match: fixing a filament color mismatch in the queue

A free printer won't pick up your queue item, and the inspector (or the printer) says the reason is a color mismatch. This is a quick fix.

What this means

SimplyPrint uses tags to route the right files to the right printers - so a job only runs on a printer that can actually print it correctly, and you don't waste time and filament printing something on the wrong setup. A file or queue item can be tagged with details like its material, color, nozzle size and bed type, and SimplyPrint also checks things like whether the model fits and whether the printer can run the file. When a printer doesn't meet one of the item's requirements, the two won't match, and the item won't start on that printer.

In this case, the item's color is different from the color loaded on the printer. SimplyPrint matches color on both the color name AND the hex code, so two reds with different hex values can count as different colors.

How to fix it

• Load the matching color, or assign a spool of the right color.
• Group the two colors as equivalent with a color cluster, or map one color to the other.
• Or loosen the "Material colors must match" setting if the exact shade doesn't matter.
