This is a guide on adding a configuration to your slicing settings that will add an FFF cooldown during long silver layers.
This Config is useful for parts with many silver features on a layer. Typically, the FFF nozzle remains at temperature (~200C) when printing with the silver head. If it takes a very long time to print a silver layer, plastic can ooze from the FFF nozzle and fall into the part. This Config lowers the temperature of the FFF tool below the ooze point of PLA (170C) while printing silver. When the FFF tool is re-activated, the printer will pause to allow the hot-end to return to temperature.
We recommend testing this on short prints to see how it affects your individual prints.
See this article for more detailed information about adding configurations.
