Notes
Free Samcraft UV test kit (nozzle check + overall test) after 30 days idle without vacation mode: woke heads (heat to 30 °C), printed color-only 1 layer, white-only 3 passes (his sweet spot for dark substrates; prints over a black box), varnish-only 1 layer. Standard DPI cuts print time a lot. In xTool Studio hiding a layer does NOT stop it printing; uncheck Output per layer. Nozzles were perfect after the month idle.
