xTool F1 Ultra slate settings

8 tried and tested slate and stone settings for the xTool F1 Ultra, covering slate, brick and colour fill (powder coat). Every recipe here has been run on a real F1 Ultra in the L3D workshop before being added, with prep tips and notes where they matter.

Every machine is slightly different. Treat these as proven starting points and always run a small test first.

F1 Ultra + slate: common questions

Do I need to prep slate before engraving?

Coasters straight out of the pack usually engrave well, but a quick wipe to remove dust helps. For photo work, a light sand or a clear coat gives a more even surface, and painted slate needs thin coats of white then black for the highest contrast.

Why does slate engrave lighter or darker than expected?

Slate varies a lot between batches and suppliers, and focus height makes a big difference. Start with the settings here, run a small test in a corner, and nudge power up or down in 5 percent steps.

Why do my results look different to yours?

Materials vary between batches and suppliers, machines drift, and focus matters. Treat every number here as a proven starting point, run a small test first, then adjust in small steps.
