== Notes on engraving vector lines == | |||
When using the "cut" mode to scratch thin lines into a surface | |||
(say, outlines of fields in a board game, when the full board is cut through), | |||
the laser is moved at high speeds (say, 150mm/s) with low power, | |||
but slows down when lines are bent too tightly. | |||
This is where the minimum cut power shines: | |||
The cutter will reduce power as it speeds down, | |||
to avoid burning through the material. | |||
If you set the lower bound too low, | |||
lines will get lost where it slows down | |||
(because the effect on the material is not linear, | |||
and 1% may not do anything at all any more). | |||
If you set it too high, | |||
the prolonged exposure on a single spot can send the laser all through the material. | |||
For test cuts, take a coarse and a fine sample from your picture. | |||

which has multiple colors to try out different settings, | |||
and lines of varying curvature to see the effects. | |||

Notes on engraving vector lines
When using the "cut" mode to scratch thin lines into a surface (say, outlines of fields in a board game, when the full board is cut through), the laser is moved at high speeds (say, 150mm/s) with low power, but slows down when lines are bent too tightly. This is where the minimum cut power shines: The cutter will reduce power as it speeds down, to avoid burning through the material. If you set the lower bound too low, lines will get lost where it slows down (because the effect on the material is not linear, and 1% may not do anything at all any more). If you set it too high, the prolonged exposure on a single spot can send the laser all through the material.
For test cuts, take a coarse and a fine sample from your picture.
A practical test file is slowdowntest, which has multiple colors to try out different settings, and lines of varying curvature to see the effects.
