Demonstration at a shared layer power of 60%. Commanded power = layer power x object Power Scale / 100.
  1. Open power-scale-start.lzrproj. The three 20 mm squares share a Line layer at 60% power and 1200 mm/min.
  2. Select Middle square in Outliner. In Properties, set Power Scale % to 50, then press Enter or Return.
  3. Select Right square and set its scale to 25%. Left square stays at 100%. No object needs moving or resizing.
  4. Check Layers: shared Power is still 60%. Power Scale multiplies that value; it does not replace it.
  5. Open Preview, hide Show Travel and enable Shade by Power. Compare the planned power shades.
  6. Close Preview. Try restoring Middle square to 100%, then return it to 50%. Save a separate copy and compare with power-scale-finished.lzrproj.

Independent practice

Open power-scale-practice.lzrproj. Keep the shared layer at 40%. Leave Left square at 100%, set Middle square to 75%, and Right square to 25%.

  • Keep the layer at 1200 mm/min and preserve all three square sizes and positions.
  • Calculate each commanded percentage before inspecting the Preview shading.
  • Save your own copy and compare with power-scale-practice-answer.lzrproj.
  • Left square commanded power:
  • Middle square commanded power:
  • Right square commanded power:

Explained answer

Practice calculations
40 x 100 / 100 = 40%. 40 x 75 / 100 = 30%. 40 x 25 / 100 = 10%.
Scale and size
Power Scale changes the object multiplier. Geometry stays 20 x 20 mm for every square.
Preview interpretation
Shade by Power displays planned power. It does not predict engraving darkness. Material, speed and focus still matter. Power Scale is separate from machine S-value Max.
  • power-scale-start.lzrproj

    Demo: 60% layer; all scales initially 100%.

  • power-scale-finished.lzrproj

    Demo answer: scales 100%, 50%, 25%.

  • power-scale-practice.lzrproj

    Practice: 40% layer; all scales initially 100%.

  • power-scale-practice-answer.lzrproj

    Practice answer: scales 100%, 75%, 25%.

The demonstrated release accepts Power Scale from 0 to 100%. A scale of 100% restores the full shared layer percentage.
