About this generator

A perfect first layer is smooth, with lines that just touch. Compare the pads to see where the bed is too high or too low.

How to use

  1. Enter your bed size.
  2. Use the same layer height as your slicer's first layer.
  3. Keep the model centered on the bed when slicing.

Printing tips

  • Lines with gaps: nozzle too high there. Rough or transparent: too low.
  • Clean the bed before testing.

Frequently asked questions

How do I read the result?

Lines with gaps between them mean the nozzle is too high in that spot. A rough or see-through surface means it is too low. Adjust the leveling or Z offset and print again.

Which bed size should I enter?

The printable area of your bed, so the pads land near the corners.
