Bed Leveling Gap Helper

Inputs

Target Gap (mm) Typical: 0.20mm for a 0.20mm first layer. Use your preference. Bed Screw Pitch (mm per full turn) Common springs/knobs vary. Example 0.70mm/turn. If unsure, try 1.00. Rounding Helps translate to real knob turns.

Measured Gap (mm) at each point

Measure using a feeler gauge or “paper drag” method. Enter the estimated gap in mm.

How this works

If a point’s measured gap is larger than target, the bed is too low there → raise bed (or lower nozzle).
If a point’s measured gap is smaller than target, the bed is too high there → lower bed (or raise nozzle).
Turns = (measured − target) / pitch
Direction depends on your printer’s knobs. This tool outputs “Raise bed / Lower bed”.
