Calibration

Guided setup for accurate inspections

The Optysys setup wizard walks operators through a step-by-step calibration process. From GRBL axis configuration to zoom-level regression, every parameter is tuned for your specific hardware setup.

Setup Wizard

Step-by-step hardware configuration

The multi-step setup wizard guides new installations through every calibration parameter. Jog controls are available within the wizard for real-time adjustments.
  • GRBL Calibration
    Calibrate steps-per-mm for X, Y, and Z axes. Configure maximum travel limits and soft limits for safe operation.
  • Homing Setup
    Configure homing routines with limit switch polling. Establish a reliable reference position for repeatable inspections.
  • Work Area Definition
    Set the XY work area dimensions to match your physical inspection area. Coordinates are automatically bounded.
  • Zoom Calibration
    Polynomial and logarithmic regression analysis maps zoom levels to field-of-view dimensions for precise measurements.
Mathematical Calibration

Regression analysis for precision

Optysys uses MathNet.Numerics to fit calibration curves that map zoom levels to real-world dimensions. These curves are calculated automatically from calibration data arrays and stored in the configuration.
  • Polynomial Regression
    Configurable-degree polynomial fitting for width and height vs. zoom level calibration curves.
  • Logarithmic Regression
    Log-based fitting for zoom calibration curves with inverse calculation support.
  • Newton's Method
    Iterative root-finding for inverse calculations -- determine zoom level from desired field-of-view.

Calibrate once, inspect with confidence

After initial calibration, all parameters are persisted in the application configuration. Recalibration is only needed if the hardware setup changes. The regression data is automatically loaded on startup and used throughout the inspection workflow.
