This tool has been deprecated. Inverse kinematics and calibration corrections are now handled directly in the Rep5x firmware. Use the Calibrator to calibrate your printer and the Firmware Builder to generate your firmware.

G-code Corrector Deprecated

Apply inverse kinematics (IK) and/or calibration corrections to your 5-axis G-code. Import calibration data from the Calibrator tool to compensate for measured errors.

3 Processing options

Apply inverse kinematics (IK)

Converts tool-tip coordinates to machine coordinates. Use if your G-code doesn't have IK applied.

Apply calibration corrections

Compensates for measured errors from calibration. Requires calibration data.

Firmware IK mode

Use if your firmware handles IK. Only calibration corrections will be applied to tip coordinates.

IK parameters

LC (mm)

LB (mm)

Values are auto-loaded from calibration data if available.

How it works

Inverse kinematics (IK)

Converts tool-tip coordinates to machine coordinates based on C/B axis angles and LC/LB parameters.

Calibration corrections

Compensates for measured deviations from the theoretical model using Fourier-fitted correction curves.

Processing order

IK is applied first (if enabled), then calibration corrections. This matches how calibration was measured.
