Access Machine Parameter Editor

Press MOD key, select 'Machine parameters', enter password, and navigate to the kinematic axis definition section. Locate parameters MP7500.0, MP7500.1, MP7500.2 which define the cylinder axis orientation vector [X,Y,Z] components.

Incorrect machine parameter modification can cause machine crashes. Document all original values before making changes.

Verify Rotary Axis Orientation Parameters

Check MP7110.0, MP7110.1, MP7110.2 (or corresponding parameters for your rotary axis designation) which define the rotary axis orientation vector. For a standard C-axis parallel to Z, this should be [0,0,1]. The cylinder axis vector must match this orientation.

Use the Machine Parameter documentation (press HELP key while parameter is highlighted) to confirm which MP number corresponds to your specific rotary axis designation (A, B, or C).

Align Vector Definitions

Ensure both the cylinder axis vector (MP7500.x) and rotary axis vector (MP710x.x) have identical normalized direction components. For Z-parallel configuration, both should be [0,0,±1]. Adjust the cylinder axis parameters to match rotary axis orientation.

Vector components must be unit vectors (magnitude = 1). For example, [0,0,1] is correct, but [0,0,10] will cause errors.

Save and Reboot Control

After modifying machine parameters, save changes and perform a complete control restart (not just emergency stop reset). The TNC must reinitialize the kinematic model with the new parameter values.

Perform a dry run test of all axis movements after parameter changes to verify proper kinematics before running production parts.

Review KinematicsOpt Protocol

Navigate to TNC:\system\kinemat\ directory using File Manager (PGM MGT key). Open the most recent .txt protocol file to review measurement results, standard deviations, and error messages indicating which measurements failed parallelism checks.

Look for 'Deviation' values in the protocol. Parallelism errors typically show angular deviations in the rotary axis alignment section exceeding 0.01 degrees.

Verify Calibration Sphere Setup

Ensure calibration sphere is mounted in a location accessible to all rotary axis positions required for measurement. Sphere center must lie on or very close to the rotary axis centerline. Check sphere diameter entry in KinematicsOpt cycle matches actual calibration sphere.

Calibration sphere must be precision grade (±0.0005mm sphericity) and securely mounted. Loose or deformed spheres will cause incorrect calibration results.

Delete Existing Calibration Data

In MOD > Kinematic Configuration, select the active kinematic and choose 'Delete calibration data'. This removes the faulty KinematicsOpt results while preserving the base kinematic definition from machine parameters.

Make a backup copy of the .kin file before deletion: copy from TNC:\system\kinemat\ to TNC:\backup\ using File Manager.

Re-run KinematicsOpt Cycle

Execute KinematicsOpt calibration cycle again using Cycle 451 (or appropriate cycle for your control version). Ensure probe is properly calibrated first using Cycle 461. Use slower measurement feed rates (F200-300) and multiple touch points per position for better accuracy.

Ensure machine is warmed up (run for 30+ minutes) before calibration to minimize thermal drift errors during measurement cycle.

Analyze New Protocol Results

After successful completion, review the new protocol file in TNC:\system\kinemat\. Verify that parallelism deviation values are within acceptable range (<0.005 degrees) and no error flags appear in the rotary axis alignment section.

Compare 'before' and 'after' compensation values in the protocol. Large changes (>0.1mm) may indicate mechanical problems requiring physical adjustment rather than software compensation.
