Decision framework
Classify the requirement before changing the process
Use HF-200ECR when a rigid, repeatable contour needs a taught roller path that can be supported and reached without interference. The verified 140 mm pattern width is a size boundary, not proof that every shape inside that width is printable.
Prove the part is repeatable
Compare several parts at the intended locating surfaces. Variation in moulding, deformation or loading posture must be corrected before teaching a motion path.
Establish fixture datum and support
Contour learning records a relationship to the current fixture and product posture. A loose or changing datum makes the stored path invalid even when the same recipe is selected.
Teach only the accessible path
Check the full roller, fixture and part clearance before hot contact. Sharp transitions, deep recesses and weak unsupported walls may require a different contact route or tooling.
Use local compensation second
Relearn after restoring the datum. Apply angle-specific correction only when a local defect returns at the same contour position on repeated trials.
Field diagnosis
A check sequence from symptom to proof
| Observed symptom | Priority judgement | Check first | How to confirm |
|---|---|---|---|
| The whole path is shifted | Fixture datum, part posture or wrong recipe identity | Verify the physical fixture, locating surfaces and selected product group before editing the taught path. | Restore the datum and relearn with settings otherwise unchanged; the global offset should disappear. |
| One local area remains light | Residual local geometry, support or contact-path mismatch | Confirm the mark repeats at the same contour position after a complete relearn. | Change one local correction only and verify the predicted area on consecutive parts. |
| Contact becomes stationary during a stop | Abnormal recovery left the roller against a heated part or tool | Use the machine-specific safe recovery procedure to remove hot contact before investigating the cycle. | Restart only after clearance, motion state and product condition have been checked. |
| Results vary after recipe recall | The recipe returned but the physical fixture, part or tooling state did not | Compare the current physical setup with the setup used for the approved taught path. | Complete dry validation, warm trials and consecutive-part checks before release. |
Release criteria
What a stable result looks like
- The fixture and part reproduce the approved datum without looseness or posture change.
- The full taught path clears the fixture and part before thermal trials.
- Contact coverage and edge definition remain acceptable through the complete contour.
- Consecutive parts repeat the approved result after normal loading and recipe selection.
