First safe actionRun the first safe check and change one variable at a time.
Proof targetA small representative test no longer shows the original symptom.
Match the failed area to the visual before changing a setting.
Repair progress0 of 8 complete
Step 1 of 8
Finish support marks and sand the surface as needed.
Keep the problem and target visual open while you make this change.
Why this matters
Coating cannot bond to the surface.
Setting or checkLayer height / orientation
Reduce highly visible stair-stepping before printing.
Expected result
The original symptom no longer appears during a representative calibration or short test print.
Step 2 of 8
Wash or clean using a method compatible with the material and coating.
Keep the problem and target visual open while you make this change.
Why this matters
Solvents attack or fail to cure on the material.
Setting or checkWall count
Protect against sanding through thin shells.
Expected result
Measurements, temperatures, motion, feed, or exposure remain stable through the complete test.
Step 3 of 8
Allow the part to dry completely.
Keep the problem and target visual open while you make this change.
Why this matters
Runs and detail loss occur.
Setting or checkPart split
Separate colours or difficult masking areas when possible.
Expected result
No new warning, collision, leak, electrical smell, unusual heat, or material damage appears.
Step 4 of 8
Mask functional surfaces, threads, fits, and LED openings.
Keep the problem and target visual open while you make this change.
Why this matters
Layers remain soft and trap solvent.
Setting or checkLayer height / orientation
Reduce highly visible stair-stepping before printing.
Expected result
The successful change is recorded with printer, material, slicer, nozzle or resin, and date.
Step 5 of 8
Test primer and colour on a scrap print.
Keep the problem and target visual open while you make this change.
Why this matters
Paint highlights rather than hides them.
Setting or checkWall count
Protect against sanding through thin shells.
Expected result
The original symptom no longer appears during a representative calibration or short test print.
Step 6 of 8
Apply several light primer coats with full flash time.
Keep the problem and target visual open while you make this change.
Why this matters
Coating cannot bond to the surface.
Setting or checkPart split
Separate colours or difficult masking areas when possible.
Expected result
Measurements, temperatures, motion, feed, or exposure remain stable through the complete test.
Step 7 of 8
Inspect under side lighting and sand defects before colour.
Keep the problem and target visual open while you make this change.
Why this matters
Solvents attack or fail to cure on the material.
Setting or checkLayer height / orientation
Reduce highly visible stair-stepping before printing.
Expected result
No new warning, collision, leak, electrical smell, unusual heat, or material damage appears.
Step 8 of 8
Apply colour and clear coat in thin controlled layers with adequate ventilation.
Keep the problem and target visual open while you make this change.
Why this matters
Runs and detail loss occur.
Setting or checkWall count
Protect against sanding through thin shells.
Expected result
The successful change is recorded with printer, material, slicer, nozzle or resin, and date.
