Fix first-layer squish, flow, seam blobs, clearance, support intrusion, and cooling, then verify with a small print-in-place calibration model.
Start hereFix first-layer squish, flow, seam blobs, clearance, support intrusion, and cooling, then verify with a small print-in-place calibration model.
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
Inspect the sliced preview to confirm the gap exists at every layer.
Keep the problem and target visual open while you make this change.
Why this matters
The printer cannot resolve the designed gap.
Setting or checkClearance
Calibrate per printer, nozzle, layer height, and material.
Expected result
The original symptom no longer appears during a representative calibration or short test print.
Step 2 of 8
Correct Z offset and elephant foot.
Keep the problem and target visual open while you make this change.
Why this matters
Bottom gaps disappear.
Setting or checkElephant-foot compensation
Protects bottom moving gaps.
Expected result
Measurements, temperatures, motion, feed, or exposure remain stable through the complete test.
Step 3 of 8
Calibrate flow and pressure advance.
Keep the problem and target visual open while you make this change.
Why this matters
Extra material bridges the joint.
Setting or checkSeam position
Keep blobs away from bearing surfaces.
Expected result
No new warning, collision, leak, electrical smell, unusual heat, or material damage appears.
Step 4 of 8
Print a clearance coupon using the same settings and material.
Keep the problem and target visual open while you make this change.
Why this matters
Material locks the moving surfaces.
Setting or checkHorizontal expansion
Use only after measured calibration.
Expected result
The successful change is recorded with printer, material, slicer, nozzle or resin, and date.
Step 5 of 8
Place seams away from moving interfaces.
Keep the problem and target visual open while you make this change.
Why this matters
Small gaps soften and deform.
Setting or checkClearance
Calibrate per printer, nozzle, layer height, and material.
Expected result
The original symptom no longer appears during a representative calibration or short test print.
Step 6 of 8
Reduce stringing and unnecessary support inside joints.
Keep the problem and target visual open while you make this change.
Why this matters
The printer cannot resolve the designed gap.
Setting or checkElephant-foot compensation
Protects bottom moving gaps.
Expected result
Measurements, temperatures, motion, feed, or exposure remain stable through the complete test.
Step 7 of 8
Improve cooling and slow small features if needed.
Keep the problem and target visual open while you make this change.
Why this matters
Bottom gaps disappear.
Setting or checkSeam position
Keep blobs away from bearing surfaces.
Expected result
No new warning, collision, leak, electrical smell, unusual heat, or material damage appears.
Step 8 of 8
Free the joint only with safe controlled motion; do not force fragile parts.
Keep the problem and target visual open while you make this change.
Why this matters
Extra material bridges the joint.
Setting or checkHorizontal expansion
Use only after measured calibration.
Expected result
The successful change is recorded with printer, material, slicer, nozzle or resin, and date.
