Nozzle Too Close to the Bed

Identify an over-squished first layer, scraping nozzle, blocked extrusion, ridges, and elephant-foot symptoms.

Start hereRaise Z offset slightly until extrusion becomes continuous and neighboring lines merge without the nozzle scraping or creating sharp ridges.

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.

Problem, repair steps and target result for nozzle too close to the bed — Match the failed area to the visual before changing a setting.

Repair progress0 of 6 complete

Step 1 of 6

Stop the print if the nozzle is scraping the surface.

Visual reference while completing step 1 of nozzle too close to the bed — Keep the problem and target visual open while you make this change.

Why this matters

The nozzle gap is smaller than the extrusion needs.

Setting or checkZ offset

Raise in small steps; the exact direction/sign depends on printer firmware.

Expected result

No scraping or clicking is heard.

Step 2 of 6

Inspect the nozzle and plate for damage or debris.

Visual reference while completing step 2 of nozzle too close to the bed — Keep the problem and target visual open while you make this change.

Why this matters

Saved compensation may not match the current plate.

Setting or checkFirst-layer flow

Use the profile default until height is correct.

Expected result

Lines are opaque and consistent.

Step 3 of 6

Raise Z offset in very small increments while running a first-layer pattern.

Visual reference while completing step 3 of nozzle too close to the bed — Keep the problem and target visual open while you make this change.

Why this matters

Hardware changes can shift the real nozzle-to-bed distance.

Setting or checkFirst-layer line width

Avoid extreme width as a substitute for proper height.

Expected result

Adjacent lines touch without tall ridges.

Step 4 of 6

Confirm the correct plate and mesh profile are active.

Visual reference while completing step 4 of nozzle too close to the bed — Keep the problem and target visual open while you make this change.

Why this matters

Correct height can still look overfilled.

Setting or checkZ offset

Raise in small steps; the exact direction/sign depends on printer firmware.

Expected result

Bottom dimensions are not excessively swollen.

Step 5 of 6

Return first-layer flow to the validated profile before compensating with Z offset.

Visual reference while completing step 5 of nozzle too close to the bed — Keep the problem and target visual open while you make this change.

Why this matters

The nozzle gap is smaller than the extrusion needs.

Setting or checkFirst-layer flow

Use the profile default until height is correct.

Expected result

No scraping or clicking is heard.

Step 6 of 6

Check that the nozzle is installed correctly and the hotend is mechanically secure.

Visual reference while completing step 6 of nozzle too close to the bed — Keep the problem and target visual open while you make this change.

Why this matters

Saved compensation may not match the current plate.

Setting or checkFirst-layer line width

Avoid extreme width as a substitute for proper height.

Expected result

Lines are opaque and consistent.

Controlled test log

Change one variable, then record what happened

This keeps temperature, retraction, speed, mechanical, and material tests from blending together. The history stays private in this browser.

No controlled tests logged yet. Record the first change before adjusting a second variable.

Do not repeat the full print yet

Prove the repair with a small test

Test modelSingle-layer five-zone test

Setup

Use the final plate, material, mesh and first-layer profile.

Pass condition

Lines join evenly in the centre and corners, with no scraping, gaps or lifting.

If it still fails

One or more zones remain loose, transparent, ridged or detached.

Recheck visual diagnosis

Complete the repair steps, run the proof test, and record the result.

Only if the proof test still fails
