Purge Tower Falling Over or Failing
Improve the tower’s first layer, width, cooling, speed, and placement, then reduce unnecessary tool changes or use a safer purge strategy.
Start hereImprove the tower’s first layer, width, cooling, speed, and placement, then reduce unnecessary tool changes or use a safer purge strategy.
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
Keep the problem and target visual open while you make this change.
Why this mattersThe small footprint cannot resist repeated nozzle contact.
Setting or checkTower width / volumeUse enough structure for the print height and number of changes.
Expected resultThe original symptom no longer appears during a representative calibration or short test print.
Keep the problem and target visual open while you make this change.
Why this mattersIt lacks stiffness at height.
Setting or checkBrimAdds stability without changing purge volume.
Expected resultMeasurements, temperatures, motion, feed, or exposure remain stable through the complete test.
Step 3 of 8
Increase tower width, brim, wall count, or density moderately.
Keep the problem and target visual open while you make this change.
Why this mattersLayers deform before the next purge.
Setting or checkPurge speedToo fast can create weak or displaced lines.
Expected resultNo new warning, collision, leak, electrical smell, unusual heat, or material damage appears.
Keep the problem and target visual open while you make this change.
Why this mattersDeposits build up and cause collisions.
Setting or checkTower width / volumeUse enough structure for the print height and number of changes.
Expected resultThe successful change is recorded with printer, material, slicer, nozzle or resin, and date.
Keep the problem and target visual open while you make this change.
Why this mattersThe tower sits in a cooler or poorly levelled bed area.
Setting or checkBrimAdds stability without changing purge volume.

Controlled test logChange 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.
Open proof report →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 modelSmall representative test print
SetupUse the same printer, material, slicer and key settings as the failed model.
Pass conditionThe original symptom is absent and the target feature is repeatable.
If it still failsThe symptom remains in the same location or stage.
Complete the repair steps, run the proof test, and record the result.
Only if the proof test still failsNext strongest repair paths
Do not stack these changes. Open one related guide based on the evidence that remains.
