How do I troubleshoot 3D print stringing and oozing?

Stringing is usually caused by insufficient retraction distance, excessive nozzle temperature, or wet filament (especially PETG and TPU). Doctor 3D UK analyzes stringing density from uploaded photos and calculates optimal retraction speed (30-50mm/s), retraction distance, and nozzle temperature lowering.

Why is my 3D print shifting layers along the X or Y axis?

Layer shifting happens when the toolhead skips steps due to loose motor belts, mechanical collisions with curled corners, over-tightened axis pulleys, or stepper driver overheating. Upload a photo to Doctor 3D UK for mechanical axis alignment recommendations.

How do I fix first layer bed adhesion issues and print warping?

First layer failure and warping occur when the nozzle Z-offset is too high, bed temperature is inadequate, or the print bed needs cleaning with isopropyl alcohol. Doctor 3D UK guides you through Z-offset micro-stepping, bed temperature adjustments, and brim/raft slicer settings.

How do I fix under-extrusion, gaps, or nozzle clogs?

Under-extrusion and wall gaps stem from partial nozzle clogs, slipping extruder gears, low printing temperature, or incorrect flow rate (extrusion multiplier). Doctor 3D UK recommends cold-pull nozzle unclogging and volumetric speed tuning.
